Assessment of uncertainty in Hp(10) measurement by using a double TLD element personal dosimeter / 中华放射医学与防护杂志

ABSTRACT

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.
