About These Units
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.
Millirem (mrem)
A millirem (mrem) equals 0.001 rem or 10 μSv. US dosimetry standard: natural background 300-400 mrem/year, occupational limit 5,000 mrem/year, public limit 100 mrem/year above background. Chest X-ray: ~2 mrem.
