I CODICI NUCLEARI

Scala INES ((International Nuclear Event Scale), adottata internazionalmente dall'IAEA (International Atomic Energy Agency):
- livello 0 (zero): Deviazione (non significativo per la sicurezza)
- livello 1: Anomalia, con conseguenze praticamente nulle per la popolazione e l'ambiente.
- livello 2: Guasto, con conseguenze sulle persone valutabili in dosi assorbite di radiazioni piuttosto basse
- livello 3: Guasto grave, con conseguenze sulle persone valutabili in dosi assorbite di radiazioni piuttosto basse
- livello 4: Incidente senza conseguenze significative all'esterno dell'impianto. Incidente con impatto esterno minore, con esposizione radiologica della popolazione circostante dell'ordine dei limiti prescritti. Guasto significante del nocciolo di un reattore nucleare o barriere protettive, con esposizione fatale di un lavoratore dell'impianto (Windscale -oggi Sellafield-, 1973; Saint-Laurent, 1980)
- livello 5: Incidente con possibili conseguenze all'esterno dell'impianto. Rilascio all'esterno di materiale radioattivo, in quantità radiologicamente equivalente ai valori compresi tra 100 e 1000 Tera-Becquerel (TBq), richiedente una parziale attuazione di pianificate contromisure (Windscale -oggi Sellafield-, 1957; Three Mile Island, 1979)
- livello 6: Incidente grave.  Significante rilascio all'esterno di materiale radioattivo, in quantità radiologicamente equivalente a valori compresi fra 1 e 10 PBq di iodio-131, tale da richiedere la completa attuazione di pianificate contromisure facenti parte di un piano di emergenza esterno al fine di limitare gravi effetti sulla salute della popolazione (Mayak, 1957)
- livello 7: Incidente molto grave. Rilascio all'esterno di un impianto di grandi dimensioni di ingenti quantità di materiale radioattivo (maggiori di 10 Peta-Becquerel (PBq) equivalenti di iodio-131) in un'area molto vasta con conseguenti effetti acuti sulla salute della popolazione esposta e conseguenze gravi sull'ambiente (Chernobyl, 1986)

4 Febbraio 1971 - USA: incidente da irradiazione A techician at a seed irradiation facility walked within 0.6 meters of a 7,700-curie cobalt-60 source, unaware that the source was unshielded. When the technician left the irradiation room, it was realized that the source was unshielded. His whole body dose was estimated at 50-400 rad (a dosimeter worn at the belt indicated 260 rad) with exposure to his hand of 600-1200 rad.

12 Febbraio 1971 - (incidente unità navale nucleare) Atlantic: The USS Great Sitkin (AE-17) arrives under tow at Roosevelt Roads, Puerto Rico, having lost power off the Virgin Islands when four spring bearings wiped. Sabotage is suspected.

15 Febbraio 1971 - Kurtchatov, Russia: criticità di incidente con uranio An experimental configuration was being used to test the effectiveness of reflector materials in a power reactor core. The experimental core used uranium oxide (20% U-235) fuel rods immersed in water to induce critcality. The test on 15 February used beryllium as a reflector, which was erroneously expected to behave similarly to an iron reflector previously used. Before all experimenters had arrived, a supervisor began adding water to the core tank without control rods actuated. The supervisor and another scientist saw a blue glow reflected from the ceiling at the same time neutron detection alarms sounded; they both left the room. The first excursion boiled some of the water into steam, expelling additional water from the tank; however, the water pump was still on and continued filling the tank, causing additional excursions before electricity supply to the pump was cut off about 6 minutes later. The two individuals in the room received localized doses to their feet of about 1500 rem; one was assessed a whole-body dose of 330 rem.

19 Febbraio 1971 - (incidente unità navale nucleare) Atlantic: Water breaks into the French diesel submarine Flore when a valve of the snorkel device malfunctions as the submarine cruises submerged at a depth of 15 to 20 feet off Toulon.

6 Maggio 1971 - (incidente unità navale nucleare) Pacific: The USS Hanson (DD-832) collides with the Soviet fleet tug Diomid in the Korean Straits, causing minor damage but no injuries. The Hanson conjectures the accident was caused by a deliberate attempt by the tug (with an icebreaker bow) to ram the Hanson. A sliding collision, however, was the only result.

8 Maggio 1971 - (incidente unità navale nucleare) Pacific: A Nationalist Chinese fishing boat sinks off Kaohsiung, Taiwan, when it attempts to pass between the tug USS Molala (ATF-106) and its tow ARD-22, striking first the bridle and then the bowof the ARD.

26 Maggio 1971 - Kurtchatov, Russia: criticità di incidente con uranio in acqua Experiments were being conducted to determine the number of uranium fuel rods (90% U-235) required to produce a critical configuration. Rods were placed in various geometries within a Plexiglas tank which was filled with water, with additional rods added a few at a time. Insufficient calculations had been performed regarding such an apparatus. At the completion of one experiment, the water was being rapidly drained, causing the rods to slump into a supercritical configuration. The excursion ejected water and fuel rod fragments from the tank. One technician received about 6,000 rem and died 5 days later; a supervisor received 2,000 rem and died 15 days later. Two others in the room received doses of 700-800 rem and suffered acute radiation sickness; they survived with long term health effects.

7 Giugno 1971 - (incidente unità navale nucleare) Atlantic: The French escort ship Surcouf and the Soviet tanker Busharov collide in the Mediterranean 60 miles south of Cartagena, Spain, at night, cutting the Surcouf in half and killing nine.

Navy sources at the Pentagon acknowledge there have been a "afew" leakages at the base during such transfers in the past, although none were disclosed, but also none were of sufficient size to endanger anybody.  Reportedly the Navy disclosed this accident only when rumors of a nuclear incident started circulating in New London.

