Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever, was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human.[1] On May 14, 1945, he was injected with 131 kBq (3.55 μCi) of plutonium without his knowledge because it was erroneously believed that he had a terminal disease.[2]

Plutonium remained present in his body for the remainder of his life, the amount decaying slowly through radioactive decay and biological elimination. 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]
