sievert (Sievert)

SI dose equivalent measure. Symbol: Sv. It is a unit of biologic dose of ionizing radiation. The Sievert makes it possible to normalize doses of different types of radiation. It takes into account the relative biologic effectiveness of ionizing radiation, since each form of such radiation--e.g., X rays, gamma rays, neutrons-- has a slightly different effect on living tissue for a given absorbed dose. The dose equivalent of a given type of radiation (in Sievert) is the dose of the radiation in Gray multiplied by a quality factor that is based on the relative biologic effectiveness of the radiation. Accordingly, one Sievert is generally defined as the amount of radiation roughly equivalent in biologic effectiveness to one Gray of gamma radiation. Sievert = J/kg = m^2*s^(-2)
