Microwave ovens are designed to be safe when used correctly and maintained properly. They have safety mechanisms and shielding to prevent excessive microwave leakage. The United States Food and Drug Administration (FDA) sets standards for microwave oven safety, limiting the amount of microwave radiation that can leak from the oven.
According to the FDA regulations, microwave ovens must not exceed the following maximum allowable leakage levels:
5 milliwatts (mW) per square centimeter at approximately 5 centimeters from the oven surface for new ovens.
1 mW per square centimeter at approximately 5 centimeters from the oven surface for ovens in good condition after use.
These limits are considered safe for general household use. However, it's essential to note that the vast majority of microwave ovens on the market comply with these safety standards and have very low levels of leakage. When used correctly and not damaged, microwave ovens are safe to use.
To ensure microwave safety and minimize leakage, follow these guidelines:
Inspect the Door and Seals: Check the microwave door for any visible damage, and ensure it closes properly and securely. The door seals should be intact and free from debris.
Regular Maintenance: Keep your microwave clean and well-maintained. Wipe down the interior regularly to remove any spills or splatters that could affect the seals or safety features.
Avoid Physical Damage: Do not use the microwave if the door is damaged, and avoid slamming it shut or dropping heavy objects on it.
Don't Modify the Oven: Never attempt to modify or repair the microwave yourself, especially when it comes to the safety features and shielding. Always have a qualified technician handle any repairs or maintenance.
Replace Damaged Parts: If you suspect any issues with the door, seals, or other safety components, have them checked and repaired by a professional technician.
If you have concerns about microwave leakage, you can purchase a microwave leakage detector (available online or at electronics stores) to check for any potential leaks around the door and seals. If the oven fails the test or you suspect there might be a problem, stop using it immediately and have it inspected by a qualified service technician.
It's essential to use microwaves according to the manufacturer's instructions and exercise caution to ensure their safe operation.
