NORFOLK, Va., (WVEC) -- A viewer asked us to Verify: Do diode stickers you put on your cellphone protect you from electromagnetic radiation?

The diodes stickers claim to shield you from the radio frequency your cellphones produce.

13News Now checked with the Federal Trade Commission. The FTC said there is "no scientific proof that these shields reduce your exposure from electromagnetic emissions." It also said the products could interfere with your phone signal and that it would actually cause it to use more power and emit even more radiation.

So we can verify that radiation diodes and shields do not work.

To limit exposure, the FTC suggests using a hands-free device or speaker phone to keep your cellphone farther from your head.
