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.
Nanogray (nGy)
A nanogray (nGy) equals 10⁻⁹ grays. Used in background radiation measurements and environmental monitoring. Natural background dose rate: 50-200 nGy/h from cosmic rays and terrestrial sources. Sensitive dosimeters measure in nGy.
