英文摘要	To study the applications of Pu isotopes in long-distance dust migration monitoring, Pu isotopes in surface soil of Inner Mongolia have been analyzed using SF-ICP-MS after size fractionation. Pu-240/Pu-239 atom ratios ranged narrowly (0.169-0.200) and indicated global fallout character, while Pu239+240 activities increased with decreasing particle size. A spherical model could well simulate Pu239+240 activities as a function of particle diameter when soil particle size was less than 600 mu m, and the soil particle surface sorption phenomenon of Pu isotopes in natural soil samples was revealed. Furthermore, Pu239+240 activity in fine particles (sized less than 53 mu m) had good consistency with that in atmospheric depositions of Japan since the 2000s, suggesting new Asian Dust sources (i.e. central Inner Mongolia) other than the well-known Chinese deserts.
