This reference explores the sources, characteristics, bioeffects, and health hazards of extremely low-frequency (ELF) fields and radio frequency radiation (RFR), analyzing current research as well as the latest epidemiological studies to assess potential risks associated with exposure and to develop effective safety guidelines. Compiles reports and investigations from four decades of study on the effect of nonionizing electromagnetic fields and radiation on human health Summarizing modern engineering approaches to control exposure, Electromagnetic Fields and Radiation discusses: EM interaction mechanisms in biological systems Explorations into the impact of EM fields on free radicals, cells, tissues, organs, whole organisms, and the population Regulatory standards in the United States, Canada, Europe, and Asia Pacific Evaluation of incident fields from various EM sources Measurement surveys for various sites including power lines, substations, mobile systems, cellular base stations, broadcast antennas, traffic radar devices, heating equipment, and other sources Dosimetry techniques for the determination of internal EM fields Conclusions reached by the Food and Drug Administration, World Health Organization, and other institutions6.3 RADIO AND TELEVISION TRANSMITTERS Radio and television broadcast stations transmit their signals via AM and FM broadcasting antennas. ... kHz band for AM radio and in the 2-806 MHz band for FM radio, and in the VHF and UHF bands for television channels. ...
