This paper presents the measurement of the dose equivalent Hp(10) to low (0.005-1) mSv and high (20-1000) mSv doses by exposure at (241)Am and (173)Cs radiation sources of the halide film with FB-III-D dosimeter system. Accuracy of measurements, standard error of the dose mean value (SEM) and some comments about ability to reread of dosimetric films were determined. A good accuracy was obtained over the important dose ranges. In the low dose range, under 0.1 mSv, the SEM values of the (241)Am doses, recorded on the film under plastic filter, are between -21.36% and +47.51%. For 0.1-500 mSv (137)Cs dose range the SEM values are from -9.55% to +7.24%.
本文介绍了使用FB-III-D剂量计系统,通过在(241)Am和(173)Cs辐射源下照射卤化银胶片,来测量低剂量(0.005 - 1)mSv和高剂量(20 - 1000)mSv的剂量当量Hp(10)。确定了测量精度、剂量平均值的标准误差(SEM)以及关于剂量测定胶片再读取能力的一些评论。在重要的剂量范围内获得了良好的精度。在低剂量范围,即低于0.1 mSv时,塑料滤片下胶片上记录的(241)Am剂量的SEM值在-21.36%至+47.51%之间。对于0.1 - 500 mSv的(137)Cs剂量范围,SEM值为-9.55%至+7.24%。
