内容記述 | Radiostrontium measurement is possible using radiometric or mass spectrometry methods. Thermal Ionization Mass Spectrometer (TIMS) is a very sensitive device however it was not used to measure radiostrontium. Applying TIMS, three criterions have to be fulfilled: - adequate peak resolution - adequate abundance sensitivity - efficient chemical separation with high recovery. In our work the fulfillment of these criterions were tested and confirmed. The peak of the Sr-90 was distinguishable from the other Sr isotopes. The ion beam was stable resulting good quality plateau peak for Sr-90. The result of abundance test also was acceptable, m/z 90 relative to m/z 88 was <4e-8 that means about 100 fg or 5 mBq detection limit for Sr-90 pro sample. Applying our chemical separation methods, efficient elimination of the disturbing elements was accomplished with around 80% Sr recovery. |
