Abstract
Minimax dental X-ray film extra fast, duPont Dosimeter type 552 single film packet, and an extrapolation type ionization chamber were exposed under identical conditions to 0.5 to 1.4 Mev electrons and to the beta rays from uranium. A 7 mg./cm2 polystyrene plate was used on the ionization chamber to simulate the dead layer of the skin. Film response was linearly proportional to dosage and independent of electron energy. Density dosage plots for U238 beta rays gave a slope 1/2 of that detd. for the electrons. Dependence of density on paper film wrapper was demonstrated and a step-wedge filter was suggested permitting extrapolation of densities to zero filter thickness.This publication has 1 reference indexed in Scilit:
