Hi all. I have heard that cell phones heat up the brain, when you are talking in one because of the EM-waves at ~800-900 MHz. Now the transmitter of a radio station at e.g. 100 MHz sends out EM-waves at a frequency of 100 MHz in all directions. Does this mean that all our brains are being heated up by the waves coming from the radio station? Also, do these waves get weakend by scattering?
