Cell Phone Accessories that Claim to Shield the Head from RF Radiation
Because there are no known risks from exposure to RF emissions from cell phones, there is no reason to believe that acces-
sories 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, lead-
ing 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.
