Abstract

The behavior of Ge doped silica, SiO2 Flat Fibers (FF) irradiated with 2.5 MeV electron radiation at ultra-high dose (UHD) range, up to 1 MGy, has been investigated. The analyzed glow curves measured by the usage of the WinREMS software revealed that peak height and glow curve maximum temperature are highly dependent on the dose. The shape of the glow curves is constant with increasing dose. The supralinearity of all glow peaks increases to its f(D)max, which occurs around 50 kGy. No saturation occurs at f(D)max and further increases in dose, up to 1 MGy, exhibits a significant decrease in f(D). The glow peaks 2 (230 °C) and 4 (290 °C), deconvoluted by the usage of WinGCF software, are the first-order kinetic peaks and can be used as the main dosimetric peaks for high-dose measurements between 1 and 50 kGy in an industrial environment.
