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.
While RF energy does not ionize particles,
large amounts can increase body
temperatures and cause tissue damage.
Two areas of the body, the eyes and the
testes, are particularly vulnerable to RF
heating because there is relatively little
blood flow in them to carry away
excess heat.
