84 FDA consumer information on wireless phones
Again, the scientific data do not demonstrate that wireless phones are harmful. But if you are concerned about the RF
exposure from these products, you can use measures like those described above to reduce your RF exposure from wireless
phone use.
What about children using wireless phones?
The scientific evidence does not show a danger to users of wireless phones, including children and teenagers. If you want to
take steps to lower exposure to radiofrequency energy (RF), the measures described above would apply to children and
teenagers using wireless phones. Reducing the time of wireless phone use and 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.
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
handsfree 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.
