As a rapid and simple analytical method for alpha nuclides in metal waste of which surface was contaminated by radionuclides, extraction chromatography using TRU resin for analysis of Pu and Am and UTEVA resin for analysis of Th and U is evaluated. The metal waste contained lots of Fe. Trivalent iron interfere the adsorption of trivalent actinides on TRU resin. Therefore, trivalent iron was reduced bivalent with excess amount of ascorbic acid. Since F
interfere the adsorption of Th on UTEVA resin, Al
was generally added into the sample solution to mask F. Since Fe also can mask F, addition of Al was deleted. The developed schemes were examined with dissolved solution of stainless steel and good recovery of Th, U, Pu, and Am was obtained. Therefore, contaminated metal waste was analyzed using the scheme.

Particle analysis techniques have an important role to detect undeclared nuclear activities in nuclear safeguards. With regard to the analysis of uranium particles, we have developed SIMS and FT-TIMS methods so far. The analysis of Pu particles is also necessary in near future. In this presentation, an analytical technique using ICP-MS for individual Pu particles is presented.
