Abstract: A technique facilitates use of radiation sampling techniques in subterranean formation environments or other environments. A radiation detector may be constructed utilize a scintillator package having a scintillating crystal. The scintillating crystal is combined with a reflector positioned to reflect light otherwise leaving a surface of the scintillating crystal. The reflector incorporates nano materials, e.g. nano particles or nano fibers, arranged to provide highly reflective properties. By way of example, the nano materials may be fabricated in a separate layer combined with the scintillating crystal or applied directly onto a surface of the scintillating crystal.
