Gray
Defined as the absorption of one joule of radiation energy per kilogram of matter.
History: Named after Louis Harold Gray, a pioneer in the field of radiobiology. Adopted by the CGPM in 1975.
Current use: The primary international unit used in radiotherapy, radiation protection, and radiobiology.
Also written as Gy, grays.
Microgray
One microgray is equal to one millionth of a gray (1.0E-6 grays).
History: Standard SI prefix applied to the gray.
Current use: Used for measuring very low levels of absorbed radiation and environmental doses.
Also written as µGy, uGy, micrograys.
