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
