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 gray (symbol: Gy) is a derived unit of ionizing radiation dose in the International System of Units (SI). It is defined as the absorption of one joule of radiation energy per one kilogram of matter.he gray was named after British physicist Louis Harold Gray, a pioneer in the field of X-ray and radium radiation measurement, and their effects on living tissue. It was adopted as part of the International System of Units in 1975.
