What kinds of phones are the subject of this update?
The term wireless phone refers here to hand-held 
wireless phones with built-in antennas, often called 
"cell," "mobile," or "PCS" phones. These types of wireless 
phones can expose the user to measurable radio 
frequency energy (RF) because of the short distance 
between the phone and the user's head. These RF 
exposures are limited by Federal Communications 
Commission safety guidelines that were developed with 
the advice of FDA and other federal health and safety 
agencies. When the phone is located at greater distances 
from the user, the exposure to RF is drastically lower 
because a person's RF exposure decreases rapidly with 
increasing distance from the source. The so-called 
"cordless phones," which have a base unit connected to 
the telephone wiring in a house, typically operate at far 
lower power levels, and thus produce RF exposures well 
within the FCC's compliance limits.
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 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. Many studies of low level 
RF exposures have not found any biological effects. Some 
studies have suggested that some biological effects may
