The SI unit for exposure to ionizing radiation in air is coulomb per kilogram (C/kg)1 and curiously - unlike other SI radiation units, a specific name has not been adopted for this unit. This unit officially replaced the old unit - the roentgen - in 1975, with an official transition period lasting at least ten years 2.
