The 2,772 MWt Babcock & Wilcox pressurized water reactor (913 MWe) achieved initial criticality on September 16, 1974, and entered commercial operation on April 17, 1975. [3] On March 20, 1978, a power supply failure for the plant's non-nuclear instrumentation system led to steam generator dryout (ref NRC LER 312/78-001).
More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably. Emergency repairs ordered by the captain successfully cooled the reactor and avoided meltdown, but exposed the workers to high levels of radiation. [17] 8 Radiation accident in Morocco: 1984 March
1985 to 1987 – The Therac-25 was a radiation therapy machine produced by Atomic Energy of Canada Limited (AECL). It is known to be responsible for six accidents between 1985 and 1987, in which patients were given massive overdoses of radiation, which were in some cases on the order of hundreds of grays. Three patients died as a result of the ...
The Chernobyl reactor didn't just expel aerosol particles, fuel particles, and radioactive gases, but there was an additional expulsion of Uranium fuel fused together with radionuclides. [10] These hot particles could spread for thousands of Kilometers and could produce concentrated substances in the form of raindrops known as Liquid hot ...
After revelations that radioactive waste may be buried under two Bay Area parks, the cities of Albany and Berkeley submitted testing plans. Albany's was approved; Berkeley's was deemed insufficient.
Radiation fluctuated widely on the site after the tsunami and often correlated to fires and explosions on site. Radiation dose rates at one location between reactor units 3 and 4 was measured at 400 mSv/h at 10:22 JST, 13 March, causing experts to urge rapid rotation of emergency crews as a method of limiting exposure to radiation.

David Charles Hahn (October 30, 1976 – September 27, 2016), sometimes called the "Radioactive Boy Scout" and the "Nuclear Boy Scout" was an American nuclear radiation enthusiast who built a homemade neutron source at the age of seventeen.
An activist invester has taken interest in pharma giant Pfizer, which despite becoming a household name during the pandemic has struggled to move its stock.
