Stevens died of heart disease some 20 years later, having accumulated an effective radiation dose of 64 Sv (6400 rem) over that period, i.e. an average of 3 Sv per year or 350 μSv/h. The current annual permitted dose for a radiation worker in the United States is 0.05 Sv (or 5 rem), i.e. an average of 5.7 μSv/h. [3]
All three of the experimental reactor crew died when the reactor went prompt critical and the core explosively vaporized. 3 Samut Prakan radiation accident: 2000 February Three deaths and ten injuries resulted when a radiation-therapy unit was dismantled. [20] 2 Tokaimura nuclear accident, Japan: 1999, September 30
Louis Harold Gray FRS (10 November 1905 – 9 July 1965) was an English physicist who worked mainly on the effects of radiation on biological systems. He was one of the earliest contributors of the field of radiobiology. [6]
Douglas Harris Crofut (November 6, 1942 – July 27, 1981) was an American radiographer who inspected oil and natural gas pipelines. He died in intensive care as a result of radiation burns and radiation poisoning.
An inspection of Coblentz's bibliography shows that from about 1930 his research turned more toward measurements involving the ultraviolet (UV) region and away from infrared work. Much of this research had a distinctly bio-medical slant, such as his investigations of ultraviolet therapy (1938) and the production of skin cancer by UV exposure ...
Scientist Harry Daghlian suffered fatal radiation poisoning and died 25 days later after accidentally dropping a tungsten carbide brick onto a sphere of plutonium, which was later (see next entry) nicknamed the demon core. The brick acted as a neutron reflector, bringing the mass to criticality. This was the first known criticality accident ...

Of the remaining thieves, two died and three received radiation injuries. [36] 1999 – Kingisepp, Leningrad Oblast, Russia – The radioisotope core of a radio thermal generator was recovered at a bus station in Kingisepp. Radiation levels at the surface of the source were 1,000 rad (10 Gy)/hour.
