"Microwave ovens don’t make foods radioactive. They just heat them. Microwave ovens heat food by producing radiation which is absorbed by water molecules in the food. This makes the water molecules vibrate and produce heat, which cooks the food.
Any modern day microwave oven in good condition is perfectly safe as long as you follow the instructions for use. If you use a microwave oven in the correct way there is no known harmful effect on humans. But people still tend to worry. Understanding the different types of radiation may help to reassure you that cooking in a microwave is not dangerous and won’t cause cancer."
