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 WebExamples of commonly used PPE for radiation protection from X-rays and gamma rays include: Lead aprons or vests. Wearing lead aprons can reduce a worker's radiation dose. Customized lead (or lead equivalent) aprons are available for a wide range of occupational settings and job tasks.
