Abstract

Development of technologies for the rapid, in-situ characterisation of contaminated facilities (where man-entry is not possible) is a key requirement to speed up nuclear decommissioning. Similarly prevention of nuclear terrorism is dependent upon the accuracy and strength of the radiation monitoring systems. Organic liquid scintillator detectors are becoming popular in radiation detection applications including nuclear decommissioning, nuclear safety and security as a result of recent advances in digital pulse-shape discrimination methods. They generally sensitive to both neutrons and gamma rays, where pulse shape discrimination can be used to discriminate between neutrons and gamma rays. In this work, experimentally collected events are discriminated between neutrons and gamma-rays using pulse shape discrimination, and images produce for each measurement in terms of the angular distribution (i.e. intensity of the radiation type) of events for total counts, gamma rays and neutrons. Based on these images, it can be easily identified the actual location of the source.
