Mobile Phones:

1. Do wireless phones

pose a health haz-

ard?

The available scientifi c
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 fi ndings have
not been confi rmed
by additional research.
In some cases, other
researchers have had
diffi culty in reproducing
those studies, or in
determining the reasons
for inconsistent results.
