RADIOMETRIC PROPERTIES OF PR-CN(PVB) RADIOCHROMIC DYE FILM DOSIMETER FOR THE MEASUREMENT OF ELECTRON DOSE

    Graphical Abstract
    • Abstract
  • In the paper the following radiometric properties of PR-CN (PVB)radiochremic dye film dosimeter for the measurement of electron beam absorbeddose are reported; a good linear function that exists between the change in opticaldensity per unit thickness and absorbed dose in the range of 0.3 k--120kGy; asmall energy dependence; the ratio of response for ~(147)Pm and ~(90)Sr plus ~(90)Y toidentical dose which is about 1:2.4; equivalent response for gamma rays from~(60)Co and electrons with the high energy; no dose rate effects over a wide rangeof dose and dose rate; A routine method for calibration is established andexamples for measuring the depth dose distributions for electron beams from two kinds of accelerators are given.
