Model		Review of Russian bioeffects studies and the use of power flux density vs. SAR for exposure assessment
Details		(summary from text, extracted & consolidated): The traditional way in Russia for the description of microwave effects is to show their dependence on power flux density. As has become obvious, such a representation is not only insufficient, but also can be the reason for faulty conclusions and inadequate extrapolation. The most acceptable parameter for a quantitative estimation of microwave effects is the specific absorption rate (SAR). The methods of experimental and theoretical numerical determination of the average SAR are widely used in various countries; however, similar works in Russia are absent. This paper describes the original calorimetric devices and the results of dosimetric measurements of the average SAR for various laboratory animals (mice, rats, rabbits and dogs), frequencies (0.46, 2.4 and 7 GHz) and polarizations (E, H and K). Experimental support for the authors' viewpoint on the use of power flux density versus SAR is provided by data on survival of mice, rats and rabbits exposed at 7 GHz over a range of power flux density (0.08-25 W/cm2) and SAR (~5-5000 W/kg). From these data, SARs associated with survival times of 70-90 min can be estimated to be ~5-6, 14 and 30 W/kg for rabbits, rats and mice, respectively. Higher SARs reduced survival time for all species.
