NKS Programme Area: | NKS-B | Research Area: | Emergency preparedness | Report Number: | NKS-271 | Report Title: | Gamma Spectrometric Discrimination of Special Nuclear Materials | Activity Acronym: | GASMAT | Authors: | M. Dowdall, A. Mattila, H. Ramebäck, H.K. Aage, S.E. Pálsson, | Abstract: | This report presents details pertaining to an exercise conducted as part of the NKS-B programme using synthetic gamma ray spectra to simulate the type of data that may be encountered in the interception of material potentially containing special nuclear materials. A range of scenarios were developed involving sources that may or may not contain special nuclear materials. Gamma spectral data was provided to participants as well as ancillary data and participants were asked, under time constraint, to determine whether or not the data was indicative of circumstances involving special nuclear materials. The situations varied such that different approaches were required in order to obtain the correct result in each context. In the majority of cases participants were able to correctly ascertain whether or not the situations involved special nuclear material. Although fulfilling the primary goal of the exercise, some participants were not in a position to correctly identify with certainty the material involved, Situations in which the smuggled material was being masked by another source proved to be the most challenging for participants. | Keywords: | Nuclear smuggling, gamma spectrometry, special nuclear material, identification | Publication date: | 20 Dec 2012 | ISBN: | ISBN 978-87-7893-344-7 | Number of downloads: | 3931 | Download: | NKS-271.pdf |
