1. Do wireless phones pose a
health hazard?
The available scientific evidence does
not show that any health problems
are associated with using wireless
phones. There is no proof, however,
that wireless phones are absolutely
safe. Wireless phones emit low levels
of Radio Frequency (RF) energy in the
microwave range while being used.
They also emit very low levels of RF
when in standby 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. Many studies
of low level RF exposures have not
found any biological effects. Some
studies have suggested that some
biological effects may occur, but such
findings have not been confirmed by
additional research. In some cases,
