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 need for an easily used and calibrated monitoring system for respirators. In Phase I of this research, we propose to study three diverse approaches to respirator monitoring: proportional counters, plastic scintillators, and liquid scintillators. The most promising approach would be more fully developed in Phase II of the project.
Anticipated Results:After determination in Phase I of the best overall system for a field reliable respirator monitor, Phase II funding will permit development of a full scale working unit for field application and testing in appropriate nuclear installations. Commercialization of the respirator monitor will follow. Other potential applications include specific shaped laboratory and nuclear medicine monitors to benefit both research and medical communities.
