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.
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.
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.

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 light, infrared radiation (heat), and other forms of
electromagnetic radiation with relatively low frequencies.
