Implementation of an integrated detection system for contamination monitoring of respirators has been problematic. Because of the complex surfaces, hand monitoring using portable survey instrumentation has been the preferred method. Hand monitoring is costly in time and often fails to reliably achieve a given detection limit because of variables such as survey speed and distance from the probe. There is a need for a monitoring system for respirators that is easy to use and calibrate. In Phase II of this research we plan to develop two full scale prototype monitors based on modularized position sensitive detectors. These detectors represent a logical amalgamation of discrete detectors and continuous position sensitive units. Once constructed, the prototype monitors will be deployed at a commercial nuclear laundry facility for testing and evaluation.
Anticipated Results:After field testing of the two prototypes, the lessons learned will be applied toward commercialization of the monitor system that was deemed to be of the best overall design. Other potential applications of the modular position sensitive detector technology include contamination monitors for other items having irregular surface features that have proved difficult in the past to properly survey. Such monitors could find use in industrial settings, medical facilities and research laboratories.
