Microwaves that are in proper working condition and well-maintained should not leak harmful levels of microwave radiation. Modern microwave ovens are designed with safety features and shielding to prevent microwave radiation from escaping the cooking chamber while the oven is in use.
However, microwave ovens are subject to regulations and standards that dictate the maximum allowable radiation leakage. These regulations vary by country and are set to ensure consumer safety. When a microwave oven undergoes testing and certification, it must comply with these standards to be considered safe for use.
Under normal circumstances, microwave ovens do not emit significant levels of radiation beyond the allowable limits. So, you should not be concerned about microwave ovens in your home or neighboring homes leaking harmful radiation.
However, it's essential to note that microwave ovens can deteriorate or become damaged over time. If a microwave oven is not properly maintained, if the door or seal becomes faulty, or if there is significant physical damage to the microwave, it may lead to radiation leakage. This is why it's crucial to follow the manufacturer's guidelines, have the microwave serviced by qualified technicians if needed, and replace the unit if there are signs of significant damage.
If you suspect that a microwave oven is leaking radiation, you can purchase a microwave radiation leakage detector (available online or in specialized stores) to measure any potential leakage. If you find any concerning readings or suspect an issue, it's best to discontinue using the microwave and seek professional assistance. Always prioritize safety when using any household appliances, including microwave ovens.
