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 Kiloroentgens
The kiloroentgen (kR) equals 0.258 C/kg. Used in radiation hardness testing of electronics and legacy nuclear weapons effects literature; total ionising exposure inside nuclear facilities during design-basis accident scenarios is cited in kR; some older radiation therapy machine output specifications use kR/min. 1 kR = 0.258 C/kg = 10³ R.
