The measurement method for some radioisotope such as 99Tc, 182Hf, 151Sm is developing in China Institute of Atomic Energy (CIAE) accelerator mass spectrometry (AMS) system, and applications in the fields of nuclear physics, geosciences, life science and materials science is carried out. The brief introduction of these methods and applications are described in this paper.
The measuring method of irradiated enriched Hf isotope abundance ratio ^181Hf/^180 Hf and ^182Hf/^180Hf using thermal ionization mass spectrometry (TIMS) was introduced. At the same time, elimination the isobaric interference of ^182W in the measurement was discussed. The results of preliminary study have been obtained.
