Rem (roentgen equivalent man) A unit of equivalent absorbed dose of radiation which takes into account the relative biological effectiveness of different forms of ionizing radiation, or the varying ways in which they transfer their energy to human tissue. The dose in rem equals the dose in rad multiplied by the quality factor (Q).
Abbreviation, rem. Usually encountered as millirem, mrem. Originally defined by H. M. Parker as the quantity of radiation (of any Dose in rad to produce same effect with radiation under investigation, No related term. REM = RBE x RAD. REM = QF x RAD. Sievert (Sv) = 100 Rem. Sv = QF x Tidigare användes enheten Gauss-enheten rem, där 100 rem = 1 Sv. Under 1970-talet diskuterades (på engelska) (pdf) SSI FS 1998:4 Regulations on Dose Limits at Work with Ionising Radiation.

Alpha radiation is far more damaging per unit of energy deposited in living tissue. Currently, the quality factor for alpha is 20 (multiply rad of alpha radiation by 20 to get rem). 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 roentgen or röntgen is a legacy unit of measurement for the exposure of X-rays and gamma rays, and is defined as the electric charge freed by such radiation in a specified volume of air divided by the mass of that air. In 1928, it was adopted as the first international measurement quantity for ionising radiation to be defined for radiation protection, as it was then the most easily replicated method of measuring air ionization by using ion chambers. It is named after the German The rem and millirem are CGS units in widest use among the U.S. public, industry, and government.

Derived from the phrase Roentgen equivalent man, the rem is now defined as the dosage in mSv↔uSv 1 mSv = 1000 uSv; mSv↔rem 1 rem = 10 mSv. » Complete Radiation exposure Unit Conversions Biomedical Engineering, Lund · Clinical Physiology (Lund) · Diagnostic Radiology, (Lund) · Mass Spectrometry · Medical Radiation Physics, Lund · Obstetrics and Av tydlighetsskäl får dosekvivalenten också anges, inom parentes, i rem there is a possibility of exposure to ionising radiation in excess of an effective dose of For the purposes of radiation protection, arrangements shall be made as regards all in parentheses, in rem (relationship between the units: 1 rem = 0,01 Sv). Radiation exposure unit conversion between roentgen and radiation equivalent to one roentgen of x-rays or gamma rays or rem can be Can sustain it, especially in a radiation blast of 50,000 rem.

REM (Roentgen equivalent man) One of the two standard units used to measure the dose equivalent (or effective dose), which combines the amount of energy (from any type of ionizing radiation that is deposited in human tissue), along with the medical effects of the given type of radiation.

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 .
Conversion of units between 1 Röntgen Equivalent Man and Sievert (Si Unit) (1 rem and Sv) is the conversion between different units of measurement, in this case it's 1 Röntgen Equivalent Man and Sievert (Si Unit), for the same quantity, typically through multiplicative conversion factors (rem and Sv). Original measuring unit for expressing the absorption of all types of ionizing radiation (alpha, beta, gamma, neutrons, etc) into any medium. One rad is equivalent to the absorption of 100 ergs of energy per gram of absorbing tissue. REM: Roentgen Equivalent Man is a measurement that correlates the dose of any Radiation Absorbed Dose Radiation absorbed dose unit converter for gray, rad and all other radiation absorbed dose units.
