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. Formerly poorly defined, the rem was

2015-07-08 · Although rad does not depend on the type of radiation deposited on a body, the impact of that energy on a biological unit is dependent on the type of radiation. The rem is a dose equivalent and accounts for the difference in biological impacts based on particle size (the SI equivalent is sievert [Sv], where 100 rem = 1 Sv).

The dose in rem equals the dose in rad multiplied by the quality factor (Q). 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. The units of measure for radioactivity are the curie (Ci) and becquerel (Bq).

A radiation weighting factor (W R) is used to modify the absorbed dose amount to account for the greater damage inflicted by some forms of ionizing radiation (rad × W R = equivalent dose [rem]) a. W R takes into account linear energy transfer (LET), which is the amount of energy transferred by ionizing radiation per unit length of tissue traveled

See also rem. (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." The roentgen equivalent for man (rem) is the unit for radiation damage that is used most frequently in medicine (1 rem = 1 Sv). Note that the tissue damage units (rem or Sv) includes the energy of the radiation dose (rad or Gy) along with a biological factor referred to as the RBE (for relative biological effectiveness ) that is an approximate measure of the relative damage done by the radiation. Source: The Canadian Radiation Protection Regulations, Schedule 2 (SOR/2000-203). Equivalent dose is often referred to simply as "dose" in every day use of radiation terminology. The old unit of "dose equivalent" or "dose" was rem.

The rem (an acronym for roentgen equivalent man) was the cgs unit of effective dose and was officially replaced by the sievert many years ago.. One rem was a large quantity of radiation, and therefore for practical day to day use the millirem (mrem), representing one-thousandth of a rem, was usually employed. material or tissue.
