The gray (symbol: Gy) is a derived unit of ionizing radiation dose in the International System of Units (SI). It is defined as the absorption of one joule of radiation energy per one kilogram of matter.It is used as a measure of absorbed dose, specific energy (imparted) , and kerma (an acronym for  k inetic e nergy r eleased per unit ma ss).It is a physical quantity, and does not take into account any biological context.he absorbed dose also plays an important role in radiation protection as it is the starting point for calculating the stochastic effect of low levels of radiation. The stochastic health risk for radiation protection dose assessment is defined as the probability of cancer induction and genetic damage.
