The possibility of using the specific responses of the high temperature Peaks 6 and 7 and Peaks 4 and 5 to different LET radiations was mentioned in the past mainly for very high doses. The applicability of the two regions method for thermal neutrons--gamma ray mixed field dosimetry was investigated by analysing the response of LiF:Mg,Ti dosemeters irradiated to different ratios of thermal neutrons and gamma rays at radiation protection dose levels encountered in routine work conditions, up to approximately 50 mSv. The Region of Interest method was used to define the areas of the Peaks 4 + 5 and 6 + 7. We found that a simple algorithm can be used to determine with good accuracy the separate contributions of neutron and gamma doses.
过去主要针对非常高的剂量提及了利用高温峰6和峰7以及峰4和峰5对不同传能线密度辐射的特定响应的可能性。通过分析在常规工作条件下遇到的辐射防护剂量水平（高达约50毫希沃特）下，LiF:Mg,Ti剂量计对不同热中子与γ射线比例照射的响应，研究了双区域方法在热中子 - γ射线混合场剂量测定中的适用性。采用感兴趣区域方法来定义峰4 + 5和峰6 + 7的区域。我们发现可以使用一种简单算法来准确确定中子剂量和γ剂量的单独贡献。
