k 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.
k 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 “hands-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
