Abstract
Provided are transparent molded bodies for use as a scintillator for measuring the type and intensity of ionizing and non-ionizing radiation, including an organic polymer and, if desired, at least one additive which, under the influence of at least one of ionizing and non-ionizing radiation, emits scintillation radiation in the range from UV to IR light, the aim is to improve optical and mechanical properties, robustness against, environmental influences and the manufacturability. This was achieved in that the organic polymer at least in part contains a polyaddition product of polyfunctional isocyanates and one or more polyfunctional hardener components.
