In order to detect undeclared activities of nuclear facilities, Japan Atomic Energy Research Institute (JAERI) has developed analytical methods for safeguards environmental samples. As for particle analysis of safeguards environmental sample analysis which can determine isotope ratios of nuclear materials for individual particles, secondary ion mass spectrometry (SIMS) is known as a powerful method. However, it is difficult to analyze particles having diameter below 1μm due to its detection limit. To overcome the problem, JAERI is developing an analytical method using fission track (FT) technique. The outline of the method is described in this report.
