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.
Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
The rem has been defined since 1976 as equal to 0.01 sievert, which is the more commonly used SI unit outside the United States. Earlier definitions going back to 1945 were derived from the roentgen unit, which was named after Wilhelm Röntgen, a German scientist who discovered X-rays. The unit name is misleading, since 1 roentgen actually ...
ERR = excess relative risk per sievert; EAR = excess additive risk per sievert; M c (a) = the sex- and age-specific cancer mortality rate in the U.S. population; F = the tissue-weighted fluence; L = the LET; v = the fractional division between the assumption of the multiplicative and additive risk transfer models.
mSv = millisievert (1/1000 of a sievert), MSv = megasievert (a million sievert). This follows the convention for metric prefixes (similar to mW, milliwatt vs MW, megawatt). In the case of the Sievert, 1 sievert is already a huge amount of radiation likely to kill you, so a megasievert is a ridiculous amount.
Geiger-Müller counter with dual counts/dose rate display measuring a "point source". The dose per count is known for this specific instrument by calibration. The count rates of cps and cpm are generally accepted and convenient practical rate measurements.
Sieverts (symbol: Sv) is plural for the SI unit of equivalent absorbed radiation dose . Sieverts may also refer to: . Adolf Sieverts (1874–1947), German chemist . Sieverts's law, rule to predict the solubility of gases in metals
