The FCC also regulates the base stations that the wireless phone networks rely upon. While
these base stations operate at higher power than do the wireless phones themselves, the RF
exposures that people get from these base stations are typically thousands of times lower than
those they can get from wireless phones. Base stations are thus not the subject of the safety
questions discussed in this document.
2. Do wireless phones pose a health hazard?
Current 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 while operating microwave ranges
(which also emit very low levels of RF when they are in standby mode). While high levels of
RF can produce health effects (by heating tissue), exposure to low-level RF that does not
produce heating effects results in no known adverse health effects. Many studies of low-level
RF exposures have not uncovered any biological effects. Although some studies have
suggested that some biological effects may occur, such findings have not been confirmed by
