The Reason Your Microwave Oven Door Has Mesh Grating

A microwave oven is essential in every kitchen. But have you ever wondered what the black dots on its door mean? These are part of a mesh grating that contributes to its optimal function and also performs other secondary functions. According to experts, this mesh grating is an important part of your safety.

Your Microwave Door Shields You From Radiation

Microwave ovens function by emitting radiations – don’t worry, this doesn’t make microwaved meals any less healthy! However, the machine’s door is designed to keep in electromagnetic radiation so that your food is properly heated. This is only possible due to the mesh grating lining the glass door.

The small holes in the protective mesh screen are equally spaced so that the long microwaves are kept bouncing inside the chamber. This also makes it possible for you to monitor the progress of the reheating by peering into the microwave without fearing exposure to radiation.

Should You Stand In Front Of A Microwave Door?

Yes, while you should avoid prolonged exposure to radiation, it is still safe to stand a few feet away from your microwave while it’s working. However, you must also refrain from pressing your face against its door.

An expert team conducted a study to measure the effectiveness of the microwave oven door. This was to ensure that the microwave radiation that could leak through the door is at the barest minimum. However, while there should be almost no radiation escaping from the chamber, it’s best not to press your nose up against the door the entire time your food is heating up. It’s safer to stand a safe distance away so your exposure is reduced to none.

You Risk Radiation Poisoning If The Microwave’s Mesh Grating Is Compromised

If you notice the slightest damage to your microwave oven, whether to its door or any other part of it, you may be exposed to dangerous levels of electromagnetic radiation. These are hard to detect because they don’t give off any smell. So, the U.S. Food and Drug Administration (FDA), which regulates radiation-emitting products such as microwave ovens, advises that you:

• Follow the manufacturer's instructions when operating your microwave oven and always stay alert for signs of damage.
• If you notice any damage, stop using the machine immediately.
• Don’t forget to keep your distance from the microwave when it is operating.

Remember, prevention is better than cure!
