Abstract:
A new compact accelerator mass spectrometer(AMS) facility, used for
14C,
129I,
239Pu, etc. measurement, has been successfully established by China Institute of Atomic Energy(CIAE) recently. As
129I is a commonly used nuclide for environmental tracing, the performance of
129I measurement is crucial for the applications of the facility. After systematic research,
129I measurement technologies of the compact AMS has been established. The measurement sensitivity and the measurement accuracy of
129I/
127I reached to 1.5×10
-14 and 0.81%, respectively. The measurement results show that the compact AMS has reached the international advanced level and can lay the solid foundation for the application of
129I in fields like nuclear environmental monitoring and marine pollution tracing.
