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.

Displayed background gamma radiation level is 9.8 μR/h (0.82 mSv/a) This is very close to the world average background radiation of 0.87 mSv/a from cosmic and terrestrial sources. Cloud chambers used by early researchers first detected cosmic rays and other background radiation.

Map of contaminated areas around the plant (22 March – 3 April). Map of detected radioactivity as of April 2011 Map of detected radioactivity as of March 2012 Fukushima dose rate comparison to other incidents and standards, with graph of recorded radiation levels and specific accident events from 11 to 30 March in 2011.
Global map of global horizontal radiation [5] Global Map of Direct Normal Radiation [5]. There are several measured types of solar irradiance. Total solar irradiance (TSI) is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere.
Two hundred plus fatalities and this figure is a conservative estimate; 270,000 people were exposed to dangerous radiation levels. Over thirty small communities had been removed from Soviet maps between 1958 and 1991. [13] (INES level 6). [14] July 4, 1961 – Soviet submarine K-19 accident. Eight fatalities and more than 30 people were over ...
However, the background radiation from cosmic rays increases with altitude, from 0.3 mSv per year for sea-level areas to 1.0 mSv per year for higher-altitude cities, raising cosmic radiation exposure to a quarter of total background radiation exposure for populations of said cities.
The Oh-My-God particle was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, United States. [1] [2] [3] As of 2023, it is the highest-energy cosmic ray ever observed. [4]
