Application of whole-body personal TL dosemeters based on a high-sensitivity LiF:Mg,Cu,P (MCP-N) in mixed field beta-gamma radiation has been characterised. The measurements were carried out with (90)Sr/(90)Y, (85)Kr and (137)Cs point sources to calculate the energy response and linearity of the TLD response in a dose range of 0.1-30 mSv. From the result, calibration curves were obtained, enabling the readout of individual dose equivalent Hp(10) from gamma radiation and Hp(0.07) from beta radiation in mixed field beta-gamma. Limitation of the methodology and its application are presented and discussed.
基于高灵敏度氟化锂镁铜磷（MCP-N）的全身个人热释光剂量计在混合场β-γ辐射中的应用已得到表征。使用锶-90/钇-90、氪-85和铯-137点源进行测量，以计算在0.1 - 30 mSv剂量范围内热释光剂量计响应的能量响应和线性度。根据结果获得了校准曲线，能够读出混合场β-γ中γ辐射的个人剂量当量Hp(10)和β辐射的Hp(0.07)。介绍并讨论了该方法及其应用的局限性。
