Na proteção contra radiação, o rem (uma abreviação de Roentgen Equivalent Man) é a unidade não SI da dose equivalente, usada predominantemente nos EUA. O rem representa o efeito biológico equivalente ao depósito de cem ergs (um rad) de energia de raios gama em um quilograma de tecido humano.

The rem is a measurement of the biological effect of that absorbed radiation. For general purposes most physicistsagree that the Roentgen, Rad and Rem may be considered equivalent. System International (SI) Units The System International(S.I. unit) unit s for radiation measurements are“gray” (Gy) and “sivert” (Sv) Radiation increases the risk of cancer and other stochastic effects at any dose. The ICRP maintains a model of these risks as a function of absorbed dose and other factors. That model calculates an effective radiation dose, measured units of rem, which is more representative of the stochastic risk.

· How is the curie defined? · A sample of radon gas has an activity of 140.0 mCi. · A 28 Mar 2011 Why don't all radiation experts just use the same unit? of radiation can be expressed in either SI units (sieverts) or U.S. customary units (rem). For equivalent dose, the unit corresponding to rads is the rem (roentgen equivalent man). If the absorbed dose is in grays then the unit for dose equivalent is Curie is the unit for radioactivity in the. U.S. Rem (Roentgen equivalent in man) unit of exposure, energy deposition in air, specific to X-rays.

What is a person's annual exposure to radioactivity and radiation? Table 15.3 “Average Annual Radiation Radiation Measurements.

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.

REM (Roentgen Equivalent Man) A unit in the traditional system of units that measures the effects of ionizing radiation on humans. The rem has been replaced by the Sievert in the SI system of units (1 Sievert = 100 rem). www.hps.org For diagnostic x-ray exposure, a rem is approximately equivalent to a rad The SI unit of E is the sievert (Sv) or but rem (roentgen equivalent man) is still commonly used (1 Sv = 100 rem). Unit of sievert was named after the Swedish scientist Rolf Sievert, who did a lot of the early work on dosimetry in radiation therapy. Units of effective dose. Sievert. The sievert is a derived unit of equivalent dose and effective The difference between the rad and rem is that the rad is a measurement of the radiation absorbed by the material or tissue.

SI unit of absorbed dose equivalent is Sievert. 1 Sievert (Sv) = 100 rems Rem = Rads x Quality factor B/ c the quality factor for Xray is 1 , therefore diagnostic energy levels. An average person receives around 400 mrems of radiation each year.

Radiation exposure is measured primarily in Rem (in the US) and the Sievert (SI unit), and is a measure of the radioactive dose absorbed relative to its possible
