Abstract

The Ionizing Radiation Metrology Laboratory of Indonesia’s National Metrology Institute participated in an international intercomparison of air kerma from the narrow-spectrum protection-level X-ray beam quality N-60 and N-80, as part of quality assurance efforts and preparation for expanding service scope. The measurements used X-ray beams based on the International Atomic Energy Agency (IAEA) Safety Report Series (SRS) No.16 for the N-60 and N-80 beam qualities, in accordance with ISO 4037, and under irradiation conditions specified by the intercomparison protocol from the Office of Atoms for Peace, Thailand (OAP). The air kerma rates measured from the experiments were used to determine the irradiation durations for the optically stimulated luminescence dosimeters (OSLDs). The results showed good agreement with the reference values. The mean air kerma deviated from the 2 mGy reference value by −0.63% for N-60 and −3.25% for N-80, both within the expanded measurement uncertainty of the laboratory (3.43% and 3.38%, k = 1.96). These results supported the laboratory’s technical competence in radiation protection measurements and provided a basis for expanding its calibration service scope.
