“Several standard-setting organizations have evaluated the data on biological effects and have determined that a threshold SAR of about 4 W/kg averaged over the whole body is the level at or above which adverse health effects may occur in human beings. This SAR is equivalent to about 2.5 times the resting energy production rate of the human body. Organizations that have used 4 W/kg as a basis for standard-setting include the ANSI (ANSI, 1982), the IEEE (ANSI/IEEE, 1992), the National Council on Radiation Protection and Measurements (NCRP, 1986), the American Conference of Governmental Industrial Hygienists (ACGIH, 1993), the National Radiological Protection Board (NPRB, 1993), and the International Radiation Protection Association (IRPA, 1993). However, in 1984 the U.S. Environmental Protection Agency (Elder and Cahill, 1984) concluded that:

the review of the currently available literature on RF radiation provides evidence that biological effects occur at an SAR of about 1 W/kg; some of them may be significant under certain environmental conditions.” Therefore, although biological effects may occur at SARs in the range 1 to 4 W/kg, 4 W/kg is the consensus threshold level of potentially harmful effects.”
