Update on Mobile Phones:
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
