| Research Abstract |
Accelerator mass spectrometry (AMS) is a method of measuring extremely low ratios of isotopes in a very small sample of less than 1 mg. In particular, AMS measurements for 14C, which has a half-life of 5730 years, have been widely utilized for radiocarbon dating in various fields such as archaeology, environmental science, geology, medical and pharmaceutical areas, and space and earth sciences. The performance tests of the YU-AMS system were carried out by measuring the standard and dendrochronology samples. The results show that the YU-AMS system enables the precise and stable measurements of 14C concentration for these samples.
