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.
Very high levels of electromagnetic energy, such
as is found in X-rays and gamma rays, can ionize
biological tissues. Ionization is a process where
electrons are stripped away from their normal
locations in atoms and molecules. It can
permanently damage biological tissues including
DNA, the genetic material.
The energy levels associated with radio
frequency energy, including both radio waves
and microwaves, are not great enough to cause
ionization of atoms and molecules. Therefore, RF
energy is a type of non-ionizing radiation. Other
types of non-ionizing radiation include visible
