Abstract
A sensor which is robust for use in an industrial environment. The sensor employs two scintillation crystals to offer a sufficient crystal volume and the crystals are optically coupled through a silicone rubber compound. The compound also allows the crystals to vibrate independently so that they do not shatter. A single photomultiplier detects scintillation occurring in all the crystals.
