Radioactive particles having highly concentrated radioactive Cs were released into the environment by the accident of Fukushima Dai-ichi Nuclear Power plant. By radiochemical analysis, the amounts of Sr and Pu in these particles were quantified. The concentrations of Sr and Pu were different by the origin of the reactors. This difference indicated the different formation process of each radioactive particle by the reactor.
