Everyone, whether they like it or not, is exposed to electromagnetic fields, most of the time, at very low levels. In this case, they are inconsequential, but they can cause adverse health effects when they become intense enough. This topic is complex and sensitive. Covering frequencies from 0 Hz to 300 GHz, Human Exposure to Electromagnetic Fields provides an overview of this vast topic. After a reminder of the concepts of electromagnetic fields, the author presents some examples of sources of radiation in daily life and in the industrial or medical sectors. The biophysical and biological effects of these fields on the human body are detailed and the exposure limits are recalled. The exposure assessment and the implementation of the appropriate regulation within companies are also covered. Technically and practically, this book is aimed at people with a scientific background, risk prevention actors, health physicians, especially occupational doctors, and equipment designers.

A critical review of all data relevant to the assessment of human health effects associated with exposure to electromagnetic fields in the frequency range of 300 Hz to 300 GHz. Emphasis is placed on new data that shed light on the interactions of electromagnetic fields with biological systems and on the specific biological effects and responses that result. Over 500 recent studies were rigorously assessed. Sources of exposure considered include broadcasting systems, microwave ovens, induction heating stoves, visual display units, television receivers, dielectric heaters for industrial use, radar installations, and medical devices and procedures. A chapter devoted to interaction mechanisms reviews the electrical properties of tissues and discusses direct and indirect interaction mechanisms, including the interaction of biological bodies with electrical charges induced on ungrounded or poorly grounded metallic objects such as cars, cranes, wires and fences. A review of the large body of data from cellular and animal studies considers the strength of evidence pointing to effects on the nervous, endocrine, and immune systems, on reproduction and on pre- and post-natal development. The report concludes that most of the biological effects of acute exposure are consistent with responses to induced heating. Data on human responses are assessed in the next chapter which addresses concern about the effects of locally elevated temperatures resulting from the deposition of radio frequency energy and the possible dangers, particularly for pregnancy outcome linked to the use of visual display units. The report concludes that current data provide no clear evidence of detrimental health effects in humans exposed to radiofrequency fields. The remaining chapters provide guidelines for health hazard assessment and standards for protection.

The possible health effects of electro-magnetic (EMF) from high-voltage electric power lines have been discussed sine the 1970s. The concern was triggered by epidemilogical studies in the United States and Europe that suggested a slightly increased incidence of leukaemia's and brain tumours occured among those living and working near high-voltage power lines. Although studies can indicate an associate between factor and effect, the studies themselves cannot confirm a cause-effect relationship. Whether EMF is producing these ill effects must be confirmed by experimental studies.
