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.
Microroentgen (μR)
A microroentgen (μR) equals 0.001 mR. Used in environmental radiation monitoring, radon measurements, and low-level contamination surveys. Natural background: 10-20 μR/h typical. Sensitive ion chambers measure in μR/h.
