1 µGy = 0.0001 rad
Example: 1 rad = 10,000 µGy
Rad
Defined as the absorption of 100 ergs of energy per gram of matter, equal to 0.01 gray.
History: Acronym for Radiation Absorbed Dose. Established in 1953 as a replacement for the roentgen.
Current use: Still frequently used in the United States, though officially discouraged in favor of the gray.
Also written as rad, rads.
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.
