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 Picocoulombs per kilogram
The picocoulomb per kilogram (pC/kg) equals 10⁻¹² C/kg. Environmental gamma exposure rates in very low background areas approach pC/kg/h; precision ionisation chamber calibration laboratories measure leakage and secondary ionisation currents in terms of pC/kg. 1 pC/kg = 10⁻¹² C/kg = 10⁻³ nC/kg.
