Röntgen equivalent man

The Röntgen equivalent in man or rem (symbol rem) is a unit of radiationdose. It is the product of the absorbed dose in röntgens(R) and the biological efficiency of the radiation. More precisely, assuming a radiation weighting factorrW=1, 1 rem equals 1.07185 röntgen. The conversion factor has been readjusted from 1 to 1.07185 so that 100 rem equal 1 sievert; the sievert is the recommended (and in many cases legally prescribed) SI derived unit.

A millirem (abbr. mrem) is one thousandth of a rem.
