Microwaves, Radio Waves, and Other Types of Radio-frequency Radiation

Although RF radiation does not cause cancer by damaging DNA in cells the way ionizing radiation does, there has been concern that some forms of non-ionizing radiation might have biological effects that could result in cancer.

In the US, federal standards limit the amount of radiation that can leak from a microwave oven to a level far below what would harm people.

But, microwave ovens that are damaged or modified allow microwaves to leak out, and so could pose a hazard to people nearby.

Man-made RF radiation is used for many different things, such as

- Broadcasting radio and television signals.
- Transmitting signals from cordless telephones, cell phones and cell phone towers.
- WiFi and Bluetooth
- Cooking food (in a microwave oven)
- Heating body tissues to destroy them in medical procedures
