WebMar 20, 2024 · Units for dose equivalent are the roentgen equivalent man ( rem) and sievert ( Sv ), 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). WebQuantities measured in rem are designed to represent the stochastic biological risk of ionizing radiation, which is primarily radiation-induced cancer. These quantities are derived from absorbed dose, which in the CGS system has the unit rad.
