children was strictly precautionary; it was not based on scientific
evidence that any health hazard exists.
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.
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
accessory attached to the phone. Studies have shown that these
products generally do not work as advertised. Unlike "hand-free" kits,
these so-called "shields" may interfere with proper operation of the
phone. The phone may be forced to boost its power to compensate,
leading to an increase in RF absorption. In February 2002, the Federal
trade Commission (FTC) charged two companies that sold devices
that claimed to protect wireless phone users from radiation with
