| Abstract: | A new analytical technique using inductively coupled plasma mass spectrometry (ICP-MS) was applied to the determination of 99Tc in some environmental samples. The accuracy and precision of the new method were assessed by comparison with those of the liquid scintillation counting method. The results obtained by ICP-MS were in good agreement with those by liquid scintillation counting at a relative deviation of 3%. The detection limit is 1.1 mBq/mL (1.73 pg/mL). |
