That claim is absurd.
1. There is currently no evidence that cell phones cause cancer. Plus, we get bombarded by a lot more RF than what our phones put out: Satellite TV and radio, wi-fi, traditional TV and radio broadcasts, GPS satellites, police radar, the radar that automatically opens doors for you at the supermarket, microwave ovens, your cable feed (runs on microwaves), ham radio, CBs from truckers and emergency vehicles, bluetooth (including headsets and fitness devices), cordless phones, wireless chargers, X-Ray machines, CT scans, walkie-talkies, even light bulbs and speakers. To think that the relatively small addition your phone ads to the mix is what pushes you over the edge doesn't hold water.
2. Radiation = Radio waves (aka RF). They are one in the same. Radiation that is proven to damage human cells is called ionizing radiation, and it is found way, way up in the RF spectrum above visible light (i.e., ultraviolet and above). The part of the spectrum used for communications by cell phones is way down in the non-ionizing range. They have made no scientific link between non-ionizing radiation and cancer.
3. Back to the claim that there are cases with additional signal receptors that minimize the RF That goes into your body...That makes no sense at all. Unless it's made of thick lead, it's not happening. These signals go through buildings, which are made of steel, wood, glass, and concrete. Nothing you put on your phone will prevent RF from passing into you. It's true that metal can hamper RF propagation ...Just lot back to the Apple antenna-gate thing. Even if they found some material that stopped RF from hitting you, it would also stop it from communicating with a cell tower.
