Electromagnetic Fields (300 Hz to 300 Ghz) (Paperback)

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 radiofre-quency 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.
