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.
8 Important Health and Safety Information
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.
Research Results to Date: Is there a
connection between RF and certain
health problems?
The results of most studies conducted
to date say no. In addition, attempts to
replicate and confirm the few studies that
have shown a connection have failed.
The scientific community at large therefore
believes that the weight of scientific
evidence does not show an association
between exposure to Radio Frequency
(RF) from cell phones and adverse health
outcomes. Still the scientific community
has supported additional research to
address gaps in knowledge. Some of these
studies are described below.

Interphone Study
Interphone is a large international study
designed to determine whether cell
phones increase the risk of head and
neck cancer. A report published in the
International Journal of Epidemiology
(June, 2010) compared cell phone usage for
more than 5,000 people with brain tumors
(glioma and meningioma) and a similar
number of healthy controls.
Results of this study did NOT show that cell
phones caused brain cancer. In this study,
most people had no increased risk of brain
cancer from using cell phones. For people
with the heaviest use of cell phones (an
average of more than ½ hour per day, every
day, for over 10 years) the study suggested
a slight increase in brain cancer. However,
the authors determined that biases
and errors prevented any conclusions
being drawn from this data. Additional
