William Haddon Jr., ., IIHS president from 1969 to 1985, is widely considered the father of modern injury epidemiology. He argued for a more scientifically driven approach to injury control and created conceptual frameworks, such as the Haddon Matrix, for understanding how injuries occur and developing strategies for intervention. His pioneering efforts helped transform the highway safety field from one focused solely on crash prevention to one that examines human, vehicle and environmental factors to identify a full range of options for reducing crash losses.
It is important to remember that the strength of a magnetic field decreases dramatically with increasing distance from the source. This means that the strength of the field reaching a house or structure will be significantly weaker than it was at its point of origin, as you can see below. For more information, see the NIEHS educational booklet, “ EMF: Electric and Magnetic Fields Associated with the Use of Electric Power. ”. This booklet, prepared in 2002, contains the most recent NIEHS research on health and powerline electric and magnetic fields. The World Health Organization website has information prepared in 2010. For example, a magnetic field measuring milligauss immediately beside a 230 kilovolt transmission line measures just milligauss at a distance of 100 feet, and milligauss at a distance of 200 feet.
