Noun. 1. Gy-the SI unit of energy absorbed from ionizing radiation; equal to the absorption of one joule of radiation energy by one kilogram of matter; one gray equals 100 rad. gray. radioactivity unit-a measure of radioactivity.
The rad is the traditional unit of dose. 1 rad = 100 ergs per gram or 0.01 Joules per kilo-gram. The gray (Gy) is the SI unit of absorbed dose, and is the amount of radiation required to deposit 1 joule of energy in 1 kilogram of matter. 1 gray = 100 rads. 1 rad = 10 milli-grays.
