About Nanocoulombs per kilogram
The nanocoulomb per kilogram (nC/kg) equals 10⁻⁹ C/kg. Used in modern SI-based environmental radiation monitoring; equivalent to ~3.88 µR. National metrology institutes calibrate secondary standard ionisation chambers with responses expressed in nC/kg. 1 nC/kg = 10⁻⁹ C/kg = 10⁻³ µC/kg.
About Milliroentgens
The milliroentgen (mR) equals 2.58 × 10⁻⁷ C/kg. Standard unit in US health physics for area gamma surveys: personal dosimeters and Geiger counters in medical and industrial radiography settings display mR/h; NRC licence conditions often specify dose-rate limits in mR/h at facility boundaries. 1 mR = 2.58 × 10⁻⁷ C/kg.
