摘要

Abstract

The Chinese Institute for Radiation Protection (CIRP) has been equipped with a 300 kV multi-nuclide low-energy accelerator mass spectrometer system (MILEA)

which is capable for ultra-low level measurements for 14C

129I

actinide nuclides (Pu isotopes

237Np

Am isotopes

Cm isotopes and U isotopes) in various sample matrices. In the on-site acceptance test and tuning measurement of the system

it was shown that the system has the excellent performance to determine 14C

129I and actinide nuclides with key parameters including the transmission efficiency from injector to detector

the current intensity in the high-energy side

the ratios of rare radionuclides and stable nuclides or/and abundance sensitivity in blank samples

and the scatter obtained from multiple standard targets. The results obtained show that the system is competitive with larger AMS systems.
