3D Radioactive Scanning System (3D-RSS)

辐射探测是国土安全和核退役等社会重要应用的关键组成部分。在不同种类的电离辐射中，伽马辐射通常是最重要的，因为它的穿透力最强。在安全和退役应用中对伽马射线探测的要求遵循三个步骤：在测量点量化辐射剂量，确定辐射源，即哪种同位素负责，并在周围空间定位辐射源。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型，或者因为剂量太高而不适合人类操作员在该空间工作。在这个项目中，由约克大学核物理小组开发的平面伽玛射线探测器将被集成到一个模块化系统中，该系统是由约克大学电子工程系参与的InFuse项目产生的，该项目旨在开发用于空间应用的模块化机器人。一旦这些系统整合起来，就会有一个强大的系统在现场定位放射源。该项目将提供两种演示：一种是三个平面探测器头在房间周围的三脚架上旋转。这些探测器可用于确定房间内放射源的位置。在第二次演示中，平面探测器模块将集成到一个机器人中，该机器人可以在空间内移动以定位放射源。示范活动将录成录像，并将编制一系列宣传材料。由stfc资助的知识交流和商业化项目将利用这些资金与相关的工业伙伴接触，并通过在相关的贸易博览会上做广告，吸引人们对进一步发展项目成果的兴趣。

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.
