Definitions for "EQUIVALENT DOSE"
Keywords:  sievert, rem, icrp, dose, rads
This is the measure that indicates the degree of biological damage caused by radiation. Equivalent dose is measured in rems. [Back to Module 2
(previously "Dose Equivalent") The International Commission for Radiological Protection's term (starting with ICRP Publication 60) for the product of the amount of energy absorbed per mass of tissue (joules per kilogram) times the quality factor for the type of radiation imparting the energy. The unit used for equivalent dose is the sievert (Sv). The unit used previously for dose equivalent was the rem. (1 rem = 0.01Sv)
A quantity developed for purposes of radiation protection and assessing risks to human health in general terms, defined as the average absorbed dose in an organ or tissue modified by the radiation weighting factor for the type, and sometimes energy, of the radiation causing the dose, as defined in ICRP (1991a). Supersedes average dose equivalent, as defined in ICRP (1977). The SI unit of equivalent dose is the joule per kilogram (J kg−1), and its special name is the sievert (Sv). In conventional units used in this report, equivalent dose is given in rem; 1 rem = 0.01 Sv.
