Response of personal dosemeters to high energy photon radiation is of great interest nowadays due to a spread of new radiation
technologies and the expansion of occupational exposure domains. ICRU95 publication has expanded the range of relevant photon
energies upwards, setting new horizons for individual monitoring. Beryllium oxide (BeO) material is increasingly popular due to its
excellent optically stimulated luminescence (OSL) properties, simple readout and reasonable energy response in the low energy
(below 100 keV) range. The study considers energy dependence of OSL response at higher photon energies. Energy deposition
of monoenergetic photons with energy up to 15 MeV in the BeO chips of various thickness was modeled with Monte Carlo MCNP
6.2 code. Benchmark experiments were conducted at LINAC with high voltage of 6, 10 and 15 MV resulting in respective incident
photon spectra. The findings of this study add knowledge regarding behavior of BeO personal dosemeters in the photon fields
within the energy range above 3 MeV.
