Hazards Associated with the Operation of Microwave Ovens

A review of the literature was undertaken along with a physical survey of microwave ovens being operated at USAF bases. The operation of an oven with 1 interlocks that have been jumped overridden or have failed 2 door partially or fully open represents the most serious hazard to operating personnal of these ovens, an evaluation of this situation was performed in the laboratory. Purpose of these studies was to appropriate survey procedure and equipment, and provide guidance for interpretation of survey results. It was concluded that there is very little hazard associated with the normal operation of these ovens, even though some leakage may occur. Periodic surveys of these ovens are necessary to determine if interlocks have failed or have been jumped overridden, and if significant leakage is occuring. Recommendations are made for survey procedures and equipment to be used. Levels of microwave radiation leakage which require corrective action are presented.
