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 scientific 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
range. They also emit RF at substantially reduced time intervals when in the
stand-by mode. Whereas high levels of RF can produce health effects (by heating
tissue), exposure to low level RF that does not produce heating effects causes no
known adverse health effects.
The biological effects of radio frequency energy should not be confused with the
effects from other types of electromagnetic energy.
