ABSTRACT
This chapter considers some questions of dosimetry for which solutions are necessary by studying the mechanisms of biological effects of extremely high-frequency electromagnetic radiation (EHF EMR). The purpose of dosimetry is to establish a relationship between parameters of external electromagnetic fields (EMF) influencing a biological object and parameters of the fields penetrating to the exposed system, leading to primary biological effects. In certain experimental conditions, the study of biological effects of EHF EMR raises the following issues: choosing a radiating system, matching of a radiator with feeding tract and exposed biological object, measuring the radiation pattern of an antenna, determining an IPD, measuring distribution of SAR in the irradiated object, and assessing a degree of heterogeneity of SAR, dependence on radiation frequency, and geometry of the irradiated object. The chapter summarizes the results of works devoted to dosimetric supply of experiments directed to studying the mechanisms of EHF EMR effects at different levels of organization of biological objects.
