ABSTRACT
Electromagnetic fields (EMFs) in the intermediate frequency (IF) range (3 kHz–10MHz) share characteristics with extremely low-frequency (ELF) and radiofrequency (RF) EMF. Several physical quantities are used to measure high-frequency EMF, including power density, electric field strength or E-field, and magnetic field strength or H-field. Other quantities used to characterize RF EMF are specific absorption (SA) and specific absorption rate (SAR). These quantities describe the RF EMF dose and dose rate, respectively, as they refer to the amount of energy absorbed by the body or any other matter. The chapter describes several RF and IF EMF sources, including information on the levels of exposure to electric and magnetic fields associated with them. These estimates of exposure intensity were obtained by combining information from many literature resources, as part of the INTEROCC project. The RF and IF EMF sources included were identified in this study as the most common EMF sources in everyday environments. They have been grouped according to their use/application.
