3D Radioactive Scanning System (3D-RSS)

辐射探测是国土安全和核退役等具有重要社会意义的应用的重要组成部分。在不同类别的电离辐射中，伽马辐射通常是最重要的，因为它是最具穿透力的。在安全和退役应用中，伽马射线探测的要求包括三个步骤：量化测量点的辐射剂量，确定辐射的来源，即哪个同位素(S)负责，以及在周围空间定位源。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型，或者不适合，因为剂量太高，人类操作员无法在该空间工作。在这个项目中，由约克大学核物理小组开发的平面伽马射线探测器将被整合到一个模块化系统中，这是约克大学电子工程系参与INFUSE项目而产生的，目的是为空间应用开发模块化机器人。一旦这些系统整合在一起，就会有一个强大的系统来定位实地的放射源。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。这些探测器可以用来定位房间内放射源(S)的位置。在第二个演示中，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来定位放射源。示威活动将被录像，并将编制一系列宣传材料。这些将被STFC资助的知识交流和商业化使用，以与相关的行业合作伙伴接触，并通过在相关的交易会上做广告来吸引人们对进一步开发项目成果的兴趣。

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.