31 Dicembre 1971 - (incidente unità navale nucleare) Atlantic: On two occasions in 1971 defective U.S. nuclear-powered ballistic missile submarine distress buoys accidently shot to the surface signalling the submarines had been sunk by enemy action and each set off "a massive U.S. alert," raising the "threat of accidental war." A spokesman for the Pentagon admitted there had been two involuntary releases in 1971, one in the Mediterranean and one in the North Atlantic. But in each case, he said, the submarine informed its home base immediately and "There was no alert of any kind." One release was due to a mechanical problem and one to a human error. The Navy said technical corrections had been made since 1971 to prevent a recurrence of the accidental launchings.

22 Settembre 1975 - Ionio meridionale, Italia. La portaerei americana Kennedy si scontra con
l'incrociatore  americano Belknap a duecento miglia da Taranto, nello Ionio meridionale. Scoppia un incendio che sfiora letestate nucleari dei missili Terrier e parte uno dei più alti livelli di SOS nucleare, denominato 'broken arrow'. L'incidente è reso noto solo nel 1989. "Se le fiamme avessero raggiunto le testate le possibilità sarebbero state due: o le testate atomiche sarebbero esplose con effetti facilmente immaginabili, oppure la nave sarebbe affondata in zona frequentata dai pescherecci italiani, con conseguenze ambientali molto gravi" (William Arkin, esperto di
questioni militari).

Kennedy (CV-67) and the USS Belknap (CG-26) collide in rough seas at night during air exercises about 70 miles east of Sicily. The overhanging flight deck of the carrier cuts into the superstructure of the cruiser setting off fires on the Belknap which are not controlled for two-and-one-half hours on account of frequent flarebacks. The
commander of Carrier Striking Forces for the U.S. Sixth fleet, reporting to higher commands shortly after the collision, declares a possible nuclear weapons accident -- a Broken Arrow -- stating there was a "high probability that nuclear weapons [W45 Terrier missile warheads] on the USS Belknap were involved in fire and explosions," but there were "no direct communications with the Belknap at this time," and "no positive indications that explosions were directly related to nuclear weapons." He also notes that casualties recovered thus far show no exposure to radiation. Nonetheless, monitoring and medical teams were "alerted to the possibility of contamination." He adds that the nuclear weapons on board the Kennedy were not affected. An hour after the Broken Arrow message was sent the USS Claude V. Ricketts (DDG-5), alongside the Belknap fighting the fire, reported that Belknap personnel said "no radiation hazard exists aboard." Six people aboard the Belknap and one aboard the Kennedy are killed. The Belknap suffers serious damage, is put out of commission, and towed back to theU.S. to effect repairs lasting four years. It returns to the fleet in 1980. Smaller fires and other damage on the Kennedy are quickly contained and the carrier continues operations. 22 Novembre 1975 - Italia.

23 Maggio 1978 - (incidente unità navale nucleare) Pacific: While workers are draining a piping system aboard the USS Puffer (SSN-652), radioactive water spills on the drydock surface at the Puget Sound Naval Shipyard, Bremerton, Washington.  A Navy spokesmen says that "less than 5 gallons" of slightly radioactive water spilled as the workers were draining the liquid into two five-gallon plastic containers, a routine operation. The spill, says the Navy, was due to the inattention of the personnel doing the draining. The water being
drained reportedly was part of the submarine's secondary cooling system.The drydock drain was contaminated, but was closed before any spillage escaped into the sea. According to the Navy, no workers were contaminated. Shipyard employees disputed the Navy's account, saying that the spill was much bigger, about 100 gallons; that response to the spill was slow; and that several workers suffered skin contamination. These reports could not be verified. Subsequently a contaminated 15-by 20-foot section of drydock is jackhammered up, sealed in drums and shipped to a nuclear waste site in Hanford, Washington.

9 Aprile 1981 - (incidente unità navale nucleare) Pacific: The USS George Washington (SSBN-598) collides with the 2,350-ton Japanese freighter Nissho Maru in the East China Sea about 110 miles south-south west of Sasebo, Japan. As it is surfacing, it runs into the underside of the freighter, damages itsit hull and causes it to sink in approximately 15 minutes, killing two Japanese crewmen (13 others are rescued). The submarine suffers minor damage to a small section of its sail.  The accident sparks a political furor in Japan, straining U.S.-Japanese relations a month before a meeting between Prime Minister Zenko Suzuki and President Ronald Reagan. The United States is criticized because: it took over 24 hours to notify Japanese authorities; the submarine and a U.S. P-3 Orion aircraft overhead did not make a rescue attempt; and the submarine was operating so close to Japan, less than 20 miles outside the 12-mile limit. The U.S. Navy initially says the submarine surfaced but could not see any ship in distress due to fog and rain. On 11 April President Reagan and other U.S. officials express regret over the accident, make offers of compensation and reassure the Japanese there is no cause for worry about radioactive contamination, but refuse to say what the submarine was doing so close to Japan or whether it was armed with nuclear missiles. Over the next several months as the controversy continues, the U.S.  Navy: accepts responsibility to preclude lengthy litigation; is criticized for its preliminary report which says the submarine and Orion claimed not to have realized the freighter was sinking; and relieves and reprimands the commanding officer and officer of the deck of the submarine. On 31 August the Navy releases a final report which concludes the accident resulted from a highly coincidental set of circumstances, compounded by errors on the part of some members of the submarine crew.

The crack does not affect the operation of the reactor and the vessel returns to Devonport under its own power. The Royal Navy denies claims that contaminated water was discharged into Plymouth Sound, saying "A very small quantity of water leaked outand this was drained off into a lead tank in a barge for treatment." The reactor is cooled down before the leak is plugged.

26 Maggio 1981 - (incidente unità navale nucleare) Atlantic: A Marine EA-6B Prowler aircraft crashes while landing on the USS Nimitz (CVN-68) operating 70 miles off Jacksonville, Florida, killing 14 and injuring 48.

