An accelerator mass spectrometry has been set up at the Mutsu Establishment of Japan Atomic Energy Agency. This AMS has two independent beam lines, optimized for 
C and 
I measurements. For the I measurement, precision and reproducibility was 2.0 - 1.5% and 1.5 - 0.7%, respectively at the acceptance test in July 2000, and after that, exchange of MCP and re-alignment improved precision and reproducibility to 0.6% and 0.26%, respectively. The results of testing standard materials, which have a variety of iodine isotopic ratios (I/
I), showed that this beam line has excellent measurement accuracy between 10
and 10
iodine isotopic ratios, and the detection limit is substantially below the 10
iodine isotopic ratio. Sub-standard samples were normalized to NIST SRM 3230 standard reference material, and the iodine isotopic ratio was (1.21
0.01)
10 for Iso Trace Lab. Standard, (7.220.03)10
for Standard No. 3K and (2.770.03)10 for Standard No. 3i.
