14, - 14 - Microwave Oven Leakage With time, microwave leakage around door seals, hinges and metal fittings is not uncommon. Therefore, it is important that all microwave ovens be periodically checked to ensure that no damage or malfunction has occurred. Microwaves may easily pass through porcelain, glass, ceramics and most plastics. Highly potent microwave energy generated by microwave ovens is also capable of penetrating living tissue to a depth of approxim…
