![]() ![]() The debate about cell phones and brain cancer still rages today, particularly for the microwave frequencies encountered with new 5G technology. Along the way, the author looks in depth at the dispute about power line magnetic fields and leukemia, a case study in what can go wrong when dubious claims inflame unjustified fears. ![]() This book takes the reader on a tour through a range of fascinating phenomena, from effects that are constant in time at one extreme, such as transcranial direct current stimulation of the brain, to the millimeter-wave whole-body scanners which are familiar to frequent flyers at the other. In this book, the author separates the wheat from the chaff, showing which applications of E&M are bogus and which are not. ![]() How do you separate the good from the bad? Sometimes it’s not easy: experiments are prone to artifacts, theories are limited by assumptions, and clinical trials can result in ambiguities. But E&M also attracts its share of bogus health claims, such as biomagnetic therapy. Electricity and Magnetism (E&M) underlies many lifesaving medical devices, such as magnetic resonance imaging scanners, neural stimulators, and heart pacemakers. ![]()
