Abstract

This paper investigates and compares two widely employed techniques for measuring natural gamma absorbed dose rate in outdoor air: the thermoluminescent dosimeter (TLD) and the Geiger-Mueller (GM) detector-based environmental radiation monitor (ERM). Over two decades (2003–2023), measurements were conducted at eighteen investigation sites having a wide variation of local dose rate values. The TLDs accumulated quarterly doses, while the ERMs recorded hourly dose rates. The comparison of mean dose rates obtained by the two methods agreed within ± 30% for all sites. A strong positive correlation was obtained between the two methods.

TLD和GM探测器长期测量室外空气中自然伽马吸收剂量率的比较研究

本文研究并比较了两种广泛使用的测量室外空气中自然伽马吸收剂量率的技术：热释光剂量计（TLD）和基于盖格-穆勒（GM）探测器的环境辐射监测仪（ERM）。在二十年（2003-2023年）期间，在当地剂量率值变化很大的18个调查点进行了测量。顶级区域按季度累积剂量，而辐射管理单位则按小时记录剂量率。两种方法得到的平均剂量率比较在±30%范围内一致。两种方法之间有很强的正相关。
