Further testing of pocket-sized electronic dosimeters

The experiences of industrial radiographers have indicated that electronic radiation-warning devices become inoperative when they are used under some types of ambient conditions. This report, documents the nature of tests performed on several additional commercially available models. None of the three models tested passed the tests for ruggedness and severe environmental conditions. However all models passed most of the requirements of a Health Physics Society draft standard of performance specifications for these devices. The test procedures used in the project and the results obtained are discussed. Conclusions from the tests and recommendations concerning potentially useful modifications to existing devices are presented
