Sievert

Definition 1

The international system (SI) unit for radiation dose equivalent equal to 1 Joule/kilogram. 1 sievert = 100 rem. (NCI Thesaurus)

Definition 2

A unit of equivalent radiation dose. One Sv is received when the actual absorbed dose of ionizing radiation, after being multiplied by the dimensionless factors Q (the relative biological efficiency or quality factor) and N (the product of any other multiplying factors that takes into account the distribution of energy throughout the dose), is one joule per kilogram. In this scheme, the relationship between the absorbed dose of radiation D and the dose equivalent H is, therefore, given by H = QND. Both Q and N are stipulated by the International Commission on Radiological Protection. One Sv is equal to 100 rem. (NCI Thesaurus/CDISC)
