[Animal death after exposure to ultra-high frequency waves in the dependence of power flux density and specific absorption rate].
A comparative analysis and mathematical modeling of laboratory animal sensitivity (mice, rats, rabbits and dogs) to microwave exposure in the dependence of the power flux density (PFD) and the specific absorption rate (SAR) were carried out. The results obtained in our laboratory and some data published by other authors were presented as the dependence of the survival time of various animals during exposure both on PFD and SAR of microwave radiation (0.46; 2.4 and 7 GHz). It is shown that if PFD is used as a dosimetric parameter, the animal sensitivity to nonionizing electromagnetic ultrahigh frequency radiation increased with animal mass. If SAR was used as a dosimetric parameter, the arrangement of animals in accordance with their sensitivity to microwave became quite opposite. Mathematical equations describing the dependence of the survival time of laboratory animals on the duration and the intensity of microwave radiation were obtained. These equations describe the published experimental data and can be used to predict the animal death during the process of microwave irradiation.
