UV–Visible reflectance of common light reflectors and their degradation after an ionization dose up to 100 Mrad


Light reflectors are widely used to enhance scintillation light collection. Their enhancement level depends on the reflector's reflectance at the scintillator's emission wavelength. We report UV–Visible reflectance spectra, relative to BaSO₄, for several common reflectors. Also reported is their radiation hardness against an ionization dose up to 100 Mrad. The results of this investigation provide a reference for applications of these reflectors in a severe radiation environment.
