Lightguide-coupled sensor for in-situ radiation monitoring
The authors are developing a multi-point radiation monitoring system for long-term, continuous monitoring of radiation levels in the vadose zone of radioactive waste sites. The system is based on gamma detection with a lightguide-coupled scintillator built into a probe buried in the ground. The lightguide transmits the visible light pulses produced by the scintillator to the surface where detection and signal multiplexing take place. The system is to be capable of monitoring large numbers of such passive probes which are to be permanently installed throughout the waste site. The authors have recently completed tests of a prototype single-probe system. In this paper, they report on the development and testing of the single-probe system.
