About these units
Gray (Gy)
- Definition
- The gray (Gy) is the SI unit of absorbed radiation dose, equal to one joule of energy deposited per kilogram of matter.
- History
- Named after British radiobiologist Louis Harold Gray and adopted by the CGPM in 1975, replacing the older rad.
- Current use
- Grays describe doses in radiation therapy, nuclear accidents, and radiobiology research.
Microgray (µGy)
- Definition
- A microgray (µGy) is one millionth of a gray.
- History
- A metric sub-multiple for very low dose measurements.
- Current use
- Background radiation levels and some occupational dose monitoring use microgray.
