Exposure To Radio Frequency (RF) Signals
The U.S. Food and Drug Administration (FDA) has published information for
consumers relating to Radio Frequency (RF) exposure from wireless phones. The
FDA publication includes the following information:
Do cell phones pose a health hazard?
Many people are concerned that cell phone radiation will cause cancer or other
serious health hazards. The weight of scientic evidence has not linked cell
phones with any health problems.
Cell phones emit low levels of Radio Frequency (RF) energy. Over the past 15
years, scientists have conducted hundreds of studies looking at the biological
effects of the radio frequency energy emitted by cell phones. While some
researchers have reported biological changes associated with RF energy, these
studies have failed to be replicated. The majority of studies published have
failed to show an association between exposure to radio frequency from a cell
phone and health problems.
The low levels of RF cell phones emit while in use are in the microwave frequency
