Hands-Free Kits
Hands-free kits may include audio or Bluetooth® headsets and various types of body-worn accessories such as
belt-clips and holsters. Combinations of these can be used to reduce RF energy absorption from cell phones.
belt-clips and holsters. Combinations of these can be used to reduce RF energy absorption from cell phones.
Headsets can substantially reduce exposure because the phone is held away from the head in the user's hand or in
approved body-worn accessories. Cell phones marketed in the U.S. are required to meet RF exposure compliance
requirements when used against the head and against the body.

Because there are no known risks from exposure to RF emissions from cell phones, there is no reason to believe
that hands-free kits reduce risks. Hands-free kits can be used for convenience and comfort. They are also required
by law in many states if you want to use your phone while driving.

Cell Phone Accessories that Claim to Shield the Head from
RF Radiation
RF Radiation
Because there are no known risks from exposure to RF emissions from cell phones, there is no reason to believe
that accessories which 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 in RF absorption.

Children and Cell Phones
The scientific evidence does not show a danger to any users of cell phones from RF exposure, including children
and teenagers. The steps adults can take to reduce RF exposure apply to children and teenagers as well.

•
Reduce the amount of time spent on the cell phone;
•
Use speaker mode or a headset to place more distance between the head and the cell phone.
Some groups sponsored by other national governments have advised that children be discouraged from using cell
phones at all. For example, The Stewart Report from the United Kingdom made such a recommendation in
December 2000. In this report, a group of independent experts noted that no evidence exists that using a cell phone
causes brain tumors or other ill effects. Their recommendation to limit cell phone use by children was strictly
precautionary; it was not based on scientific evidence that any health hazard exists.
