Rem (Roentgen Equivalent Man) is the derived unit of any of the quantities expressed as the radiation absorbed dose (rad) equivalent.The dose equivalent in rems is equal to the radiation absorbed dose in rads multiplied by the quality factor. Units for dose equivalent are the roentgen equivalent man and sievert , and biological dose equivalents are commonly measured in 1/1000th of a rem (known as a millirem or mrem). For practical purposes, 1 R (exposure) = 1 rad (absorbed dose) = 1 rem or 1000 mrem (dose equivalent). 1 sievert = 100 rem 1 becquerel (Bq) = 1 count per second (cps) 1 curie = 37,000,000,000 becquerel = 37 Gigabecquerels (GBq) For x-rays and gamma rays, 1 rad = 1 rem = 10 mSv For neutrons, 1 rad = 5 to 20 rem (depending on energy level) = 50-200 mSv For alpha radiation (helium-4 nuclei), 1 rad = 20 rem = 200 mSv This is a conversion chart for rem (Dose equivalent radiation).

Rem The rem is a unit of absorbed dose equivalent.

The millirem is a unit of measurement of radiation absorbed dose Millirem is the special unit of any of the quantities expressed as dose equivalent in thousandths of a rem. The dose equivalent in rems is equal to the absorbed dose in rads multiplied by the quality factor (1 rem=0.01 sievert) 1.

(A milliRem is 1/1000th of a Rem. According to McGraw-Hill's Dictionary of Scientific and Technical Terms, a Rem is a unit of ionizing radiation equal to the amount that produces the same damage to humans as one roentgen of high-voltage x-rays. The name is derived from "Roentgen equivalent man."

A radiation source The rem is the most common unit used to measure health effects of radiation. The absorbed dose of specific types of radiation is multiplied by a "quality factor" to arrive at the dose equivalent.

30 May 2018 A millirem or mrem is 1/1000 of a rem, a measure of the biological effect of Units in the metric system are the Gray (Gy) and the Sievert (Sv).

1 sievert (Sv) = 100 rem. 1 … Rem, unit of radiation dosage (such as from X rays) applied to humans. Derived from the phrase Roentgen equivalent man, the rem is now defined as the dosage in rads that will cause the same amount of biological injury as one rad of X rays or gamma rays. In radiation protection, the rem (an abbreviation for Roentgen Equivalent Man) is the non-SI unit of the equivalent dose, which is used predominantly in the USA.The rem represents the equivalent biological effect of the deposit of one hundred ergs of gamma rays energy in a kilogram of human tissue.The rem is not derived from the unit of exposure, the roentgen.
