Gray (unit) – (symbol: Gy), is the SI unit of energy for the absorbed dose of radiation. One gray is the absorption of one joule of radiation energy by one kilogram of matter. One gray equals 100 rad, an older unit. Heat; Mass–energy equivalence – where mass has an energy equivalence, and energy has a mass equivalence; Megawatt; Net ...
