The general effects of backscattering on measured radiation doses are
fairly vell established. Further, knowledge ef depth (tissue)<doss eurves has
edvanced to a quantitative state.® Thus, there secas to be little doubt that
a film bedge or dosizeter worn om the parsca will cver-estinete the gum
radiation dose delivered at a depth ef five centimeters (assumed depth of
blood forming organs). A major factor in determining this difference is ths
quality of radiation wer considerstion.
