In 2021, the National Research Institute of Cultural Heritage (NRICH) installed a new accelerator mass spectrometer (AMS) to date Korean national heritage. Before conducting radiocarbon dating, the facility was set up and its performance was assessed. AMS system parameters have been optimized. Measurement of standard and blank samples was verified. Intercomparison analyses were also performed using heritage samples. The F14C value of NIST 4990C was 1.3406 and the background level was 0.0024. Both IAEA-C7 and C8 were confirmed to match the reference value within the 1-σ range. The NIST 4990C measurement results confirmed high precision and accuracy, with 1-σ values below 2‰. In the intercomparison, the error for each sample was 2‰. Thus, based on this study, NRICH plans to launch a dating service specializing in cultural heritage.
