| 内容記述 | In this study, we report 237Np and Pu isotopes in soil, riverbed and reservoir sediments after the Fukushima Dai-ichi Nuclear Power Station (FDNPS) accident. 237Np activities in these samles were (0.013±0.02)~(5.7±1) mBq/kg-dry and were one to three orders of magnitudes low compared to these previous reports before the FDNPS accident even considering radiation decay. 237Np activities were generally three orders of magnitude lower than those of 239+240Pu activities. We will also report 237Np and Pu isotopes activity and atomic ratio and what we learn from them and relationship between these transuranic elements and Cs isotopes. This work was partially supported by Research and Development to Radiological Sciences in Fukushima Prefecture. |
