Abstract: To grasp the metrological performance indicators of the BeO optically stimulated luminescent (OSL) dosimetry system and verify whether it meets the needs of personal dose monitoring, the OSL dosemeter containing BeO optically stimulated luminescent detectors was placed in and irradiated with X-ray and γ-ray reference radiation fields. Performance test research on nonlinear response, coefficient of variation, energy response, angular response, and repeatability were carried out for the personal dose equivalent Hp(10). The nonlinear response ranged from 0.92 to 1.05 in the dose range of 50 μSv to 1 Sv, and the coefficient of variation ranged from 0.55% to 4.8%. The energy response ranged from 0.71 to 1.01 in the energy range of 33 keV to 1.25 MeV. The angular response ranged from 0.97 to 1.22 in the range of 0° to ±75° angle of incidence. The irradiation dose of 1 mSv, 5 mSv and 10 mSv were repeated 8 times, and the corresponding dose repeatability were 0.99 - 1.00, 0.99 - 1.00 and 0.97 - 1.00, respectively. The results showed that the BeO OSL dosimetry system meets the requirements of the IEC 62387-2020 standard and can be used for personal dose monitoring.
