US Department of Energy 2010 dose chart in sieverts for a variety of situations and applications [32] Various doses of radiation in sieverts, ranging from trivial to lethal, expressed as comparative areas Comparison of radiation doses – includes the amount detected on the trip from Earth to Mars by the RAD on the MSL (2011–2013). [33] [34 ...
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. [1]
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.
Equivalent dose and effective dose are measured in sieverts (Sv). [4] Dose quantities used in radiation protection. For example, suppose a person's small intestine and stomach are both exposed to radiation separately. [2] The absorbed dose of small intestine is 100 mSv and the absorbed dose of stomach is 70 mSv.
The collective radiation background dose for natural sources in Europe is about 500,000 man-Sieverts per year. The total dose from Chernobyl is estimated at 80,000 man-sieverts, or roughly 1/6 as much. [1] However, some individuals, particularly in areas adjacent the reactor, received massively higher doses.

The commitment period is taken to be 50 years for adults, and to age 70 years for children. [3] This refers specifically to the dose to the whole body, in the similar way to external effective dose.
A cleaning company has been fined $171,000 after federal investigators found 11 children working a "dangerous" overnight shift at a meat processing plant in Iowa.
