Can the electric and magnetic fields (EMF) to which people are routinely exposed cause health effects? This volume assesses the data and draws conclusions about the consequences of human exposure to EMF. The committee examines what is known about three kinds of health effects associated with EMF: cancer, primarily childhood leukemia; reproduction and development; and neurobiological effects. This book provides a detailed discussion of hazard identification, dose-response assessment, exposure assessment, and risk characterization for each. Possible Health Effects of Exposure to Residential Electric and Magnetic Fields also discusses the tools available to measure exposure, common types of exposures, and what is known about the effects of exposure. The committee looks at correlations between EMF exposure and carcinogenesis, mutagenesis, neurobehavioral effects, reproductive and developmental effects, effects on melatonin and other neurochemicals, and effects on bone healing and stimulated cell growth.

This report was prepared by the Office of Technology Assessment of the United States Congress to review the health effects of high-voltage transmission lines. For about two decades, there has been some concern about the health effects of electric and magnetic fields produced by transmission lines. Recent studies have heightened this concern. Health effects research is still preliminary and inconclusive, but a growing number of studies suggest that under certain circumstances even relatively weak electric and magnetic fields can produce biologic changes.This report discusses the present state of knowledge on the health effects of low-frequency electric and magnetic fields and describes current U. S. funding levels and research programs. Also, the report provides information on regulatory activity, including existing and proposed field exposure standards.

William Leiss and Christina Chociolko explain that controversies arise in part because many participants try to avoid assuming full responsibility for the consequences of the risk-taking they advocate. For example, one can indulge in the pleasure of nicotine addiction despite an awareness of the health risks and count on a publicly funded health care system to assume the responsibility for dealing with the resulting illnesses. They provide detailed case studies of the controversies over the effects of exposure to power frequency electric and magnetic fields and to the chemical pesticides alar and antisapstains. Shorter studies of exposure to tobacco, formaldehyde, and the pesticide alachlor are also presented. The authors address the difficulties of arriving at reliable scientific estimates of risk in such controversial areas, and the impact of this uncertainty on disagreements among different interest groups over how to manage those risks responsibly. In conclusion they attempt to delineate conditions under which consensus on the assessment and management of environmental health risks might be achieved among a wide range of interest groups. Risk and Responsibility will be of specific interest to policymakers and analysts, activists, and environmentalists, and of general interest to those working in relevant industries and members of the legal profession.

The theory of transmission lines is a classical topic of electrical engineering. Recently this topic has received renewed attention and has been a focus of considerable research. This is because the transmisson line theory has found new and important applications in the area of high-speed VLSI interconnects, while it has retained its significance in the area of power transmission. In many applications, transmission lines are connected to nonlinear circuits. For instance, interconnects of high-speed VLSI chips can be modelled as transmission lines loaded with nonlinear elements. These nonlinearities may lead to many new effects such as instability, chaos, generation of higher order harmonics, etc. The mathematical models of transmission lines with nonlinear loads consist of the linear partial differential equations describing the current and voltage dynamics along the lines together with the nonlinear boundary conditions imposed by the nonlinear loads connected to the lines. These nonlinear boundary conditions make the mathematical treatment very difficult. For this reason, the analysis of transmission lines with nonlinear loads has not been addressed adequately in the existing literature. The unique and distinct feature of the proposed book is that it will present systematic, comprehensive, and in-depth analysis of transmission lines with nonlinear loads. - A unified approach for the analysis of networks composed of distributed and lumped circuits - A simple, concise and completely general way to present the wave propagation on transmission lines, including a thorough study of the line equations in characteristic form - Frequency and time domain multiport representations of any linear transmission line - A detailed analysis of the influence on the line characterization of the frequency and space dependence of the line parameters - A rigorous study of the properties of the analytical and numerical solutions of the network equations - The associated discrete circuits and the associated resisitive circuits of transmission lines - Periodic solutions, bifurcations and chaos in transmission lines connected to noninear lumped circuits
