About these units
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.
Milligray (mGy)
- Definition
- A milligray (mGy) is one thousandth of a gray.
- History
- A metric sub-multiple of the gray used for lower diagnostic doses.
- Current use
- CT scans typically deliver organ doses of 10–30 mGy; milligray is standard in diagnostic radiology.
