摘要

In AOCRP-1, we introduced the structure of the Glass Badge, the detectable energy range of 10keV~10MeV forphotons and 300keV~3MeV for beta rays, the dose estimation algorism and automatic measurement system (FGD-650). Inaddition, we introduced devices in design for dosimeter and measurement system to link personal information and doseinformation in response to a lot of dosimeter treated. We also reported the characteristics of energy dependence and directiondependence, and detectable dose limit based on 95% confidence interval. Since GUM (Guide to the expression of uncertaintyin measurement) has recently been published by ISO (International Organization for Standardization), technical words andthe way to express the reliability of measurements have been unified, and the performance evaluation of personal dosimeterwill being done with uncertainty. Here in this study, we obtained new additional data of dose linearity, characteristics ofenergy dependence and directional dependence to estimate the uncertainty for the Glass Badge Dosimeter System. We thenevaluated the Type A and B uncertainties separately from these data and combined them to estimate the expanded uncertainty(k=2). We finally concluded that the expanded uncertainty (k=2) satisfied the precision limit of 0.21(k=1.96) which IAEArecommended.
