About these units
Rad (rad)
- Definition
- The rad (radiation absorbed dose) is a non-SI unit of absorbed dose equal to 0.01 gray or 100 ergs per gram.
- History
- Introduced in 1953 by the International Commission on Radiation Units and Measurements; largely superseded by the gray since 1985.
- Current use
- Still encountered in US medical and nuclear-industry documentation alongside cGy; 100 rad = 1 Gy.
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.
