10 th European Commission Conference on EURATOM Research and Training in Safety of Reactor Systems

Abstract

Introduction To reduce the dose uptake of workers in a nuclear environment, robots or gamma cameras are often used to localise hotspots and sources. A semi-autonomous robotic platform was developed during a previous research project called ARCHER. This robot limits the need for human intervention. But still uses the time-consuming way of measuring point by point. Gamma cameras can measure from relatively far away and therefore reduce the chance of contamination. This study combined a single layer Compton Camera with a 3D camera to better visualise the source and estimate the source-to-detector distance. Preliminary tests were performed with a 137 Cs source.
