This 1978 study compared how electromagnetic energy from portable radios penetrates human tissue at two different frequencies: 450 MHz versus 800-900 MHz. Researchers found that higher frequencies (800-900 MHz) deposit more energy in surface tissue layers, while the curved shape of the human head actually focuses this energy deeper into brain tissue than the lower 450 MHz frequency.
