This paper presents the results of the evaluation of the uncertainty in measurement of the personal dose equivalent, Hp(10), at nine individual monitoring services (IMSs) in Asia and the Pacific region. Different types of passive dosemeters were type-tested according to the International Electrotechnical Commission 62387 requirements. The uncertainty in measurement was calculated using the Guide to the Expression of Uncertainty in Measurement approach. Expanded uncertainties ranged between 24 and 86% (average = 38%) for Hp(10) values around 1 mSv and between 14 and 40% (average = 27%) for doses around the annual dose limit, Hp(10) = 20 mSv. The expanded uncertainties were lower than the 1.5 factor in either direction proposed by the International Commission on Radiological Protection for doses near the relevant dose limits. This indicates an acceptable level of uncertainty for all participating IMSs. Uncertainty evaluation will help the IMSs to acknowledge the accuracy of their measurements.
本论文介绍了对亚洲及太平洋地区九个个人监测服务机构(IMS)的个人剂量当量Hp(10)测量不确定度评估的结果。根据国际电工委员会 62387 要求,对不同类型的被动剂量计进行了型式检验。使用《测量不确定度表示指南》方法计算了测量不确定度。在 Hp(10)值约为 1 mSv 的情况下,扩展不确定度范围在 24%至 86%(平均值为 38%)之间,在剂量接近年剂量限值 Hp(10)=20 mSv 的情况下,扩展不确定度范围在 14%至 40%(平均值为 27%)之间。扩展不确定度低于国际辐射防护委员会建议的在相关剂量限值附近剂量的 1.5 倍因子。这表明所有参与的 IMS 的不确定度处于可接受水平。不确定性评估将有助于 IMS 承认其测量的准确性。
