| 目的 介绍双热释光元件个人剂量计Hp（10）测量不确定度评定方法。方法 采用GUM法建立测量模型，根据个人剂量计的性能，对个人剂量当量Hp（10）测量不确定度进行评定。结果 当测量结果经非线性响应及能量响应等修正时，Hp（10）的相对扩展不确定度Urel为28%；当测量结果未进行非线性响应及能量响应等修正时，Hp（10）的相对扩展不确定度Urel为33%。结论 该方法可对常规监测中的个人剂量当量Hp（10）测量不确定度进行有效评定。 |

| Objective To describe the evaluation method of uncertainty in measurement of depth individual dose equivalent. Methods Based on the performance of the personal dosimeter, GUM method was used to evaluate the uncertainty of Hp(10) measurement by using a personal dosimeter. Results The relative extended uncertainty was 28% when the measurement result was corrected by nonlinear response and energy response, as well as 33% when not corrected in the same way. Conclusions This method can be used to effectively evaluate the uncertainty arising from personal dose equivalent Hp(10) measurement in routine monitoring. |
