Abstract

The radiation sensitivities of various fluoro-silica-clad step index fibers, and of germanium doped and of fluorine doped graded index fibers were measured in gamma and neutron fields. For the Fluosil types low sensitivities and a smooth dependence on the OH-content was found. Fluorine doping of the core seems not to degrade the radiation resistivity. During pulsed irradiation, a superposition of luminescense light and attenuation effects was observed. The luminescence light levels and the peak induced losses were measured as function of the gamma dose rate.
