rapid eye movements (see under sleep ).

rem

(rem) r oentgen-e quivalent–m an: the amount of any ionizing radiation that has the same biological effectiveness as 1 rad of x-rays; 1 rem = 1 rad × RBE (relative biological effectiveness).

rem

(rĕm)
n.
1. The amount of ionizing radiation required to produce the same biological effect as one rad of high-penetration x-rays.
2. A unit for measuring absorbed doses of radiation, equivalent to one roentgen of x-rays or gamma rays.

rem

[rem, är′ē′em′]
abbreviation for roentgen equivalent man, a dose of ionizing radiation that produces in humans the same effect as one roentgen of x-radiation or gamma radiation. See also sievert.

REM

abbreviation for rapid eye movement. See sleep.

rem

Roentgen-equivalent in man Radiation physics The traditional unit of equivalent dose/unit of absorbed radiation, ± equal to a rad or 0.01 Seivert–Sv, the unit that replaces the rem–1 Sv = 100 rem. See Gray, Rad, Sievert.

Abbreviation for roentgen-equivalent-man.

rem (roentgen-equivalent-man),

n a unit of absorbed radiation dose adjusted for biologic effects equivalent to 1 rad of 250 kV roentgen rays (dental and cephalometric roentgen rays require less than 100 kV).

rem

acronym for roentgen equivalent man; the amount of any ionizing radiation which has the same biological effect as 1 rad of x-rays; 1 rem = 1 rad × RBE (relative biological effectiveness). Now replaced by the sievert (Sv) SI unit. 1 Sv = 100 rem.