It was towed for a total of 36 hours but was actually only moved during darkness." The submarine was towed to Kaliningrad and "the sailors that had been sealed in the compartment were then flown to Riga and hospitalized." The CIA source reports all the sailors exhibited signs of terminal radiation sickness.

27 Ottobre 1981 - (incidente unità navale nucleare) Atlantic: A Soviet Whiskey class diesel-powered attack submarine runs aground 10 kilometers from the Swedish naval base of Karlskrona, 300 miles south of Stockholm. The Swedish government alleges the submarine was engaged in illegal reconnaissance or mine-laying work and there was good reason to believe the vessel is carrying nuclear weapons. The Swedes demand an apology and an explanation. When the submarine captain is questioned he contends bad weather and a faulty compass led to the inadvertent intrusion into Swedish waters. But the Swedish authorities maintain that good navigation was necessary for the vessel to come this far into their waters. On 29 October a Soviet tug is turned back by Swedish warships and another unidentified submarine is spotted within Swedish waters and is pursued by Swedish antisubmarine warfare helicopters until it disappears. On 2 November the submarine is refloated by Swedish tugs to prevent heavy seas from battering the ship. On 5 November the Swedish government announces that the submarine probably has nuclear weapons aboard. Foreign Minister Ullsten says "it must be very embarrassing" to have this information released when the Soviets "have created the impression that they are more in favor than the United States" of arms control. On 6 November the submarine is returned to the Soviets. The same day the Swedish government expresses the view that previous Soviet proposals in regard to the Baltic as a "sea of peace" were no longer credible.  Officials said the incident would affect Swedish attitudes toward Nordic nuclear-free-zone proposals from the Soviet Union. It is later reported on 6 May 1982 that the Soviet government had agreed to pay Swedish costs of $212,000 arising from the incident.

2 Novembre 1981 - (incidente unità navale nucleare) Atlantic: At the Holy Loch naval base in Scotland a Poseidon submarine-launched ballistic missile is dropped 13 to 15 feet as it is moved aboard the submarine tender USS Holland (AS-32) after an error by the crane operator. The fall is arrested by a safety device, but critics suggest there was a serious chance that a conventional explosion could have taken place, dispersing radioactive material. This explosion could have occurred because the Poseidon warhead uses an unstable conventional high explosive called LX-09. Moreover, the Navy is upbraided for not immediately reporting the incident or notifying surrounding communities of possible danger. The U.S. Navy refuses to confirm or deny whether there were nuclear weapons on the missile and states "there was no damage done, no injuries occurred; there was no danger to personnel."

3 Dicembre 1981 - (incidente unità navale nucleare) Atlantic: An arresting wire breaks during the landing of an A-7 Corsair aircraft on the USS John F. Kennedy (CV-67) while operating in the Caribbean Sea, killing two men and injuring three. Four aircraft including the A-7 are damaged.

The next day a Soviet Victor III class nuclear-powered attack submarine is sighted motion less on the surface 282 miles west of Bermuda and 470 miles east of Charleston, South Carolina, by a U.S. P-3 Orion patrol aircraft. U.S. Navy officials believe that while the submarine was following the McCloy, the sonar array caught in the submarine's propeller. There is no indication of leaking radiation, according to a Navy spokesman. On 5 November the submarine is taken under tow by a Soviet salvage ship in the direction of the Cuban port of Cienfuegos. Further observation while the submarine is undertow leads the Navy to believe the damage is relatively minor and relates to the submarine's propeller.

6 Dicembre 1983/Febbraio 1984 - Ciudad Juarez, Messico: dispersione di fonte radiografica compromessa A scrap yard in Ciudad Juarez obtained a used medical teletherapy unit containing about 6,000 1-millimeter pellets of cobalt-60, totalling over 400 curies. On 6 December the source container was deliberately ruptured, scattering pellets throughout the yard. A magnetic loader further dispersed the pellets, many of which ended up in scrap metal converted into steel products around 10 December. Products included steel rebar from a Chihuahua plant, table pedestals from Falcon Products Company in Juarez (some of both items were shipped to the USA), products from a foundry in Torreon, and products from a producer in Guadalajara. The contamination was undetected until 16 January 1984, when a truck carrying contaminated rebar took a wrong turn at the Los Alamos Scientific Laboratory in New Mexico, triggering automatic radiation sensors. Later that day five other trucks carrying contaminated steel were stopped at a border crossing at El Paso, Texas. Efforts to collect contaminated steel progressed over the next few weeks, with about 500 to 931 tons estimated to have entered the USA. In late January contaminated steel was traced to a table manufacturer in St. Louis, Missouri, and 2,500 castings were recalled from 40 states and replaced; most tables were in warehouses but some were removed from restaurants. In February Mexican authorities reported 3 or 4 individuals had received doses of 100 to 450 rem. The U.S. DOE assisted Mexico in aerial surveys 20-26 March which identified 21 contaminated areas. One contaminated pickup truck was found in a residential neighborhood with children playing in it. In Sinaloa Mexican authorities demolished 109 houses built with contaminated rebar. One worker subsequently died of bone cancer, with another 4 injured. A total of at least 10 individuals received significant exposures.

12 Marzo 1984 - (incidente unità navale nucleare) Pacific: The USS Kitty Hawk (CV-63) is struck during night operations by a surfacing Soviet Victor I nuclear-powered attack submarinein the southern Sea of Japan, approximately 100 miles from mainland Japan, while en route to the Yellow Sea. The Kitty Hawk sustains a minor hole below the waterline in an aircraft fuel tank on the starboard side and continues normal operations. The Soviet vessel is observed dead in the water for awhile with a dent across its aft deck. It is assisted by the Soviet Kara class cruiser Petropavlovsk and later is towed by a Soviet salvage vessel to the Vladivostok naval base.U.S. Navy officers say there was no evidence of nuclear leakage from the submarine. The Kitty Hawk had beentaking part in joint U.S.-Korea "Team Spirit 84" exercises. The submarine had been following the Kitty Hawk carrier group with other surface ships for several days. Navy officials claim the carrier's escort ships deliberately broke contact with the submarine after simulating its destruction 15 times to begin a new phase in the exercise where the Kitty Hawk would use deception techniques to lose the trailing Soviet surface ships. The Soviet submarine apparently lost track of the Kitty Hawk and was surfacing to find it when the collision occurred. 21 Marzo 1984 - Giappone.

