The most common biological effect of overexposure to radiofrequency radiation RFR fields may be described as an acute thermal burden. The extent of the effect depends primarily on the time rate of transfer of the energy to the biological specimen. The depth of penetration and the amount of incident energy absorbed varies as a function of the frequency of the incident radiation. As the frequency decreases, the penetration of energy into biological tissue becomes deeper however, wavelengths in the kilohertz kHz and lower megahertz MHz regions are so long with respect to the physical dimensions of the human subject that energy absorption is negligible. The purpose of this research was to measure the energy absorption in human phantoms when exposed to high frequency HF band fields.
