About These Units
Millirad (mrad)
A millirad (mrad) equals 0.001 rad or 10 μGy. Used in medical dosimetry: dental bitewing 0.5-2 mrad, chest X-ray 10-20 mrad. Provides convenient scale for diagnostic imaging dose specifications.
Milliroentgen (mR)
A milliroentgen (mR) equals 0.001 roentgen. Radiation survey meters often display mR/h for monitoring X-ray and gamma fields. Natural background: 10-20 mR/year. Typical survey meter range: 0-1000 mR/h.
