Frequently asked questions
Absorbed dose is the radiation energy deposited per unit mass. It describes a physical quantity rather than a biological weighting.
A gray is one joule of absorbed radiation energy per kilogram of material. It is the SI unit for absorbed dose.
Gray measures absorbed energy, while sievert adjusts dose to reflect biological effect. The numbers are not automatically equal in all situations.
The rad is an older absorbed-dose unit. One gray equals 100 rad.
