ABSTRACT:
A skin equivalent structure is formed from an aluminized polyester window and a scintillator. The scintillator is chosen to scintillate at a wavelength different from that of most Cerenkov light. The scintillator light travels through a light pipe and one or more filters to a photomultiplier tube. Beta particles reaching the scintillator provide light that results in an electrical output from the tube that corresponds to the skin beta dose rate. The filters are chosen to remove the Cerenkov light. In addition, the light pipe may also be chosen to attenuate the Cerenkov light.
