Health aspects of radio-frequency radiation accidents. Part I: Assessment of health after a radio-frequency radiation accident

Unknown authors · 1988

Nine men were exposed to 4.1 GHz radio-frequency radiation in an accident. Two men were exposed to 4.6 mW/cm2 for up to 90 minutes, exceeding the Australian standard of 1 mW/cm2, while seven others received lower exposures. Comprehensive medical examinations, including follow-up ophthalmological exams over nine months, were performed on all staff. Various abnormalities were found in all staff, but there was no consistent gradient of effect between exposure groups except possibly for hair loss. The investigators concluded that the exposure had not resulted in harmful effects.

Microwave effects on plasmid DNA

Unknown authors · 1987

Purified plasmid DNA was exposed to microwave radiation at nonthermal levels in the frequency range from 2.00 to 8.75 GHz. The exposure produced single- and double-strand breaks detected by agarose gel electrophoresis. Microwave-induced DNA damage depended on the presence of small amounts of copper. The effect was dependent on both microwave power and exposure duration. Cuprous ions, but not cupric ions, mimicked the microwave effects on DNA.

Federal Radiation Protection Guidance; Proposed Alternatives for Controlling Public Exposure to Radiofrequency Radiation; Notice of Proposed Recommendations

Unknown authors · 1986

The EPA proposed four alternative approaches to limit public exposure to radiofrequency radiation. Three options are regulatory and would set whole-body average SAR limits of 0.04, 0.08, and 0.4 W/kg for frequencies above 3 MHz. For frequencies below 3 MHz, the regulatory options would limit electric field intensity to 87, 275, and 614 V/m and magnetic field intensity to 0.23, 0.73, and -1.63 A/m respectively. The fourth option is nonregulatory and would use information and technical assistance programs instead of adopting Federal Guidance.

WEST GERMANY PUBLISHES EMF EXPOSURE STANDARD

Thomas C. Rozzell · 1984

The article reports that West Germany published its first official human-exposure guidelines for electromagnetic fields, applicable to both workers and the general public. The German standard covers frequencies from 0.01 MHz to 3900 GHz, which is wider than the ANSI standard’s 0.1 MHz to 100 GHz range.

Environmental Health Criteria 16: Radiofrequency and Microwaves

Sol M. Michaelson · 1982

The review evaluates the World Health Organization's Environmental Health Criteria 16 document on radiofrequency and microwave fields from 100 kHz to 300 GHz. The reviewer finds the publication unbalanced because it accepts nonthermal interaction literature with cursory critique while neglecting refuting evidence. The review notes that the document's designations of high, medium, and low power densities are ambiguous and ignore the frequency dependence of bioeffects. It points out specific errors in Table 10 frequency designations and an incomplete discussion of chronic cataract studies that omitted rabbit and monkey data showing no ocular damage. The reviewer concludes the document does not meet the high scientific caliber and accuracy of usual WHO publications.

ABSTRACTS - 4th Annual Scientific Session BIOELECTROMAGNETICS SOCIETY

Unknown authors · 1982

The study induced posterior subcapsular cataracts in rabbit eyes using 2.45 GHz continuous wave radiation. Successive stages of cataract development were documented with color stereophotographs taken using a Donaldson stereo-ophthalmic camera with electronic flash illumination and two and one half times initial magnification on film. The photographs were viewed in a Donaldson special viewing apparatus that allowed consecutive stages to be seen by turning a circular knob. The viewed eye appeared as if seen in the living animal through a magnifying lens.

Radio-Frequency and Microwave Radiation

Howard Bassen · 1980

This 1980 FDA research by H. Bassen examined radio-frequency and microwave radiation exposure measurement and safety standards. The study focused on how these electromagnetic fields are absorbed by human tissue and established methods for assessing exposure levels. This represents early foundational work in understanding RF/microwave radiation effects on human health.

A Study To Investigate Federal Regulation of Microwave Standards

Leonard David · 1980

The study outlines the historical background of U.S. microwave exposure guidelines and identifies the lead federal agencies. No federal standards exist to protect workers or the public, only a voluntary 10 mW/cm² guideline from 1966. Regulatory trends point toward more stringent occupational and public exposure limits, possibly as low as 1 mW/cm². The SPS system would deliver 23 mW/cm² at the rectenna center, 1 mW/cm² or less at the edge, and 0.1 mW/cm² at the buffer zone boundary. Current data show no morbid effects from 2,450-MHz radiation below 1 mW/cm², but long-term exposure studies are lacking.
