Microwave Leakage Testing

Microwave radiation is odourless and invisible and therefore hard to detect.

Microwave radiation is present whenever a microwave oven is turned on. Once you turn off the oven, the microwaves disappear but until then, you may be exposing yourself to dangerous levels of radiation leakage.

A survey conducted among the Professional Service Associates Рa group of microwave repair servicemen Рindicated that over 56% of microwave ovens two years or older leaked levels of radiation 10% higher than the safety standards set by the FDA. More often than not, a simple adjustment was all that was needed to stop the leakage.

Selectatest offer Microwave Leakage Testing as part of our normal PAT Testing Services. Should you require it, we can run a scan for Microwave Leakage whilst carrying out a normal PAT Test upon a microwave oven. We use specialised microwave detection equipment to scan the area immediately surrounding the microwave oven to check that the levels of radiation fall within a safe range. Should the oven leak microwaves at an unsafe level, it will fail its PAT Test with the recommended course of action being to repair or replace the appliance.

What are ‘microwaves’?

Microwaves, like visible light, are a part of the electromagnetic radiation spectrum. They are extremely high frequency radio waves. As the frequency of radiation increases, its wavelength decreases, so very high frequencies correspond to very short wavelengths; hence the name microwaves. Infrared radiation, ultraviolet light and X-rays are also electromagnetic radiations, but have even shorter wavelengths than microwaves.

Microwaves may either be reflected, transmitted or absorbed by matter in their path. Metallic materials totally reflect microwaves. Most non-metallic materials such as glass and plastics are partially transparent to microwaves. Material containing moisture, such as food and even people, absorbs microwave energy. If energy is absorbed at a rate greater than the rate at which the material loses energy (ie. rate of cooling), its temperature will increase.
