Is RF hazardous to humans and/or the environment?
Thermal waves are the only electromagnetic waves confirmed as a biological hazard. This hazard stems from the fact that radio waves can heat biological material (this is how microwave ovens work). Although observed, non-thermal effects have not proven harmful. The FCC establishes legal power limits for cellular telephones, hand-held radios, and any other transmitters the public might come in contact. These limits are well below the power levels that prove to have any harmful effects, and the legal presumption is that any transmitter operating in compliance with the FCC regulations is safe. Readers concerned about the safety of wireless devices should consult the following references: EMF-Link — A biomedical science and engineering clearinghouse of information on the biological and health effects of EMF from commonly used appliances.
