Frequencies considered especially dangerous occur where the human body can become resonant, at 35 MHz, 70 MHz, 80-100 MHz, 400 MHz, and 1 GHz. https://en.wikipedia.org/wiki/Radiation_burn https://en.wikipedia.org/wiki/Radiation_burn At frequencies near the body's natural resonant frequency, RF energy is absorbed more efficiently, and maximum heating occurs http://www.arrl.org/rf-radiation-and-electromagnetic-field-safety http://www.arrl.org/rf-radiation-and-electromagnetic-field-s...
