熱蛍光線量計による個人被曝管理 (I)

熱蛍光線量計の諸特性

抄録

In order to use a thermoluminescence dosimeter for personal monitoring, some practical characteristics such as reproducibility, deviation among elements, degradation of sensitivity were examined during the repeated usage over one year. It was shown that the correction of the reading to compensate for the deviation in sensitivities by the factor determined for each element is necessary. The elements mostly showed the degradation of sensitivity during the usage. The degradation was supposed to be caused essentially by the repeated annealing. The values by thermoluminescence dosimeter agreed fairly well with those by film badge in the wide range of energies higher than several 10 keV.
