| 内容記述 | Internal contamination with alpha-particle emitting actinides, such as 238U, 237Np, 239Pu, 240Pu, is likely to bring a large radiation exposure dose to the patient even if the intake amount is small. In order to provide timely information for prompting decision making in radiation emergency medicine, we attempted to develop a simple and rapid method based on the analysis of ultra-trace level of U, 237Np and Pu isotopes in a small amount of urine samples (20–100 mL) by the SF-ICP-MS and the ICP-MS/MS. A simple single chromatographic column packed with 2 mL AG MP-1M resin (100–200 mesh, chloride form, Bio-Rad, Hercules, CA, USA) was used for the separation of targeted isotopes from the matrix elements and other potential interferences. Uranium isotopes were measured using 233U as a yield tracer with a yield of ca. 10%. To avoid polyatomic and tailing effects from U, 237Np and Pu isotopes were collected after U fraction and measured using 242Pu as a yield tracer with a yield of ca. 70%. Finally, the proposed method was applied to the contaminated urine samples during the Pu inhalation accident occured at JAEA in 2017. | |||||
