The gray (symbol: Gy) is the SI unit of absorbed dose of ionizing radiation. It quantifies the amount of radiation energy absorbed per unit mass of tissue. Specifically, one gray is defined as the absorption of one joule of radiation energy by one kilogram of matter. The gray is commonly used in the context of radiation therapy, radiology, and nuclear medicine to assess the amount of radiation exposure that tissues receive.
