This work details an innovative method to search a complex enclosed area for a gamma-ray emitting material using a handheld gross-counts gamma detector. It is not a wide area search tool. It relies on triangulating a search area and using the Currie limit of detection to determine the presence of radioactive gamma-ray emitting materials. Results of experimental trials of the model indicate its effectiveness in detecting radiation sources in complex environments. This highlights its potential application in locating radiological material for nuclear security purposes. The method is currently 2-D but is being extended to 3-D.

一种新型搜索方法在手持式伽马辐射探测器中的应用

这项工作详细介绍了一种使用手持式总计数伽马探测器在复杂的封闭区域中搜索伽马射线发射材料的创新方法。它不是一个广域搜索工具。它依赖于对搜索区域进行三角测量并使用 Currie 检测极限来确定放射性伽马射线发射材料的存在。该模型的实验试验结果表明其在检测复杂环境中的辐射源方面的有效性。这突出了其在定位用于核安保目的的放射性材料方面的潜在应用。该方法目前是 2-D，但正在扩展到 3-D。
