Microwave ovens are designed and manufactured to ensure that radiation leakage is minimized and remains within safe limits. When used properly, microwave ovens pose no significant health risks. However, if a microwave oven is damaged, has a faulty seal, or is not used according to the manufacturer's instructions, it is possible for radiation leakage to occur.
Exposure to excessive levels of microwave radiation can potentially cause harm, but the levels emitted by properly functioning microwaves are considered safe. The U.S. Food and Drug Administration (FDA) sets and enforces strict limits on the amount of radiation that microwave ovens can emit.
In the event that a microwave oven is leaking radiation, it's advisable to discontinue using it and have it inspected or repaired by a qualified technician. Prolonged and repeated exposure to high levels of microwave radiation could potentially increase the risk of health problems, although such cases are rare.
It's worth noting that the overall risk of cancer from microwave ovens is considered extremely low. The World Health Organization (WHO) has stated that there is no convincing evidence linking microwave oven use to cancer or any other adverse health effects when used according to the manufacturer's instructions.
To ensure your safety, it's important to follow the manufacturer's guidelines, maintain your microwave oven in good condition, and address any issues of radiation leakage promptly.
