Radiation exposure definition

Radiation exposure means the quotient of dQ by dm where "dQ" is the absolute value of the total charge of the ions of one sign produced in air when all the electrons (negatrons and positrons) liberated by photons in a volume element of air having mass "dm" are completely stopped in air. The SI unit of radiation exposure is the coulomb per kilogram (C/kg). (See section 33.1-10-01-14 units of exposure, dose, and activity for the special unit equivalent "roentgen" (R).)
