Health and Safety Information 3
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.
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.
