Abstract
Monte Carlo calculations were applied to determine the radiation dose absorbed in water phantoms. Monoenergetic incident X-ray beams with energies from 15-100 keV and phantom thicknesses from 5-20 cm were considered. The spatial distributions of energy absorption in the phantom, the rad/R conversion factors, the average rad/R conversion factors and the scatter-to-primary ratios of absorbed dose were calculated. The relative absorbed doses were compared under various imaging conditions when the transmitted radiation produced a given optical density on radiographic film. The information provided will be useful for the estimation of radiation doses in various radiographic procedures.
