Descriere & specificații

A link between power line magnetic fields and childhood leukemia was revealed in a 1979 health study. More studies in the U.S. and Europe supported these findings, including links to other diseases. But when careful measurements were made in schools, offices and residences it was found that most high magnetic fields in buildings were caused by certain common wiring errors, as well as by electric currents on water pipes due to grounding practices. Karl Riley pioneered a successful method of tracing high magnetic fields to the site of the error. A simple correction clears the field. Though his clients in 17 states may see him as an electrical Sherlock Holmes, he follows a simple, logical measurement sequence which leads him inevitably to the spot where the error was made. Correction is simple and obvious. His entire diagnostic method is spelled out in this book, for the use of electricians or technically inclined home owners. About the Author: Karl Riley's breakthrough discoveries as to the causes of high magnetic fields in buildings were helped by his not being either an electrician or an electrical engineer. A fresh viewpoint was needed. He had just retired from science teaching on Marthas Vineyard (MA, Columbia T.C.) when a neighbor asked for help when her guests were getting electric shocks from her outdoor shower. His investigation, using a simple voltmeter, showed the utility company where to dig. They uncovered a sliced hot conductor, cut earlier by a plumber's back hoe.
