“…Except for BeO [7][8][9], these materials have not yet been adopted in dosimetry because they possess one or more undesirable features such as fading, low sensitivity to radiation, high effective atomic number, or even self-dose [10][11][12][13]. But even BeO has disadvantages: it is toxic in the powder form, so it must be used in the single ceramic form [14].…”

Fiber optical dose rate measurement based on the luminescence of beryllium oxide

Abstract-This work presents a fiber optical dose rate measurement system based on the radioluminescence and optically stimulated luminescence of beryllium oxide. The system consists of a small, radiation sensitive probe which is coupled to a light detection unit with a long and flexible light guide. Exposing the beryllium oxide probe to ionizing radiation results in the emission of light with an intensity which is proportional to the dose rate. Additionally, optically stimulated luminescence can be used to obtain dose and dose rate information during irradiation or retrospectively. The system is capable of real time dose rate measurements in fields of high dose rates and dose rate gradients and in complex, narrow geometries. This enables the application for radiation protection measurements as well as for quality control in radiotherapy. One inherent drawback of fiber optical dosimetry systems is the generation of Cherenkov radiation and luminescence in the light guide itself when it is exposed to ionizing radiation. This so called "stem" effect leads to an additional signal which introduces a deviation in the dose rate measurement and reduces the spatial resolution of the system, hence it has to be removed. The current system uses temporal discrimination of the effect for radioluminescence measurements in pulsed radiation fields and modulated optically stimulated luminescence for continuous irradiation conditions. This work gives an overview of the major results and discusses new-found obstacles of the applied methods of stem discrimination.Index Terms-Beryllium oxide, Fiber optic dose rate measurements, Optically Stimulated Luminescence, Radioluminescence I. INTRODUCTIONIBER OPTICAL DOSIMETERS (FODs) allow real time dose rate measurements with high spatial resolution. FODs consist of a small, radiation sensitive probe which is coupled to a light detection unit with a long and flexible light guide. Exposing the probe to ionizing radiation results in the emission of radioluminescence light (RL) with a characteristic spectrum and an intensity which is, under certain circumstances, proportional to the dose rate.
