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 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.
