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.
Absorbed dose is a measure of the energy deposited in a medium by ionizing radiation.It is equal to the energy deposited per unit mass of medium, and so has the unit J/kg or gray (Gy) where 1Gy = 1Jkg -1. The absorbed dose is not a good indicator of the likely biological effect.1 Gy of alpha radiation would be much more biologically damaging than 1 Gy of photon radiation for example.Appropriate weighting factors can be applied reflecting the different relative biological effects to find the equivalent dose.bsorbed dose is a measure of the energy deposited in a medium by ionizing radiation.
