Basic Quantities and Units in Radiation Safety,To characterize and measure ionizing radiation, we need quantities that describe the source, the radiation field at the point of interest, and the energy deposited in the material with which ionizing radiation interacts. The values assigned to the various quantities may be obtained by calculations and/or measurements.
