Abstract
The doses of gamma-rays and electron beams were evaluated by Fricke do simetry and the responses of cellulose triacetate dosimeter (CTA) and radiochromic film dosimeter (RCF) to the two types of radiations were compared to investigate their dose rate dependence. Both the change in absorbance at 280 nm of CTA and that in absorbance at 510 nm of RCF c aused by gamma-irradiation were larger than those by electron-irradiat ion, when the dosimeters were irradiated to the same dose. The results in this study suggest that the responses of CTA and RCF are dependent upon dose rate.
