Surviving the highest known radiation dose in any human 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.

Harold Ralph McCluskey (July 12, 1912 – August 17, 1987) was a chemical operations technician at the Hanford Plutonium Finishing Plant located in Washington State; he is known for having survived exposure to the highest dose of radiation from americium ever recorded. [2] He became known as the "Atomic Man". [3] [4] [5]
The concept of radiation hormesis is relevant to this table – radiation hormesis is a hypothesis stating that the effects of a given acute dose may differ from the effects of an equal fractionated dose. Thus 100 mSv is considered twice in the table below – once as received over a 5-year period, and once as an acute dose, received over a ...
The highest annual personal dose was 5.7 mSv in 2015 and 6.0 mSv in 2016. [194] The collective dose for 2015 was about 76 person-Sv. This means that flight personnel are among the occupational groups in Germany with the highest radiation exposure in terms of collective dose and average annual dose. [195]
The highest level of purely natural radiation ever recorded on the Earth's surface was 90 μGy/h on a Brazilian black beach (areia preta in Portuguese) composed of monazite. [25] This rate would convert to 0.8 Gy/a for year-round continuous exposure, but in fact the levels vary seasonally and are much lower in the nearest residences.
Highest dose received by a worker responding to the Fukushima emergency [52] [a] 1: Sv: Maximum allowed radiation exposure for NASA astronauts over their career [33] 4–5: Sv: Dose required to kill a human with a 50% risk within 30 days (LD 50 /30), if the dose is received over a very short duration [53] [32] 5: Sv:
Capt. Lacie "Sonic" Hester, an F-15E instructor weapons systems officer, is the first Air Force woman to receive the Silver Star and only the 10th female service member ever to receive the award.
There is a small increase in the dose, due to naturally occurring gamma radiation, around small particles of high atomic number materials in the human body caused by the photoelectric effect. [24] By comparison, the radiation dose from chest radiography (about 0.06 mSv) is a fraction of the annual naturally occurring background radiation dose. [25]
