Radiofrequency Radiation Standards


Book Description

The North Atlantic Treaty Organization (NATO) has sponsored research and personnel safety standards development for exposure to Radiofrequency Radiation (RFR) for over twenty years. The Aerospace Medical Panel of the Advisory Group For Aerospace Research and Development (AGARD) sponsored Lecture Series No. 78 Radiation Hazards,! in 1975, in the Netherlands, Germany, and Norway, on the subject of Radiation Hazards to provide a review and critical analysis of the available information and concepts. In the same year, Research Study Group 2 on Protection of Personnel Against Non-Ionizing Electromagnetic Radiation (Panel VIIl of AC/243 Defence Research Group, NATO) proposed a revision to Standardization Agreement (STANAG) 2345. The intent of the proposal was to revise the ST ANAG to incorporate frequency-dependent-RFR safety guidelines. These changes are documented in the NATO STANAG 2345 (MED), Control and Recording of Personnel Exposure to Radiofrequency Radiation,2 promulgated in 1979. Research Study Group 2 (RSG2) of NATO Defense Research Group Panel VIII (AC1243) was organized, in 1981, to study and contribute technical information concerning the protection of military personnel from the effects of radiofrequency electromagnetic radiation. A workshop at the Royal Air Force Institute of Aviation Medicine, Royal Aircraft Establishment, Farnborough, U. K. was held to develop and/or compile sufficient knowledge on the long-term effects of pulsed RFR to maintain safe procedures and to minimize unnecessary operational constraints.

Non-ionizing Radiation Protection


Book Description

A comprehensive review of non-ionizing radiation and its public health and environmental risks, for researchers, policy makers, and laymen This book explains the characteristics of all forms of electromagnetic non-ionizing radiation (NIR) and analyzes the relationship between exposure and its biological effects, as well as the known dose-response relationships associated with each. Taking a uniquely holistic approach to the concept of health that builds upon the WHO definition to include not only absence of disease, but the physical, mental and social well-being of individuals and the population, it reviews established and potential risks and protections, along with regulatory issues associated with each. The risks to public health of NIR, whether in the form of UV light, radio waves from wireless devices, or electric and magnetic fields associated with electrical power systems, is currently a cause of great concern among members of the public and lawmakers. But in order to separate established science from speculation and make informed decisions about how to mitigate the risks of NIR and allocate precious resources, policymakers, manufacturers, and individuals need a comprehensive source of up-to-date information based on the current scientific evidence. Written by a team of experts in their fields, this book is that source. Among other things, it: Summarizes scientific findings on the safety of different forms of NIR and the rationale behind current standards Describes devices for monitoring NIR along with the established and potential hazards of each form Explores proper protections against UV light and lasers, RF radiation, ELF fields and other forms of NIR Discusses how to avoid injuries through occupational training or public awareness programs, and how to perform medical assessments in cases of suspected NIR injuries Considers how to decide whether or not to spend money on certain mitigation measures, based on cost-benefit analyses Offering expert reviews and analyses of the latest scientific findings and public policy issues concerning the risks to public health and the environment of NIR, Non-ionizing Radiation Protection is an indispensable source of information for manufacturers, government regulators, and regulatory agencies, as well as researchers, concerned laypersons, and students.







Electromagnetic Fields (300 Hz to 300 GHz)


Book Description

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.




Radio Frequency Radiation Dosimetry and Its Relationship to the Biological Effects of Electromagnetic Fields


Book Description

The North Atlantic Treaty Organization (NATO) has sponsored research supporting development of personnel safety standards for exposure to Radio Frequency Radiation (RFR) for over a quarter century. NATO previously recognized that one of the most important tools used in the RFR effects research laboratory is accurate dosimetry when it supported a NATO Advanced Studies Institute (ASI) on Advances in Biological Effects and Dosimetry of Low Energy Electromagnetic Fields held in 1981, in Erice, Sicily. That meeting resulted in a NATO ASI publication; Biological Effects and Dosimetry of l Non-ionizing Radiation: Radiofrequency and Microwave Energies . The most recent NATO sponsored program on RFR was an Advanced Research Workshop (ARW) on "Developing a New Standardization Agreement (STANAG) for Radio frequency Radiation" held May 1993, at the Pratica di Mare Italian Air Force Base, Pomezia (Rome) Italy. That ARW produced an ASI proceedings, published in 1995: Radio frequency Radiation Standards, Biological Effects, Dosimetry, Epidemiology, and Public Health Policy2. The Rome ARW and the Proceedings served as a springboard to the much needed revision of the NATO Standardization Agreement (STANAG) 2345 MED "Evaluation and Control of Personnel Exposure to Radio Frequency Fields - 3 kHz to 300 GHz,,3, which was subsequently promulgated in October 1998. One of the published recommendations developed by the Rome ARW was to hold this second ARW focusing on dosimetry and measurements.
