EPRI Electric and Magnetic Fields (EMF) ResearchElectric and magnetic fields (EMF) exist wherever electricity is present. Sources of EMF include electric power transmission lines, substations, overhead distribution lines, and underground cables. Electrical wiring and electrical equipment, such as office machines and household appliances, are other sources. EMF also occur naturally in the environment.For over 30 years, scientists worldwide have conducted hundreds of studies investigating whether EMF associated with electricity can produce biological changes or affect health; the Electric Power Research Institute (EPRI) has had an active EMF research program since its founding in 1973. EMF research has been reviewed in health risk evaluations by national and international organizations concerned with public health. Recent evaluations have concluded that exposure to magnetic fields measuring 0.3 0.4 microtesla (3 4 milligauss) or more is weakly associated with childhood leukemia risk. Other health outcomes have also been called into question, including the neurodegenerative disease amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), adult leukemia, adult brain cancer, and miscarriage. In accord with the findings of major health risk evaluations, EPRI EMF Health Assessment and RF Safety Program research places a great deal of emphasis on childhood leukemia. The research includes
EPRI is the only organization in North America funding long-term, multidisciplinary EMF research. To ensure objective results, EPRI carries out much of this research through sponsorship of independent scientists affiliated with major universities, laboratories, and consulting organizations. Research findings are published in peer-reviewed journals. In addition, an external, blue-ribbon scientific advisory committee provides guidance for the EMF program's research activities. In keeping with its mandate to conduct scientific research for the benefit of societies throughout the world, EPRI is continuing the search for answers to questions about EMF and health. |