2 Aprile 1984 - (incidente unità navale nucleare) Atlantic: The Glasgow Herald reports the U.S. Navy at Holy Loch, Scotland admits that the paint on the USS Sam Rayburn (SSBN-635) was mildly radioactive when it returned from patrol in February 1984. The Navy says this is very low-level radioactivity, so low that it could not be detected by a geiger counter. Reports about the radiation had been circulating for a
month, leading to claims that the Sam Rayburn had been in a collision sometime in the fall of 1983 which had caused the ship to leakor become contaminated with radiation. The Navy's statements serve to add to the controversy.

2 Aprile 1984 - (incidente unità navale nucleare) Pacific: At midday in the South China Sea the Soviet carrier Minsk fires eight signal flares at the USS Harold E. Holt (FF-1074) when the latter passes the Minsk's starboard side at a distance of 300 meters after disregarding a request from the Minsk to stand clear.

The submarine is freed only after surfacing and being aided by the Norwegian Coast Guard.

11 Agosto 1984 - (incidente unità navale nucleare) Atlantic: The USS Nathanael Greene (SSBN-636) reportedly loses her propeller in the Irish Sea. The submarine proceeds back to Holy Loch, Scotland, using its secondary propulsion system. Facilities at the U.S. base are unavailable, so the submarine is towed to the near by British submarine base at Faslane, Scotland.

11 Agosto 1984 - (incidente unità navale nucleare) Atlantic: The Royal Navy large fleet tanker HMS Olwen is hit by a storm 700 miles north east of the Falkland Islands, killing two.

14 Agosto 1984 - (incidente unità navale nucleare) Atlantic: An unidentified submarine drags the Britishtrawler Joanne C. around the English Channel for three hours at night after becoming entangled in the trawler's nets eight miles off the U.K.'s south west coast. When the boat radioed for help the Coast Guard told it to cut its nets as the Royal Navy did have a submarine in the area. The Ministry of Defense later says the only Royal Navy submarine in the area was 30 miles away and that no U.S. submarines were nearby, leading to speculation the submarine belongs to the Soviet Union or another Warsaw Pact nation. Yet on 15 September the skipper of the Joanne C. receives compensation of more than 2,000 pounds sterling from the Ministry of Defense, something the Ministry earlier said it would do if a Royal Navy ship was found to be at fault.

18 Agosto 1984 - (incidente unità navale nucleare) Atlantic: A fire reportedly breaks out on board a drydock at the Faslane Royal Navy nuclear submarine base in Scotland while the USS Nathanael Greene (SSBN-636) is in the dock for repairs. A U.K. Ministry of Defense official says the fire was caused by an electrical fault in a capstan motor which ignited a small quantity of canvas a top the motor. He denies the fire threatened the submarine, since it broke out in a sealed compartment some distance from the boat. A spokesman for the U.S. Navy confirms the submarine was not damaged, though he refuses to say whether the ship had nuclear weapons on board.

18 Settembre 1984 - (incidente unità navale nucleare) Pacific: The Japanese shrimping boat Sumiyoshi Maru catches a submarine in its net in the Sea of Japan. The vessel is pulled backward until the 3-centimeter steel wire holding the net is cut. On 20 September a Soviet Golf II class diesel-powered ballistic missile submarine is sighted on the surface with white smoke coming out of its conning tower in the Sea of Japan, 380 miles west of Tokyo. Reports speculate the smoke comes from a fire started by an electrical overload caused by the snagging of the fishing boat's net. Over the next two days the submarine is attended by several Soviet ships, before proceeding toward Vladivostok under its own power on the 23 September.

18 Settembre 1984 - (incidente unità navale nucleare) Atlantic: A Soviet Victor I class nuclear-powered attack submarine is badly damaged in a collision with a Soviet tanker in the Strait of Gibraltar. The submarine reportedly was travelling in the "noise shadow" of the tanker while exiting the Mediterranean Sea. Jane's Defense Weekly notes that the alternating layers of cold and warm water in the narrows of the Strait make it likely for a submarine "to encounter sudden thermal gradients which make her porpoise upwards," and this is thought to be the cause of the accident. The collision rips off the twin-hulled submarine's bow section, exposing the sonar and torpedo tube compartments. The submarine proceeds to the Soviet anchorage at Hammament, Tunisia, for emergency repairs, before returning to its homeport on the Kola peninsula in early October.

21 Settembre 1984 - (incidente unità navale nucleare) Atlantic: The USS Jacksonville (SSN-699) collides with a Navy barge off Norfolk, Virginia, while travelling on the surface. The Jacksonville strikes the barge amidships and is reported to have caused minor damage to her bow.

