We are applying a screening technique with alpha-ray measurement to the analysis of particles containing nuclear materials in swipe samples. In the present study, individual plutonium particles with known purification dates prepared from a standard reference material (NBS SRM947) were measured with alpha-ray spectrometry. The obtained ( $^{241}$ Am+ $^{238}$ Pu)/ $^{239+240}$ Pu activity ratios for the particles with the diameters of less than 2 micrometers were consistent with the reference values within the uncertainties. These results indicate that alpha spectrometry can be applied to the quantitative analysis of $^{241}$ Am in individual plutonium particles.
