摘要：

New analytical techniques using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) were applied to the determination of technetium-99 (Tc-99) and neptunium-237 (Np-237) in environmental samples. The determination of Tc-99 consists of cyclohexanone solvent extraction method to eliminate the interference isobar (Ru-99). An anion exchange with acetic acid media and a TTA-xylene solvent extraction were used fro the determination of Np-237. Technetium-95m and Np-239 were used as chemical recovery tracers in these methods. The concentrations of Tc-99 and Np-237 in the typical surface soil samples in Japan ranged from 8.1 x 10(-2) to 1.8 x 10(-1) Bq/kg-dry, from 3.3 x 10(-3) to 8.0 x 10(-3) Bq/kg-dry, respectively.
