Application of particle analysis for verifying nuclear activities

The environmental sample analysis for the IAEA's strengthened safeguards system was identified to be one of the powerful techniques for verification of declared nuclear activities or monitoring the clandestine nuclear activities. The effectiveness and the efficiency of the technique have been tested and proved through the field trials. Among environmental sample analysis techniques, the isotopic ratio measurement of a nuclear material particle in swipe sample has been attracting many attentions due to its powerful effectiveness for verifying nuclear activities which have been done in the facility. Baseline campaigns for various types of nuclear facilities, especially enrichment plant and reprocessing/or hot-cell facilities, were proceeded by the IAEA from early 1996. In this paper, the technical characteristics of the environmental sample analysis are introduced, and the analytical results of the Korean swipe samples at the ITU are reported
