Abstract:
This paper presents the experimental results obtained from studying single mode optical fiber properties, in order to develop a new radiation dosimeter sensitive to high energy photon beams. The study is based on the physical degradation effect of the optical fiber caused by irradiation with photon beams. This effect can be determined through the measurement of the radiation induced attenuation that is proportional to the exposure dose. Attenuation in the optical fiber was measured before, during and after photon beam exposure for two wavelength values. These new experimental results confirm that single mode optical fibers have a good response to radiation exposure and, therefore, can be useful in achieving the purposes of this study.
