the available scientific evidence does not demonstrate any adverse health effects
associated with the use of mobile phones.
What kinds of phones are in question?
Questions have been raised about hand-held mobile phones, the kind that have a
built-in antenna that is positioned close to the user's head during normal telephone
conversation. These types of mobile phones are of concern because of the short
distance between the phone's antenna--the primary source of the RF--and the
person's head. The exposure to RF from mobile phones in which the antenna is
located at greater distances from the user (on the outside of a car, for example) is
drastically lower than that from hand-held phones, because a person's RF exposure
decreases rapidly with distance from the source. The safety of so-called “cordless
phones,” which have a base unit connected to the telephone wiring in a house and
which operate at far lower power levels and frequencies, has not been questioned.
How much evidence is there that hand-held mobile phones might be harmful?
Briefly, there is not enough evidence to know for sure, either way; however, research
efforts are on-going. The existing scientific evidence is conflicting and many of the
studies that have been done to date have suffered from flaws in their research
methods. Animal experiments investigating the effects of RF exposures
characteristic of mobile phones have yielded conflicting results. A few animal
studies, however, have suggested that low levels of RF could accelerate the
