Download and read online Electromagnetic Interaction with Biological Systems in PDF and EPUB Ever since the early 1940's, electromagnetic energy in the nonionizing spectrum has contributed to the enhanced quality of life in a variety of ways. Aside from their well-known roles in communication, entertainment, industry and science, electromagnetic energy has come into wide spread use in biology and medicine. In addition to the intended purposes, these energies produce other effects which have been shown to influence the life processes of living organisms. It is noteworthy that these energies are not only harmless in ordinary quantities but are actually necessary for modern life, indeed without which life as we know it would be impossible. The purpose of this book is to present a succinct summary of the interaction of electromagnetic fields and waves with biological systems as they are now known. The subject matter is interdisciplinary and is based primarily on presentations scheduled for a joint symposium at the XXII General Assembly of the International Union of Radio Science, held in Tel Aviv, Israel from Tuesday, August 25 to Wednesday, September 2, 1987. The symposium was jointly sponsored by the Bioelectromagnetics Society in cooperation with the International Radiation Protection Association. The choice of topics was made to facilitate the application and to stimulate the use of nonioni zing electromagnetic energy in biology and medicine, and to increase the awareness and to promote the consideration of radiation safety by electrical engineers and experimental physicists.

Download and read online Electromagnetic Fields in Biological Systems in PDF and EPUB 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.

Newly separated and expanded chapters describe the external and internal electromagnetic environments of organisms and recent developments in the use of RF fields for imaging. Bioengineering and Biophysical Aspects of Electromagnetic Fields provides an accessible overview of the current understanding on the scientific underpinnings of these interactions, as well as a partial introduction to experiments on the interactions themselves.
Download and read online Biological Effects of Magnetic and Electromagnetic Fields in PDF and EPUB The International Symposium on Biological Effects of Magnetic and Electrom- netic Fields was held from September 3-4, 1993 at Kyushu University in Fukuoka . Japan . Originally, it was only intended to be an informal gathering of many scientists who had accepted my invitation to visit Kyushu University after the XXIVth General Assembly of the International Union of Radio Science (URSI), held in Kyoto prior to our symposium . However, since so many distinguished scientists were able to come, it was decided that a more formal symposium would be possible . It was a very productive symposium and, as a result, many of the guests consented that it would be a good idea to gather all the information put forth at the meeting and have it published. In addition, although they were unfortunately unable to attend the symposium . many other distinguished scientists had also expressed their wish to contribute to this effort and, in so doing. help to increase understanding in this, as yet, relatively immature field of science . The question of both positive and negative effects of magnetic and electromagnetic fields on biological systems has become more and more important in our world today as they .
Download and read online Mechanistic Approaches to Interactions of Electric and Electromagnetic Fields with Living Systems in PDF and EPUB Although there is general agreement that exogenous electric and electromagnetic fields influence and modulate the properties of biological systems. there is no concensus regarding the mechanisms by which such fields operate. It is the purpose of this volume to bring together and examine critically the mechanistic models and concepts that have been proposed. We have chosen to arrange the papers in terms of the level of biological organization emphasized by the contributors. Some papers overlap categories. but the progression from ions and membrane surfaces. through macromolecules and the membrane matrix to integrated systems. establishes a mechanistic chain of causality that links the basic interactions in the relatively well understood simple systems to the complex living systems. where all effects occur simultaneously. The backgrounds of the invited contributors include biochemistry. biophysics. cell biology. electrical engineering. electrochemistry. electrophysiology. medicine and physical chemistry. As a result of this diversity. the mechanistic models reflect the differing approaches used by these disciplines to explain the same phenomena. Areas of agreement define the common ground. while the areas of divergence provide opportunities for refining our ideas through further experimentation. To facilitate the interaction between the different points of view, the authors have clearly indicated those published observations that they are trying to explain. i.e. the experiments that have been critical in their thinking. This should establish a concensus regarding important observations. In the discussion of theories.

As such, it must cover the possible reproducible mechanisms of action/reaction EMF-Biological Organism, the appropriate models that allow quantitative measurements, the basic biological reproducible effects and possible therapeutic effects along with their prevalent metrics and international exposure criteria. This is exactly the main objective of this book. It is also believed that it provides some new results and conclusions which complement, clarify and verify the existing results in the literature included in the references  and . Electromagnetic Radiation is a form of energy, which is transmitted in the form of waves which correspond to spatial and time variations of the electric and magnetic field. Electromagnetic fields appear in a vast set of frequencies (spectra) that are divided in frequency zones, according to the manner they are produced or used. Areas greater than 300 gigacycles (GHz), which include the solar spectrum, as well as x and gamma rays, have been studied sufficiently under a different angle in relation to possible biological effects. People are well aware of the harmful effects of sun radiation when they are exposed to the sunlight for extended periods of time and of the catastrophic effects of nuclear bombs and nuclear reactor leaks.
