As wireless technology becomes more sophisticated and accessible to more users, the interactions of electromagnetic fields with biological systems have captured the interest not only of the scientific community but also the general public. Unintended or deleterious biological effects of electromagnetic fields and radiation may indicate grounds for health and safety precautions in their use. Spanning static fields to terahertz waves, Electromagnetic Fields in Biological Systems explores the range of consequences these fields have on the human body. With contributions by an array of experts, topics discussed include: Essential interactions and field coupling phenomena, highlighting their importance in research on biological effects and in scientific, industrial, and medical applications Electric field interactions in cells, focusing on ultrashort, pulsed high-intensity fields The effect of exposure to naturally occurring and human-made static, low-frequency, and pulsed magnetic fields in biological systems Dosimetry or coupling of extremely low frequency (ELF) fields into biological systems and the historical developments and recent trends in numerical dosimetry Mobile communication devices and the dosimetry or coupling of radiofrequency (RF) radiation into the human body Exposure and dosimetry associated with magnetic resonance imaging (MRI) and spectroscopy Available data on the interaction of terahertz radiation with biological tissues, cells, organelles, and molecules There is great potential for communication, industrial, scientific, and medical use of electromagnetic fields and radiation. To help advance knowledge of the biological effects of such fields and to exploit their potential medical applications, this book highlights critical issues relating to their effects on living systems.

This book will serve as an ideal guide to the relatively new and complex field of bioelectromagnetics for students and researchers interested in the interaction of biological systems and electromagnetic fields. Coverage details:(1) biological responses of human and animals, both in vivo and in vitro methodologies, to magnetic and/or electromagnetic field exposure, (2) characteristics of effective fields, (3) hypotheses to explain possible mechanisms of interaction between the fields and cells, and (4) induced current in ELF and induced heat in RF fields as key interaction mechanisms.

Why do some people feel unwell during a lightning storm? Why is there a correlation between the level of electromagnetic background and the incidence of cancer? Why do so many medical centers use electromagnetic exposures to treat a wide variety of disorders in humans? The international scientific community is extremely interested in a theory of magnetobiology and the answers to these and other questions, as evidenced by the growing number of research associations in the United States, Europe, and other parts of the world. The World Health Organization (WHO) has named electromagnetic contamination in occupational and residential areas as a stress factor for human beings. This book stands out among recent texts on magnetobiology because it draws on a strong foundation of empirical and theoretical evidence to explain the various effects of magnetic fields on the human body.-

A comprehensive and up-to-date collection of papers on the role of electrodynamical activities in biocommunication is presented in this volume. It provides research findings, practical applications and theoretical investigations linking phenomena as diverse as the sensitivity of organisms to ultraweak ELF electromagnetic fields, noninvasive imaging by magnetic field tomography, coherent liquid crystalline mesophases in living organisms and coherent light emission from biological systems. The volume begins with chapters on the historical perspectives and the biophysical background necessary for understanding bioelectrical phenomena. This is followed by chapters dealing with the biological effects of external electromagnetic fields; the detection of endogenous electrodynamical and related activities and their practical applications; and finally, theoretical perspectives and overviews. It is recommended for undergraduates, graduates and research scientists in all disciplines who wish to be informed of the emerging discipline of bioelectrodynamics.

The possible health effects of electro-magnetic (EMF) from high-voltage electric power lines have been discussed sine the 1970s. The concern was triggered by epidemilogical studies in the United States and Europe that suggested a slightly increased incidence of leukaemia's and brain tumours occured among those living and working near high-voltage power lines. Although studies can indicate an associate between factor and effect, the studies themselves cannot confirm a cause-effect relationship. Whether EMF is producing these ill effects must be confirmed by experimental studies.

Hardly any phenomenon in the modern environment is as ubiquitous as electromagnetic fields and waves. We have learned to understand the physical characteristics of these energy forms, and we have applied them in abundant ways to embellish our ways of life and our standards of living. Furthermore, we have come to depend on them for health, safety, information, comfOli, and conveyance. Apart from their intended roles, these electromagnetic fields and waves produce other effects which may influence the activities of living organisms. The effects produced depend on many physical, chemical, and biological factors. They may be grossly apparent and visible soon after exposure of the living organism or they may not appear to have influenced the organism at all upon casual examination. Even then, there may be subtle changes which are only detectable upon careful chemical or microscopic study, or which are apparent only after a considerable time delay. Nevertheless, our understanding of the interaction of electromagnetic fields with living systems is advancing in a wide range of topical areas. This bi-annual series with invited reviews by recognized leaders in their respective specialties, will present progress to date in key areas of research and scholarship. The guiding philosophy of this undertaking is the presentation of integrated, known, and confilmed phenomenological observations, basic mechanism of interactions, and applications in biology and medicine, as well as perspectives on current topics of interest.
