Ģ49 people received a large radiation dose from a lost radiotherapy source. Five people suffered radiation burns and died at least one other person suffered acute radiation sickness, and twelve others were exposed. Lost radiation source, Baku, Azerbaijan, USSRĪ caesium-137 orphan source was carried by an individual in a clothes pocket, exposing several individuals. Īt least 8 people died when an iridium-192 source used to radiograph welds became separated from its shielded container.Īn accident involving yttrium-90 in nuclear medicine therapy caused 7 deaths. Emergency repairs ordered by the captain successfully cooled the reactor and avoided meltdown, but exposed the workers to high levels of radiation. More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably. Ĩ3 people were injured due to uneven cooling of the reactor core, resulting in fuel element failures and multiple ruptures. Ĩ8 injuries resulting in 10 fatalities from cobalt-60 source due to incorrect calibration of a teletherapy unit. Reactor lid and control rods were lifted too far while adjusting position, resulting in criticality excursion. : 299, 303Ĭancer patients receiving radiotherapy 11 fatalities and 27 patients were injured. ġ14 patients received an overdose of radiation from a cobalt-60 source that was being used for radiotherapy. Patients receiving treatment for prostate cancer and cancer of the cervix receive lethal doses of radiation. The overall death count as a result of the accident is disputed. It has been suggested that 2,202 died as a result of the stresses of evacuation. In 2018, 1 cancer death of a man who worked at the plant at the time of the accident was attributed to radiation exposure by a Japanese government panel. More recent academic research carried out in 2007 estimated that 100 to 240 deaths were caused by the radiation leak. There are varying estimates of increased mortality over subsequent decades (see Deaths due to the disaster).Ī 1988 UK government estimate stated that there would be around 100 deaths by 2007 as a result of exposure to radioactive material. Death count unknown, estimates range from 50 to more than 9,000.Īt least 78 are believed to have been directly killed by the disaster (31 due to the explosion, 28 due to radioactivity during cleanup, and an additional 19 for the same reason by 2004). There have been several nuclear and radiation accidents involving fatalities, including nuclear power plant accidents, nuclear submarine accidents, and radiotherapy incidents.Īn improperly stored underground tank of high-level radioactive waste exploded.
