About these units
Centigray (cGy)
- Definition
- A centigray (cGy) is one hundredth of a gray, numerically equal to one rad.
- History
- It was introduced to provide continuity with the older rad unit.
- Current use
- Radiation oncologists commonly prescribe doses in cGy because it matches the familiar rad scale.
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.
