RF Radiation Exposure Limit: §1.1310: As specified in this section, the Maximum Permissible Exposure (MPE) Limit shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of Sec. 2.1093 of this chapter. RF Exposure Limits S = PG / 4π ππ πR 2 or R = √(PG / 4π ππ πS) where, S = Power Density (mW/cm 2 ) P = Power Input to antenna (mW) G = Antenna Gain (numeric value) R = Distance (cm) For Antenna Gain
