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 absorbed dose, depth dose distribution and actual range of electrons in water and polyethylene were measured by a chemical method combined with a ferrous sulfate dosimeter and a radiochromic film dosimeter. The results of the measurements were compared with those of the extrapolated ionization chamber. The measurement of the maximum absorbed dose of electrons in water and polyethylene was within 2%. The total uncertainty of the absorbed dose measured by this method is 2.1%. The total uncertainty of the absorbed dose of polyethylene and other materials measured is 6.5%, and the confidence probability is 95%.
