Assessment of dose rates with environmental dosimeters typically takes much longer than with personal dosimeters. This work compares the results of two dosimetry systems with the aim of showing how to use personal dosimeters as environmental dosimeters in the case of radiological and nuclear emergencies, when the processing of a large number of dosimeters is essential. For this purpose, a long-term study has been carried out on the variability of the response of personal (CaSO:Tm) and environmental (LiF:Mg,Cu,P) dosimeters corrected for the influence of secondary cosmic radiation (SCR). Comparison with each other provided a correlation factor between measurements made using these two passive dosimetry systems. The SCR response of the personal dosimeter was found to be 0.41 (σ = 0.03) significantly lower than 1.24 (U = 0.12) that of the environmental dosimeter, which notably affects the comparison of dose measurements made with these two systems in free field. The correlation factor found of 0.86 (σ = 0.08) between the personal and environmental dosimeters allows preparing the personal dosimeters to be used in environmental radiation monitoring.

真实场景中使用环境剂量计和个人剂量计处理放射和核紧急情况的剂量测量比较


使用环境剂量计评估剂量率通常比个人剂量计花费更长的时间。这项工作比较了两种剂量测定系统的结果，目的是展示在放射和核紧急情况下，当大量剂量计的处理至关重要时，如何使用个人剂量计作为环境剂量计。为此，我们对个人 (CaSO:Tm) 和环境 (LiF:Mg,Cu,P) 剂量计响应的变异性进行了长期研究，并针对二次宇宙辐射 (SCR) 的影响进行了校正。相互比较提供了使用这两个被动剂量测定系统进行的测量之间的相关系数。个人剂量计的 SCR 响应被发现为 0.41 (σ = 0.03)，明显低于环境剂量计的 1.24 (U = 0.12)，这显着影响了这两个系统在自由场中进行的剂量测量的比较。个人剂量计和环境剂量计之间的相关系数为 0.86 (σ = 0.08)，允许准备用于环境辐射监测的个人剂量计。
