Low-energy X-ray Angular Response of Optically Stimulated Luminescent Dosimeters
Abstract
Following the requirements of radiation protection international standards, passive dosimetry systems are type tested, which includes the angular dependence. As it represents one of the most important dosimeter characteristics, the angular dependence of commercially available optically stimulated luminescent dosimeters has been examined in this paper. The empirically determined air kerma to the personal dose equivalent conversion coefficients decrease as the angle of incidence increases. It was anticipated that the dosimeter response would show a similar behavior. This expectation has been confirmed for all the used angles of incidence and energies of the primary X-ray beam, except for the 80° angle of incidence and the 33 keV and 48 keV mean photon energies, where an increase in the angular response has been observed.
