Coulomb per kilogram
The amount of radiation that creates one coulomb of charge in one kilogram of dry air.
History: Replaced the roentgen as the standard unit for radiation exposure in the SI system.
Current use: Used in radiation protection and dosimetry to measure the ionizing ability of X-rays and gamma rays in air.
Also written as C/kg.
Parker
Equivalent to the roentgen in most contexts.
History: Named after Herbert Parker, a pioneer in health physics.
Current use: Obsolete, used only in historical radiation safety texts.
Also written as parker.
