ABSTRACT
During the past two decades, environmental radiofrequency (RF) exposure has increased tremendously due to the rapid development and widespread use of wireless communication technologies such as mobile telephony, wireless networking, radar systems, TV and radio broadcasting, microwave ovens, and so on. This chapter presents the fundamental physical aspects of RF radiation, which are essential for conducting practical RF dosimetric measurements and understanding the effects of RF radiation exposure. By measuring the densitometric RF field parameters, it is possible to only estimate the intensity of RF radiation in free space, thereby enabling the determination of the possible risks from RF radiation exposure. The existence of thermal effects is scientifically proven and is the subject of numerous studies whose primary objective is to determine the exact consequences of thermal effects of RF radiation and measures for the protection of the same.
