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.
Rep
A legacy unit defined as the dose of any ionizing radiation that results in the absorption of 93 ergs per gram of tissue.
History: Introduced in the 1940s to extend the roentgen to radiations other than X-rays/gamma rays.
Current use: Obsolete, replaced by the rad and subsequently the gray.
Also written as rep.
