Advancements in understanding RFR interactions with living systems, based on dosimetry and biological-effect research, are shared throughout the world. Differences in RFR safety guidelines established by different governmental bodies depend largely on the degrees of conservatism applied and philosophical approaches taken. These facts are well documented in current reviews of RFR-induced biological effects. New research to assess biological effects of RFR exposure has emerged rapidly and in considerable quantity over the past 5 years. The vast majority of reported effects are related to thermal insults from incident average power densities greater than 2 mWsq. cm. When analyzed in terms of SAR as a common denominator, effects appear at threshold values near 4 Wkg. The new RFR safety guidelines and their rules of application clearly provide greater safety than those used in the past. They have a more credible scientific basis and are supported by the overwhelming majority of current research findings.