10 Agosto 1985 Baia di Chazma, Vladivostok, URSS. Un'esplosione devasta il sottomarino sperimentale (progetto 570) atomico sovietico Shkotovo-22: muoiono dieci membri dell’equipaggio esposti alle radiazioni. Furono misurati più di 100.000 Ci di radioattività. I duemila abitanti della baia non furono mai evacuati. Il sottomarino, con i suoi materiali radioattivi, giace in fondo alla baia, sotto diversi metri di sedimenti An explosion occurred during refueling of the submarine K-431 at Chazhma Bay, Vladivostok. The K-431, completed around 1965 as unit K-31, was a Project 675 (Echo II) class submarine with two pressurized water reactors, each 70 MWt capacity and using 20% enriched uranium as fuel. (Note that some sources confuse this submarine with K-314, a Project 671 or Victor I class submarine launched in 1972 and withdrawn from service after a reactor accident in December 1985.) On 10 August 1985, the submarine was being refueled at the Chazhma Bay naval facility near Vladivostock. The submarine had been refueled and the reactor tank lid was being replaced. The lid was laid incorrectly and had to be lifted again with the control rods attached. A beam was supposed to prevent the lid from being lifted too far, but this beam was positioned incorrectly, and the lid with control rods were lifted too far up. At 10:55 AM the starboard reactor became supercritical, resulting in a criticality excursion of about 5x1018 fissions and a thermal/steam explosion. The explosion expelled the new load of fuel, destroyed the machine enclosures, rupturing the submarine's pressure hull and aft bulkhead, and partially destroyed the fuelling shack, with the shack's roof falling 70 meters away in the water. A fire followed which was extinguished after 4 hours, after which assessment of the radioactive contamination began. Most of the radioactive debris fell within 50-100 meters of the submarine, but a cloud of radioactive gas and particulates blew to the northwest across a 6-km stretch of the Dunai Peninsula, missing the town of Shkotovo-22, 1.5 km from the dock. The contaminated forest area was later surveyed as 2 square km in a swath 3.5 km long and 200-650 meters wide. Estimates initial radioactive release was about 2 MCi of noble gases and 5 MCi of other fission products, but most of this was short-lived isotopes; the estimated release inventory one hour after the accident was about 1000 Ci of non-noble fission products. In part because the reactor did not contain spent fuel, the fraction of biologically active isotopes was far smaller than in the case of the Chernobyl reactor accident.
Ten naval personnel were killed (8 officers and 2 enlisted men), probably by the explosion itself and not from radiation injuries. Radiation injuries were observed in 49 people, with 10 developing radiation sickness; the latter figure included mostly firefighters, some of whom sustained doses up to 220 rad external and 400 rem to the thyroid gland. Of the 2,000 involved in cleanup operations, 290 were exposed to high levels of radiation compared to normal standards.
High-level waste gathered during clean-up operations were placed in temporary disposal sites. Due to the rapid decay of most of the reactor products and the cleanup operations, some dockyard facilities were able to resume operations four days later. About two months post-accident the radioactivity in water in the cove was comparable to background levels, and 5-7 months post-accident the radiation levels were considered normal throughout the dock area. The damaged submarine was towed to Pavlovsk Bay and berthed there.

Settembre 1985/6 Gennaio 1986 - Yakima, Washington, USA: incidente radioterapico A defect in the computer program controlling the Therac-25 radiation therapy accelerator resulted in overexposures to patients.

Metà anni '80 -  Scienziati sostengono che i test nucleari in Nevada (circa 240) potrebbero aver provocato negli USA 50.000 casi di cancro alla tiroide, dopo che le mucche da latte e bestiame da allevamento furono contaminati da Iodio radioattivo, passando la radiazione agli uomini attraverso latte e carne. Il governo britannico rivela di aver condotto  esperimenti con radiazioni sulla propria popolazione per almeno 40 anni. Similmente come in America, ignari cittadini sono stati alimentati alimentati con cibo contaminato, intriso di isotopi. Anche in Australia centinaia di cittadini sono stati coinvolti in esperimenti radioattivi che dal dopoguerra sono proseguiti fino al 1960. Acuni esperimenti comportavano l'iniezione di ferro radioattivo negli ovini che venivano in seguito uccisi e dati da mangiare a "volontari"; venne anche iniettato iodio radioattivo a 5 donne incinte per studiare il tracciato cardiaco

29 Gennaio 1986 - (incidente unità navale nucleare) Pacific: The USS Ingersoll (DD-990) makes a heavy landing against the Canadian tug Provider at Esquimalt, British Columbia. Responsibility is charged to an inexperienced tug operator and to brisk winds. Damage to both vessels is minimal.

10 Febbraio 1986 - (incidente unità navale nucleare) Pacific: The USS Willamette (AO-180) collides with the USS Jason(AR-8) 75 miles south west of Pearl Harbor, Hawaii, during a formation steaming exercise, killing one and injuring eight. The collision smashes the Willamette's starboard bow from the rail to below the waterline. A large vertical rupture from deck to waterline on the port side of the Jason forces the ship to be towed back to port.

13 Marzo 1986 - (incidente unità navale nucleare) Atlantic: The USS Nathanael Greene (SSBN-636) runs aground in the Irish Sea, suffering external damage to its ballast tanks and rudder. A spokesman for the U.S. Navy says "There was no effect on the propulsion, no injuries and no damage to the Poseidon nuclear missiles." The submarine initially sails to Holy Loch, Scotland, under its own power for emergency repairs. It then leaves Scotland on 25 April and travels submerged to Charleston, South Carolina. The extent of the damage subsequently leads to a decision to decommission the vessel, partly in order to satisfy SALT II limitations.

21 Marzo/11 Aprile 1986 - Tyler, Texas, USA: incidente radioterapico A defect in the computer program controlling the Therac-25 radiation therapy accelerator resulted in overexposures to two patients. One male patient was overexposed on 21 March, immediately experiencing pain from an estimated 16,500 to 25,000 rad localized dose. Various radiation injuries developed over the next few weeks and the patient died 5 months after the accident. The second patient, also male, received an overexposure to the face on 11 April which produced immediate skin burns. The patient eventually went into a coma and died 1 May of radiation injury to the brain and brain stem. An ETCC physicist eventually identified the nature of the software program that caused this and similar accidents with the Therac-25.

22 Marzo 1986 - (incidente unità navale nucleare) Pacific: The USS Secota (YTM-415) loses power and collides with the stern planes of the Trident submarine USS Georgia (SSBN-729) off Midway Island in the Pacific and sinks, just after completing a personnel transfer.

