The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).
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 ...
He continued going to the Moscow radiation clinic twice a year for examinations and to meet with other nuclear accident victims. He was described as "a poster boy for Soviet and Russian radiation medicine". [1] In 1996, Bugorski applied unsuccessfully for disability status to receive free epilepsy medication. [8]
The radiation source in the Goiânia accident was a small capsule containing about 93 grams (3.3 oz) of highly radioactive caesium chloride (a caesium salt made with a radioisotope, caesium-137) encased in a shielding canister made of lead and steel. The source was positioned in a container of the wheel type, where the wheel turns inside the ...
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.

Niels Ryberg Finsen (15 December 1860 – 24 September 1904) was a physician and scientist.In 1903, he was awarded the Nobel Prize in Medicine and Physiology "in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation, whereby he has opened a new avenue for medical science."
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]
Kanzius RF Therapy is an experimental cancer therapy that employs a combination of either gold or carbon nanoparticles and radio waves. [2] [8] [9]The specific absorption rate for radio waves by living tissue in the proposed wavelengths and intensity levels is very low.
