gray

A unit of absorbed dose of radiation equal to an energy absorption of 1 Joule per kilogram of irradiated material. 1 Gy is equivalent to 100 RADS. In radiotherapy, radiation is commonly applied to the area of the tumour in a dosage of around 2 Gy a day, five days a week for periods of 3–6 weeks.
