Sievert
[Sievert (Sv) is the SI derived 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 (quality factor) and N (the product of any other multiplying factors), 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. Also known as the relative biological efficiency, Q depends on the nature of the radiation and has a value of one for x rays, gamma rays, and beta particles; 10 for neutrons; and 20 for alpha particles. N is a factor that takes into account the distribution of energy throughout the dose. One Sv is equal to 100 rem. ( NCI )]