26 Aprile 1986 - Chernobyl (Ucraina) (scala Ines 7). L'incidente nucleare in assoluto più grave di cui si abbia notizia. Il surriscaldamento provoca la fusione del nucleo del reattore e l'esplosione del vapore radioattivo, che sotto forma di una nube pari a un miliardo di miliardi di Becquerel si disperde nell'aria. Centinaia di migliaia di persone, soprattutto nella vicina Bielorussia, sono costrette a lasciare i territori contaminati. L'intera Europa viene esposta alla nube radioattiva e per milioni di cittadini europei aumenta il rischio di contrarre tumori e leucemia. Non esistono ancora oggi dati definitivi sulle migliaia di vittime ricollegabili alla tragedia. The Chernobyl nuclear power station included four RBMK-1000 reactors at a site 3 km from Prypyat (pop. 45,000) and 15 km from Chernobyl (pop. 12,500). The RBMK-1000 reactor is a graphite-moderated, water-cooled reactor producing 1 MW of power. The design lacks a Western-style containment vessel, instead being based on older Soviet designs optimized for production of plutonium. Unit 4 (housed in the same building as Unit 3) was completed in December 1983 and fully brought on line in March 1984. The early commissioning had left several safety tests undone. In April 1986 Unit 4 was nearly through its first fuel cycle, with the result that a variety of fission products were built up in the core.
On 25 and 26 April 1986 operators were attempting to perform safety tests. On the morning of 26 April they circumvented safety systems to conduct a test at 1:23 AM. The test resulted in a power excursion; without a rapid ability to reinsert control rods the reactor reached 100 times its design thermal output about 1:23:40 AM. A steam explosion at 1:24 AM lifted the 1000-ton upper reactor cover, allowing all the water in the core to escape. This was followed by a second explosion, possibly a hydrogen explosion fueled by reaction of steam from ruptured pipes with zirconium and/or graphite in the reactor core. The second explosion ruptured the roof of the reactor building and expelled about 25% of the reactor core within and beyond the building. One person above the reactor was killed instantly by the explosions. A second person in the reactor building was severely burned by steam; he was found partly buried by debris and died within a few hours. Burning graphite and hot core material ejected by the explosions started about 30 fires, including some on the combustible tar roof of Unit 3. Many plant workers displayed symptoms of radiation sickness within hours of the explosion. In addition to plant workers, firefighters were also exposed significantly while successfully extinguishing fires started on the roof of Unit 3. Total number of people hospitalized was 108 by 6:00 AM and 132 by the end of the first day. Air flow in the damaged reactor building fed a fire in the graphite in the core. About 12 megacuries of radioactivity was released on the first day. Over the following days, attempts to extinguish the fire by dropping material onto the reactor core through the ruptured roof tended to insulate the core, allowing temperatures and emissions to increase after 31 April. The fire was extinguished on 6 May after about 40 megacuries had been released by the fire (in addition to releases on 26 April).
Three individuals died of non-radiation effects: the two killed on 26 April and a third who died of a heart attack. Another 28 individuals (6 firefighters and 22 power plant workers) died of acute radiation sickness, and 238 others survived with acute radiation sickness. Of 22 exposed to 600 to 1,600 rad, 20 died of radiation (one additional death may be due to heart attack associated with the accident); two of these deaths were individuals with total body thermal burns. Survival times for these 20 radiation deaths were 10, 14, 14, 14, 15, 17, 17, 18, 18, 18, 20, 21, 23, 24, 24, 25, 30, 48, 86, and 91 days. Exposures ranging from 400 to 600 rad occurred for 23 individuals, of whom 7 died, all of whom had severe beta burns (covering at least 30% of the body). Survival times for these seven were 16, 18, 21, 23, 32, 34, and 48 days. Exposures of 200 to 400 rad were incurred by 53 individuals, one of whom died 96 days after the accident. Some deaths involved complications of emergency transplants; 13 bone marrow transplants and 6 human embryo liver transplants were performed in the weeks following the accident. Survivors with radiation sickness included about 31 with beta radiation burns. In these cases burns developed one to three weeks after exposure over 1 to 30% or more of the body. A total of about 710 plant workers and emergency workers received doses over 50 rad. Workers who received doses between 25 and 50 rad during response or recovery operations include about 60 workers during the accident, about 2,900 workers during recovery through 1987, and about 16,000 military servicemen. Evacuation of residents under the plume was delayed by the government's unwillingness to publically acknowledge the accident. Throughout Europe many abortions of normal pregnacies were obtained out of fears of radiation from Chernobyl; studies suggest about 100 excess abortions in Italy and 400 excess abortions in Denmark in the months following the accident. Over the following years the principal observed chronic affect has been a significant increase in childhood thyroid cancer, affecting 700-1400 children with 10 deaths reported; these figures are far above background rates, whereas other cancers are not significantly different than background levels.

29 Aprile 1986 - (incidente unità navale nucleare) Atlantic: The USS Atlanta (SSN-712) runs aground in the Strait of Gibraltar, damaging sonar gear and puncturing a ballast tank in the bow section.

