The stripping method for ambient dose estimation has been used for detectors such as high-purity Ge (HPGe). This method strips the spectrum from the partial absorptions produced in the detector leaving only the events corresponding to the full absorption of a gamma ray. In the present study, this method is applied to a 1″ × 1″ LaBr3(Ce) detector using the PENELOPE/penEasy Monte Carlo code to obtain both the partial absorptions and detector full peak efficiency. The stripping method has been validated from a set of gamma fluxes carried out at the accredited laboratory of the Institute of Energy Technologies of the Technical University of Catalonia and results were obtained with differences <5 %. After validation, the LaBr3(Ce) monitor was installed on the roof of the institute premises working in parallel with a photon equivalent dose monitor, model FHZ 601A from the FAG Company. The derived H*(10) values from the LaBr3(Ce) detector show good agreement with those derived from the dose monitor.
用于环境剂量估算的剥谱法已应用于高纯锗（HPGe）等探测器。该方法从探测器中产生的部分吸收谱中剥离出仅对应于伽马射线全吸收的事件。在本研究中，使用PENELOPE/penEasy蒙特卡罗代码将该方法应用于1英寸×1英寸的溴化镧铈（LaBr3(Ce)）探测器，以获得部分吸收和探测器全峰效率。通过在加泰罗尼亚理工大学能源技术研究所认可实验室进行的一组伽马通量验证了剥谱法，获得的结果差异<5%。验证后，将溴化镧铈（LaBr3(Ce)）监测器安装在该机构大楼的屋顶上，与FAG公司的FHZ 601A型号光子当量剂量监测器并行工作。溴化镧铈（LaBr3(Ce)）探测器得出的H*(10)值与剂量监测器得出的值显示出良好的一致性。
