About Coulombs per kilogram
The coulomb per kilogram (C/kg) is the SI derived unit of radiation exposure, equal to 1 coulomb of ion charge liberated per kilogram of dry air. It replaced the roentgen in SI. Calibration of clinical X-ray beams with free-air ionisation chambers and parallel-plate chambers yields results in C/kg. 1 C/kg ≈ 3876 R.
About Microroentgens
The microroentgen (µR) equals 2.58 × 10⁻¹⁰ C/kg. Standard unit for very low environmental gamma dose rates in legacy US instrumentation: airborne radiological surveys over background areas report µR/h; EPA environmental monitoring network stations historically logged µR/h for outdoor gamma levels. 1 µR = 2.58 × 10⁻¹⁰ C/kg.
