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.

Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.
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 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.
If the body has been subject to uniform irradiation, the effective dose equals the whole body equivalent dose, and only the radiation weighting factor W R is used. But if there is partial or non-uniform body irradiation the calculation must take account of the individual organ doses received, because the sensitivity of each organ to irradiation ...
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.
Radiant intensity is used to characterize the emission of radiation by an antenna: [2], = (), where E e is the irradiance of the antenna;; r is the distance from the antenna.; Unlike power density, radiant intensity does not depend on distance: because radiant intensity is defined as the power through a solid angle, the decreasing power density over distance due to the inverse-square law is ...
