WebA quantity used to indicate the amount of ionization in air produced by x- or gamma-ray radiation. The unit is the roentgen (R). For practical purposes, one roentgen is comparable to 1 rad or 1 rem for X ray and gamma radiation. The SI unit of exposure is the coulomb per kilogram (C/kg). One R = 2.58 x 10-4 C/kg. Gamma rays, or gamma radiation Web31 Mar 2024 · The Roentgen (R) is a measure of air ionization (“exposure”): This measurement is easily accomplished using a GM tube (an ion chamber operated at a voltage putting its operation in the Geiger region) and survey meter as long as the energy field being measured is uniform.
