Absorbed dose (D): The quotient of dE by dm, where dE is the mean energy imparted by ionizing radiation to matter of mass dm. The unit for absorbed dose is the joule per kilogram (J kg–1), with the special name gray (Gy).
Accelerator: In this Report, refers to an electron accelerator, which is a device for imparting kinetic energy to elec- trons, with the kinetic energy being >2 and <50 data-blogger-escaped-br=”” data-blogger-escaped-mev.=””>
