摘要
用硫酸亚铁剂量计和辐射变色薄膜剂量计相结合的化学方法，测定了水和聚乙烯材料中电子的吸收剂量、深度剂量分布和实际射程。测量结果和外推电离室的测量结果进行了比较，水和聚乙烯中电子最大吸收剂量的测量值在２％范围内一致。本方法测量水的吸收剂量总不确定度为２．１％，测量聚乙烯和其它物质的吸收剂量总不确定度为６．５％，置信概率为９５％。
The ferrous sulphate dosimeter combined with the radiochromic film dosimeter,the electron absorbed dose is measured as well as its depth dose distribution and the actual range in water and polythylene. The maximum absorbed doses measrued in water and polythylene are compared with those obtained with extrapolation ionization chamber,and the results of the two methods are agreed within 2%.The total uncertainty of absorbed dose in water,polythylene and other materials are 2 1% and 6 5%,respectively.The confident level is not less than 95%.
