Wireless communication devices emit nonionizing electromagnetic radiofrequency (RF) fields in the range of 300 MHz to 300 GHz, raising public concern regarding the increasing use of mobile phones and their potential health related risks. The intermediate frequency (IF) EMF (300 Hz to 10 MHz) is also now widely used for wireless power transmission (WPT) or domestic kitchen appliances such as induction heating cooking. Unfortunately, although plenty of research has been conducted on RF, little information exists on the potential health effects associated with the exposure to IF magnetic fields. With growing concerns regarding the potential health hazards, it has become necessary to investigate the risks of IF magnetic fields in more detail.This chapter discusses the biological effects of IF and RF exposure. This chapter is divided into the following three parts: epidemiological study, animal study, and cellular study. In the RF field, the frequency of 2.45 GHz is mainly discussed because of the future use of WPT.
