Simple way to check microwave oven radiation leakage

Put your phone in the microwave and try calling, if it rings it means the device may not be completely blocking the radiation.

Microwave ovens are now one of the familiar electronic appliances in many families' kitchens. However, many people are still afraid of the risk of radiation leakage from this modern cooking device.

In principle, microwave ovens use microwaves (microwaves), a type of wave with a wavelength shorter than radio waves but longer than infrared rays, to cook food by transferring energy to the water molecules in the food. Therefore, the food will be heated both inside and outside. However, this type of wave can be harmful to humans.

Most appliances such as microwave ovens undergo rigorous testing before reaching the consumer. However, over time or physical factors can cause the appliance to leak this dangerous type of wave.

According toIInterest Engineering, kA YouTube channel called Physics Girl has come up with a simple experiment for users to test their devices themselves.

Because microwave ovens, like cell phones, emit radiation in a specific frequency range. Therefore, users can test by placing their phone in the microwave and closing the door. If the signal is blocked when trying to call, and cannot ring, it means the microwave oven is safe.

While testing a device, Physics Girl discovered that some microwaves did not block phone signals. Further testing revealed that the leak was mainly from the door. It seemed that repeated use and opening and closing had compromised the airtightness of the device.Of course, these experiments were performed on small sample sizes, without taking into account “age” and distance from the device to the mobile phone.

In fact, users do not have to worry too much about this leak.The US Food and Drug Administration (FDA) regulations allow a small amount of microwave radiation to leak from microwave ovens, about 5mW/cm2.

If large enough, bAlthough this radiation does not directly affect human DNA, it will stimulate water in the soft tissues of the skin, causing burns.Body parts such as the eyes and testicles are particularly vulnerable because they have less blood flow and are less able to cool down. However, in comparison, users are more likely to injure themselves becauseA cup of hot water is more than the radiation from your microwave.
