RF energy is all around us in the form of background radiation, which has existed since the beginning of the universe. Radio isn't some kind magic that humans have created; we have just learned to make use of the phenomena. Those radio bands have been used in use long enough for use to know that there are no designable health effects on people. If there were then we would expect to see higher numbers of cancers in people that own cell phones, or live close to RF transmitters. Mobile communications signals are simply not strong enough to influence the electrical signals in the brain. People are exposed to much higher levels of radiation in the form of light. In the US alone, 9500 people are diagnosed with skin cancer every day; a large number of which is caused by exposure to UV largely from the sun.
