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
energy (RF) in the microwave range
while being used. They also emit
very low levels of RF when in the
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,
other researchers have had difficulty
in reproducing those studies, or
in determining the reasons for
inconsistent results.
