Radiation detection provides a crucial component of societally-important applications such as homeland security and nuclear decommissioning. Of the different classes of ionising radiation, gamma radiation is usually the most important as it is the most penetrating. The demands of gamma ray detection in security and decommissioning applications follow three steps: quantify the dose of radiation at the point of measurement, identify the origin of the radiation i.e. which isotope(s) are responsible and locate the source in the surrounding space. The latter is usually the most challenging, especially as it may be highly time consuming and labour intensive, or is unsuitable because the dose is too high for a human operator to be able to work in that space.In this project, planar gamma-ray detectors developed by the nuclear physics group at the University of York will be integrated into a modular system arising from the involvement of the Department of Electronic Engineering at York in the InFuse project to develop modular robotics for space applications. Once these systems are integrated, a powerful system will exist for locating radioactive sources in the field. The project will provide two demonstrations: one with three planar detector heads rotating on tripods positioned around a room. These detectors can be used to localise the position of a radioactive source(s) within the room. In a second demonstration, the planar detector modules will be integrated into a robot which can move around a space to locate radioactive sources. The demonstrations will be videoed and a range of publicity materials will be developed. These will be used by an STFC-funded Knowledge Exchange and Commercialisation to engage with relevant industrial partners and to attract interest to further development of the project outcomes by advertising at relevant trade fairs.

辐射探测是国土安全和核退役等重要社会应用的重要组成部分。在不同种类的电离辐射中，伽马辐射通常是最重要的，因为它是最具穿透力的。安全和退役应用中的伽马射线探测要求遵循三个步骤：量化测量点的辐射剂量，确定辐射的来源，即哪些同位素负责，并在周围空间中定位辐射源。后者通常是最具挑战性的，特别是因为它可能非常耗时和劳动密集，或者因为剂量太高而不适合人类操作员在该空间中工作。平面γ-由约克大学的核物理小组研制的射线探测器将被集成到一个模块化系统中，该系统是由电子工程系参与研制的，约克参与了为太空应用开发模块化机器人技术的Incubator项目。一旦这些系统被整合，将存在一个强大的系统，用于定位现场的放射源。该项目将提供两个演示：一个是三个平面探测器头在房间周围的三脚架上旋转。这些探测器可用于定位房间内放射源的位置。在第二次演示中，平面探测器模块将被集成到一个机器人中，该机器人可以在空间中移动以定位放射源。将对示范活动进行录像，并制作一系列宣传材料。这些将由STFC资助的知识交流和商业化项目用于与相关行业合作伙伴合作，并通过在相关交易会上做广告来吸引对进一步开发项目成果的兴趣。
