Section 15: Health and Safety Information
This section outlines the safety precautions
associated with using your phone. The terms “mobile
device” or “cell phone” are used in this section to
refer to your phone. Read this information before using
your mobile device.
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 light, infrared radiation (heat),
and other forms of electromagnetic radiation with
relatively low frequencies.
