| 内容記述 | Americium is one of the toxic radionuclides that isreleased from nuclear weapon tests and nuclear industry activities. To quickly characterize the released Am for nuclear emergency response, a new method was developed by combining HNO3 leaching, co-precipitation, extraction chromatography and SF-ICP-MS measurement; specifically, CaF2 co-precipitation is used to remove major metals, extraction chromatography by UTEVA, DGA-N and TEVA resins is used to remove interfering elements (IEs) and rare earth elements (REEs), and an Apex-ICP-MS analytical system is used to determine Am isotopes. The method was evaluated with three standard reference materials (IAEA-soil-6, IAEA-384 and IAEA-385) and the results showed that 241Am activities were accurately determined, in a short analytical time (2 days), with a high decontamination factor for the IEs (e.g. DF (Pu) = 7.4 × 105), and a high chemical recovery (63-88%). This method was further applied to analyze soil samples collected around the Sellafield nuclear complex, and high241Am activities (5.24 – 1179 mBq/g) were observed. | |||||
