The RRPG provides recommended guidelines used when a person uses radio waves and whose body is exposed to an electromagnetic field (in a frequency range of 10 kHz through 300 GHz) to ensure that the electromagnetic field is safe without producing an unnecessary biological effect on the human body. These guidelines
