摘要
本文报道的剂量计是使用两种重铬酸银浓度和应用两个测量波长。每一种重铬酸银浓度下,吸收剂量和辐照前后吸光度差之间是一个二次多项式关系,多项式常数同辐照前重铬酸银浓度关系不密切.同时测定了温度系数和过氯酸的酸度等对辐照前后吸光度差的影响。最后得出了此剂量计可适用的剂量范围为0.7—50kGy。
In this paper the radiometric properties of a silver dichromate dosimeter of grinding mouth glass bottle in the dose range of 0. 7 - 50 kGy are reported. Relation between absorbed dose (kGy) and net absorbance ΔA( = Ao-Ai) is a second-order polynominal, polynominal constant does not depend on Ao. Temperature coefficient during measurement and irradiation, acidity affect of perchloric acid as well as dose rate effects in 22. 3 - 5400Gy/ h range and so on have been experimentally investigated. The applied range and total uncertainty of the dosimeter are discussed.
