Background radiation is from naturally radioactive materials and cosmic radiation from space. [5] People are exposed to this radiation from the environment continuously, with an annual dose of about 3 mSv. [5] Radon gas is a radioactive chemical element that is the largest source of background radiation, about 2mSv per year. [17]
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.

Radiation poisoning, also called "radiation sickness" or a "creeping dose", is a form of damage to organ tissue due to excessive exposure to ionizing radiation. The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long-term exposure to low-level radiation.
The bill by Sens. Josh Hawley, R-Mo., and Ben Ray Lujan, D-N.M., would expand the Radiation Exposure Compensation Act to include more people who believe their illnesses were caused by that exposure.
These were distributed and used in multiple cities across Mexico and the United States and exposed an estimated four thousand people to radiation. [85] 1985 to 1987: The Therac-25 accidents. A radiation therapy machine was involved in six accidents, in which patients were exposed to massive overdoses of radiation. 4 fatalities, 2 injuries. [86]
83 people were injured due to uneven cooling of the reactor core, resulting in fuel element failures and multiple ruptures. [12] 8 Soviet submarine K-19 reactor accident 1961, July 4 More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably.
[105] [106] On 15 March, TEPCO decided to work with a skeleton crew (in the media called the Fukushima 50) in order to minimize the number of people exposed to radiation. [107] On 17 March, IAEA reported 17 persons to have suffered deposition of radioactive material on their face; the levels of exposure were too low to warrant hospital ...
All microwaves are built to seal these waves and automatically shut off when the door is opened, preventing exposure. Plus, unlike ionized radiation — which can put people at risk for developing ...
