0.1141 mrem/h = 1,000 mrem/yr. The International Commission on Radiological Protection (ICRP) once adopted fixed conversion for occupational exposure, although these have not appeared in recent documents: [6] 8 h = 1 day 40 h = 1 week 50 week = 1 yr. Therefore, for occupation exposures of that time period, 1 mrem/h = 2,000 mrem/yr 0.5 mrem/h ...
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.
The origins of the concept are uncertain, but one early mention can be found on the RadSafe nuclear safety mailing list in 1995, where Gary Mansfield of the Lawrence Livermore National Laboratory mentions that he has found the "banana equivalent dose" to be "very useful in attempting to explain infinitesimal doses (and corresponding infinitesimal risks) to members of the public".

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. Chernobyl's radiation was detectable across Western Europe. Average doses received ranged from 0.02 mrem to 38 mrem (portions of Germany). [1]
The 2000 UNSCEAR estimate for worldwide average natural background radiation dose is 2.4 mSv (240 mrem), with a range from 1 to 13 mSv. A small area in India as high as 30 mSv (3 rem). A small area in India as high as 30 mSv (3 rem).
The consumer healthcare company is recalling the cough syrup, sold under the brand name "Robitussin Honey CF Max Day Adult" in 4-ounce and 8-ounce doses, along with its 8-ounce night-time version.
Various internet sources have deduced that overall we make an eye-popping 35,000 choices per day. Of this number, 227 choices daily are made on just food alone according to researchers at Cornell ...
The roentgen or röntgen (/ ˈ r ɛ n t ɡ ə n,-dʒ ə n, ˈ r ʌ n t-/; [2] symbol R) is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air (statcoulomb per kilogram).
