Environmental sampling is the important one of IAEA safeguards technology, the aim of which is detecting the undeclared nuclear activities. Analyzing isotopic ratio of single uranium-bearing particle in swipe samples was a effective analytic technique in virtue of its ability of achieving the present or past information of nuclear facilities. For this purpose, a new method of Fission track (FT) technique combined with thermal ionization mass spectrometry (TIMS) was developed.
