Non-Ionizing Radiation Used in Microwave Ovens
Microwave ovens use radiofrequency radiation in the microwave range.
• Microwaves don't make food radioactive.
• Follow the manufacturer's manual and make sure your microwave functions properly.
• Avoid standing directly against or in front of the oven while using it.
About Non-Ionizing Radiation Used in Microwave Ovens
Microwave ovens use electromagnetic waves that penetrate food, causing its water molecules to vibrate and
generate heat within the food to cook it very quickly.
The microwaves produced inside the oven are reflected by its metal interior. These reflected waves are
absorbed by food and produce heat that cooks the food.
Remember: Microwaves do not make food radioactive.
Microwave Oven
Microwave radiation leaks are hard to detect because you can't smell or
see microwaves. It is important that microwave oven doors seal properly
to make sure that the microwave radiation stays inside the oven. Old or
faulty door seals are the most common cause of leaks. Routinely
slamming the door, a buildup of dirt, or simple wear and tear can cause
door seals to leak. The U.S. Food and Drug Administration, which
regulates radiation-emitting products such as microwave ovens, advises
against standing directly in front of or up against the oven while it is
operating. This will avoid harm from any possible leaks.
Rules and Guidance
U.S. HEALTH AND HUMAN SERVICES (HHS), U.S. FOOD AND DRUG ADMINISTRATION (FDA)
FDA's Center for Devices and Radiological Health (CDRH) sets and enforces standards of performance for
electronic products that emit radiation. The standards ensure that radiation emissions do not pose a hazard to
public health. These standards can be viewed on FDA's Code of Federal Regulations on Microwave Ovens.'
FDA establishes performance standards for microwave ovens. All microwave ovens must have a label stating
that they meet these performance standards. FDA requires that all ovens have a label that explains how to use
them safely.

What you can do
• Follow the manufacturer's instruction manual and safety precautions for your oven model.
• Never operate a microwave oven if you can't shut the oven door or it doesn't seal well.
• As an added safety precaution, don't stand directly against or in front of an oven while it is operating.