30 Settembre 1986 - Il caso Vanunu. A roma viene arrestato dai servizi segreti israeliani, a Roma, il tecnico nucleare Mordechai Vanunu. Vanunu aveva lavorato, dall'agosto 1977 al novembre 1985, nell'impianto nucleare di Dimona nel deserto del Negev, nel sud di Israele, ufficialmente una centrale nucleare di ricerca fornita a Israele dalla Francia alla fine degli anni '50. Dopo una lunga crisi di coscienza ed una fase di crescente impegno politico pacifista negli anni dell'invasione israeliana del Libano, Vanunu lascio' il suo impiego ed intraprese un lungo viaggio all'estero (in Australia e negli USA). Nel settembre del 1986, egli decise di rivelare al "Sunday Times" di Londra tutte le informazioni in suo possesso sull'impianto di Dimona, comprese una sessantina di fotografie che aveva ripreso clandestinamente al suo interno. Sottoposte dal giornale all'esame di alcuni esperti autorevoli (Frank Barnaby e Theodor Taylor, entrambi in passato impegnati nella ricerca e sviluppo di armi nucleari britanniche ed americane), tali informazioni rivelarono che a Dimona, sotto il reattore, un grande edificio sotterraneo a sei piani conteneva tutti gli impianti necessari per "riprocessare" il materiale fissile, separare e purificare il plutonio e costruire ordigni nucleari. Secondo Vanunu, la produzione di plutonio sarebbe stata di circa 40 kg all'anno, parecchie volte superiore a quanto si supponeva in precedenza e sufficiente (secondo l'analisi condotta da Taylor sulle foto di componenti nucleari riprese dal tecnico) per produrre circa otto bombe l'anno. Israele avrebe posseduto cosi' un arsenale dell'ordine di 200 testate, una cifra significativamente piu' alta delle stime (50-100 testate) basate sulla potenza presunta del reattore di Dimona. Vanunu dichiaro' inoltre che Israele produceva bombe a fusione, portando indizi convincenti sulla produzione a Dimona di componenti di deuteruro di litio, un materiale tipico degli ordigni a fusione (si trattava probabilmente di bombe del tipo "boosted", in cui deuterio e trizio vengono posti al centro di una sfera di plutonio, aumentando cosi' la potenza dell'esplosione fino ad alcune centinaia di kton).
Nel marzo del 1988 vi fu il processo: un processo a porte chiuse, da cui fu escluso qualsiasi osservatore esterno, e durante il quale allo stesso Vanunu fu fisicamente impedito di parlare su argomenti "proibiti", che si concluse rapidamente con una condanna a 18 anni di reclusione per spionaggio aggravato e tradimento in tempo di guerra. Due anni dopo, la condanna fu confermata in appello

3/6 Ottobre 1986 – Oceano Atlantico. In seguito ad un incendio il sottomarino K-219, classe OTAN Yankee, affonda nell’Atlantico con 34 testate nucleari a bordo a 644 km ad est delle Bermude.  L'equipaggio, prima dell'affondamento del 6 Ottobre, riesce ad evitare la fusione del nocciolo che, in caso contrario, avrebbe potuto contaminare la costa Est degli Stati Uniti e del Canada. Il relitto a tutt'oggi contiene ancora il reattore nucleare.

3 Ottobre 1986 - (incidente unità navale nucleare) Atlantic: A Soviet Yankee I class nuclear-powered ballistic missile submarine suffers an explosion and fire in one of its missile tubes 480 miles east of Bermuda, killing at least three. General Secretary Gorbachev sends President Reagan a private communication regarding the accident in advance of the public announcement on 4 October, assuring him that there was no danger of nuclear explosion, radioactive contamination, or accidental launching of nuclear missiles. U.S. for cessample the air and water around the submarine and detect no radioactivity. The submarine sinks under tow on 6 October in 18,000f eet of water about 600 miles north east of Bermuda. U.S. sources said that the explosion probably originated in the liquid fuel of one of the missiles.

26 Ottobre 1986 - Un marinaio della portaerei nucleare “US Oriskany”, preso dal panico per l'accensione spontanea di un razzo illumi­nante, lo getta in un loculo che ne contiene altri 650.

31 Ottobre 1986 - (incidente unità navale nucleare) Atlantic: In late October the USS Augusta (SSN-710) is damaged in an under sea collision while on a routine training patrol in the Atlantic. No crew members are injured and the submarine returns to Groton, Connecticut, for $2.7 million worth of repairs byyear's end. Reportedly, according to unnamed U.S. Defense Department sources, it is unclear whether the submarine struck the ocean floor or an underwater object, but there was no risk of the submarine sinking or danger to the nuclear reactor. A Defense Department spokesman refuses to comment on a CBS news report that the submarine "very possibly" collided with a Soviet submarine.

