Do hands-free kits for devices reduce risks from exposure
to RF emissions?
Since there are no known risks from exposure to RF emissions from
devices, there is no reason to believe that hands-free kits reduce risks.
Hands-free kits can be used with devices for convenience and comfort.
These systems reduce the absorption of RF energy in the head because
the device, which is the source of the RF emissions, will not be placed
against the head. On the other hand, if the device is mounted against
the waist or other part of the body during use, then that part of the
body will absorb more RF energy. Devices 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 device accessories that claim to shield the head from RF
radiation work?
Since there are no known risks from exposure to RF emissions from
devices, 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 device cases,
while others involve nothing more than a metallic accessory attached
to the device. 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 device. The device 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 device
users from radiation with making false and unsubstantiated claims.
