increasing the distance between the user and the RF source will
reduce RF exposure.
Some groups sponsored by other national governments have advised
that children be discouraged from using wireless phones at all. For
example, the government in the United Kingdom distributed leaflets
containing such a recommendation in December 2000. They noted
that no evidence exists that using a wireless phone causes brain
tumors or other ill effects. Their recommendation to limit wireless
phone use by children was strictly precautionary; it was not based on
scientific evidence that any health hazard exists.
7. Do hands-free kits for wireless phones reduce risks from
exposure to RF emissions?
Since there are no known risks from exposure to RF emissions from
wireless phones, there is no reason to believe that hands-free kits
reduce risks. Hands-free kits can be used with wireless phones for
convenience and comfort. These systems reduce the absorption of
RF energy in the head because the phone, which is the source of the
RF emissions, will not be placed against the head. On the other hand,
if the phone is mounted against the waist or other part of the body
during use, then that part of the body will absorb more RF energy.
Wireless phones marketed in the U.S. are required to meet safety
requirements regardless of whether they are used against the head or
against the body. Either configuration should result in compliance
with the safety limit.
8. Do wireless phone accessories that claim to shield the head from
RF radiation work?
Since there are no known risks from exposure to RF emissions from
wireless phones, there is no reason to believe that accessories that
claim to shield the head from those emissions reduce risks. Some
products that claim to shield the user from RF absorption use special
phone cases, while others involve nothing more than a metallic
