The objective of this work was to perform an extensive side-by-side comparison between a radiophotoluminescence (RPL) dosimetry system and thermoluminescent dosimeters (TLDs) or EDIS-1™ Environmental Direct Ion Storage Dosimeters during environmental and area monitoring. The measurement locations include points around and within the perimeter of the Paul Scherrer Institute (PSI) and nearby facilities. These data are complemented by a study on the RPL detection limit, uncertainty and dose linearity, as well as two intercomparisons of environmental dosimeters, a Swiss intercomparison organized by PSI and an international intercomparison organized by the German National Metrology Institute (Physikalisch-Technische Bundesanstalt, PTB, Germany). The laboratory irradiations show that the detection limit of the RPL dosimeters is < 50 μSv if the time between pre-dose measurement and readout is < 200 days, and the response is linear up to at least 100 mSv with less than 15% deviation from linearity, satisfying the requirements of the Swiss dosimetry ordinance. The RPL doses were more consistent than the TLD doses over time. The RPL system shows slightly lower doses (12–14%) in comparison with EDIS-1 dosimeters. The intercomparisons for passive environmental dosimeters in terms of H*(10) showed a good agreement between the RPL dose values and the conventional true values. Altogether, the results demonstrate the equivalence between RPL and the other dosimetry systems, providing support for the RPL adoption for environmental dosimetry.

这项工作的目的是在环境和区域监视期间，在放射光致发光（RPL）剂量测定系统和热发光剂量计（TLD）或EDIS-1™环境直接离子存储剂量计之间进行广泛的并排比较。测量位置包括Paul Scherrer Institute（PSI）及其周围设施周围和内部的点。这些数据得到了RPL检测限，不确定性和剂量线性的研究以及两个环境剂量计的比对，PSI组织的瑞士比对和德国国家计量学会组织的国际比对（Physikalisch-Technische Bundesanstalt，PTB，德国）。实验室辐射表明，如果在剂量前测量和读数之间的时间小于200天，则RPL剂量计的检测极限为<50μSv，并且响应至少在100 mSv时呈线性，线性偏差小于15％ ，符合瑞士剂量法令的要求。随着时间的推移，RPL剂量比TLD剂量更一致。与EDIS-1剂量计相比，RPL系统显示的剂量略低（12–14％）。以H *（10）表示的无源环境剂量计的比对表明RPL剂量值和常规真实值之间有很好的一致性。总之，结果证明了RPL与其他剂量测定系统之间的等效性，为RPL在环境剂量测定中的应用提供了支持。