12/29 Settembre 1987 - Goiania, Goias, Brasile: dispersione accidentale di fonte radiografica compromessa con dispersione di polvere di cesio 137 in un'ampia area urbana con gravi conseguenze per i residenti. un apparecchio di radioterapia, abbandonato in un vechhio ospedale,  viene recuperato da robivecchi per la vendita a peso. Il Cesio 137, prodotto attivo dell'apparecchio, si disperde. La gente vi gioca, attirata dal colore blu che emette. 122.800 persone vengono sottoposte a controllo, almeno 4 persone muoiono entro 75 giorni dal ritrovamento più un bambino di 6 anni contaminato con 5,2 mCi, 249 presentano importanti contaminazioni, 120 vengono irradiate, 129 irradiate e contaminate, 49 vengono ospedalizzate (di cui 21 in reparti di cure intensive), 28 casi di ustione, 14 trapianti di midollo e 600 persone, nel 2003, sono ancora sotto sorveglianza medica (livello 5, scala INES)   A radiotherapy unit had been abandoned in a clinic which was being demolished. The unit had a source consisted of 1,375 curies of cesium-137 in the form of cesium chloride salt, sealed within two nested stainless steel containers to form a 5-cm diameter capsule. Two individuals, R.A. and W.P., dismantled the unit and extracted the source, taking it to the home of R.A. Both began vomiting on 13 September; W.P. sought medical treatment on 15 September and was advised to stay home. R.A. opened the source outside his home on 18 September. The unit material was sold to a junkyard owned by D.F., who noticed a blue glow from the source container that night; he and his wife M.F. examined the material closely, also inviting a number of people to view the capsule. On 21 September the source material was removed and distributed among several people, some of whom spread it on their skin. Also that day M.F. became ill and was cared for by her mother M.A., who took contamination to her home on leaving on 23 September. Around 23 September junkyard employees I.S. and A.S. were exposed while further dismantling parts of the unit. D.F.'s brother I.F. took some source material home on 24 September and set it on a table during a meal; several family members, including his 6-year-old daughter L.F., handled the material while eating. On 25 September D.F. sold some unit components to a second junkyard.
With many people ill by 28 September, M.F., assisted by G.S., took the material along with some components recovered from the second junkyard and transported it on a bus to a hospital where she placed it on the desk of Dr. P.M. and stated it was "killing her family." Doctors initially suspected a tropical disease, but one suspected radiation injury. The morning of 29 September a medical physicist, W. F., was contacted; his arrival was delayed because he doubted the readings of his first radiation monitor, but arrived in time to prevent the fire department from throwing the source into a river. The afternoon of 29 September the authorities were alerted and began response, including identification of contaminated areas and treatment of injured people in facilities set up in the city's Olympic stadium. About 112,800 people were examined at the stadium of whom 129 were found to be contaminated; 20 were hospitalized.
By 3 October some injured people had been sent to Rio de Janeiro for treatment, while others were treated in a special wing of the Goiania General Hospital. Four people died in the acute phase: M.F. and L. F. died 23 October, with respective doses of 570 and 600 rad, respectively; I.S. died 27 October (dose 450 rad); A.S. died 28 October (dose 530 rad). A fifth person, D. F. (dose 700 rad) was hospitalized in May 1994 and subsequently died of liver failure related to his radiation injury. Others exposed included M.A. (430 rad), G.S. (300 rad), and Dr. P.M. (130 rad). W.P. suffered radiation injury to his hand, and R.A. and W.P. both suffered radiation sickness. In addition to the five who died, 23 suffered localized radiation burns, several requiring amputation of fingers. The 23 injured survivors included 9 showing bone marrow depression of whom 3 displayed acute radiation sickness. During hospitalization many patients suffered depression and other emotional problems.

1990 - Sasolburg, Sud Africa: fonte compromessa A cobalt-60 industrial radiography source was left behind following radiography work, with the operator failing to realize the source was left behind. Six people handled the source for 5 to 20 minutes, three of whom received whole body doses of 10 to 55 rad. One person had to have the right hand amputated above the wrist. Three others suffered skin injuries on the fingers.

Febbraio 1990 - Azerbaijan: Azerbeijani rebels unsuccessfully attacked a Soviet military depot near Baku where nuclear weapons are stored; Soviet troops were sent to secure the base

29 Marzo 1990 - USA: incidenti da fluoroscopio A male patient underwent several procedures using fluoroscopy (two coronary angiographies, a coronary angioplasty, and a coronary artery by-pass graft) in the same day. About one month later the skin became reddened on his back, eventually developing a small ulcerated area. The localized dose probably exceeded 2000 rads.

21 Giugno 1990 - Soreq, Israele: incidente in un impianto radioattivo commerciale The accident occurred at a commerical irradiator, in which packages are automatically moved through an area exposed to a cobalt-60 source. Several maintenance problems contributed to the accident, which began when packages became jammed in the irradiation area. An operator choose to reject the radiation warning indicator in favor of an indicator erroneously showing the cobalt source to be in safe (shielded) mode. He overrode safety features to enter the irradiation room; after a short time he felt burning in his eyes and a headache. He then left the room and contacted his supervisor, and shortly after began vomiting; he arrived at a hospital 8 hours after exposure. The worker received a whole body dose between 1000 and 2000 rads and died 36 days later of multiple organ failure, despite efforts including a bone marrow transplant.

24 Giugno 1990 - Chernobyl, Ucraina: evento sub critico di moltiplicazione di neuroni nella stanza 304/3 del reattore danneggiato

25 Giugno 1990 - Shanghai, Cina: incidente da irradiazione An accident occurred at an industrial irradiator which used a 23,000-curie cobalt-60 source for sterilization of traditional Chinese medicines. Access to the irradiation room was via a double door which had safety interlocks to prevent enter while the source was unshielded. However, the motor on one door had previously failed, putting the door out of commission, and a power failure disabled the interlock on the second door. One worker additionally violated procedure by turning on lights in the room without turning on electricity of the source system. During this period 7 workers entered the room to arrange product boxes for irradiation, with exposure times up to 40 minutes. A metal shroud prevented them from seeing that the source was exposed. One worker had nausea within 20 minutes, and several were vomiting within 2 hours. Several were hospitalized the following day. Two workers sustained exposures of 1,200 rad and 1,100 rad and were given bone marrow transplants from relatives, but both died (25 and 90 days after exposure, respectively). Exposures to the other 5 workers were at least 200 rad.

Luglio 1990 - Chernobyl, Ucraina: evento sub critico di moltiplicazione di neuroni nella stanza 304/3 del reattore danneggiato

10/20 Dicembre 1990 - Zarragosa, Spagna: incidente radioterapico An error occurred in the maintenance and calibration of a linear accelerator used for clinical radiotherapy; combined with procedural violations, overdosages of 200-700% occurred. The accelerator is related to the Therac-25 involved in several accidents in the United States and Canada. A total of 27 patients were overexposed during treatments for tumors between 10 and 20 December. Signs of radiation injury were observed on 26 December, and the first death occurred possibly shortly thereafter. By 28 February 1991 three patients had died, and an additional 7 died by 31 March 1991. Spainish authorities were reportly hesitant to release details of the accident, but sought foreign assistance in early 1991. A total of 18 eventually died as a result of radiation overexposures. The remaining patients all suffered major disabilities as a result.

14 Dicembre 1990 -Calabria, Italia. Spiaggiamento della motonave Rosso in Calabria, nella zona di Formiciche. Si sospetta che l'incidente sia avvenuto in seguito ad un fallito affondamento di rifiuti tossici radioattivi.
