- Gray_(unit) abstract "The gray (symbol: Gy) is a derived unit of ionizing radiation dose in the International System of Units (SI). It is a measure of the absorbed dose and is defined as the absorption of one joule of radiation energy by one kilogram of matter.It is a physical quantity, and does not take into account any biological context, and unlike the pre-1971 non-SI roentgen unit of dose, the gray is defined independently for any target material. The gray is also used to measure specific energy (imparted), and kerma. When measuring kerma, the reference target material must be defined explicitly, usually dry air at standard temperature and pressure.The gray was named after the British physicist Louis Harold Gray, a pioneer in the field of measurement of radium radiation and X-rays and their effects on living tissue, and was adopted as part of SI by the 15th CGPM in 1975. The SI unit is similar to the traditional cgs unit, the rad (equivalent to 0.01 Gy), which remains common in industry in the United States, while "strongly discouraged" in the style guide for U.S. National Institute of Standards and Technology authors.".
