Dowdall, J. K. Behring, Yu. Bondar, K. Guðnason, C. Israelson, G. Jónsson, S. E. Karlsson, P. K-J. Kock, B. Moller, P. M. Møller, J. Nilssen, J. M. C. Nilsson, V. Zabrotski, | | Abstract: | Car borne measurement systems are and are likely to remain a mainstay in the emergency response arsenal of many countries to incidents involving widespread radioactive contamination as evidenced recently by the events in Fukushima. Such systems constitute a useful means of support provision in situations where another country may be handling a contamination incident. As for any analytical technique, competence must be maintained via exercising of personnel and testing of equipment. For car borne measurement this is intrinsically more difficult than for other activities in emergency response as reproducing the conditions in which such measurements are often required to be made in actuality is impracticable. The MOBELRAD activity, aimed at the provision of an exercise opportunity in making mobile measurements under complex conditions, involved the conducting of such measurements by a number or teams from the Nordic countries within the territory of the Belarusian Exclusion Zone. The exercise involved the making of measurements along a comprehensively precharacterised route through the zone, extending from the borders of the zone to within 10 km of the Chernobyl power plant. The route covered various types of road surface, differing levels of contamination, different terrain types and the teams utilised equipment ranging from small sized LaBr detectors to large volume NaI. The experiences of the teams highlighted the difficulties of making such measurements in landscapes where redistribution processes have had an effect on the distribution of contaminant nuclides and the importance of ensuring appropriate detector-geometry configurations. The exercise demonstrated the suitability of the countries chosen equipment suites in provision of measurement capabilities in third party countries in the event of a serious contamination event and the robustness of such equipment under field conditions. | | Keywords: | Mobile gamma spectrometry, Chernobyl, Exclusion Zone | | Publication date: | 03 Dec 2014 | | ISBN: | ISBN 978-87-7893-400-0 | | Number of downloads: | 2438 | | Download: |  NKS-320.pdf |
