In March 1975 the Environmental Protection Agency requested data on health and environmental effects of extremely high voltage transmission lines. By March 1976 the agency had received over 50 responses comprising more than 6,000 pages of material. This report lists each respondent with a brief description of their submission and provides an alphabetical bibliography of the technical materials received. The submitted technical material consists mostly of published articles along with some technical memorandums and internal reports. Bibliographies supplied by respondents have not yet been compiled and readers are directed to the original submissions for those references.

The study derived a mathematical relation between the transmitted spectral density and the output spectral density for broad-bandwidth random-signal Doppler flow measurement systems operating under transit-time-limited conditions. The authors showed that random or pseudorandom Doppler systems give the same output spectrum as pulsed RF Doppler systems provided the transmitted spectral density envelopes match.

Researchers exposed 114 male and female mice of three distinct ages to 2450 MHz microwave radiation at 75 watts forward power until death. Time to death increased with age for both sexes, but the mean absorbed dose at death did not differ significantly with age or weight within the same sex.

Researchers exposed mammary tumors on mice to 2450 MHz microwaves at up to 200 watts in a free-field setup. Microwave heating alone from room temperature was marginal and produced unacceptably high thermal non-uniformities. Adding warm air to preheat tumors to body core temperature allowed hyperthermic temperatures of 40°C and 43°C with only 30 watts of microwave power. However, the maximum temperature deviation within tumors remained about 1.5°C, exceeding the desired uniformity of less than 0.25°C.

At 1000 mW/cm², rectal temperature rose from 38.1°C to 39.4°C in the first half hour and then fell to 38.8°C, while skin temperature rose to 38.6°C and then fell to 37.2°C. At 750 mW/cm², skin temperature increased 1.4°C then declined 1.5°C, and rectal temperature increased 0.4°C to an equilibrium of about 37.8°C. Continuous 6-hour exposure at 750 mW/cm² raised rectal temperature by 1.7°C and skin temperature by 2.8°C.

Researchers used thermographic measurements on scale models of humans in a VHF resonant cavity to determine power absorption characteristics for full-scale humans exposed to high-frequency electromagnetic fields. Peak power absorption densities of 5.63 W/kg were found for a human exposed to 10 mW/cm² at 31 MHz. Absorption decreased as the square of the frequency for frequencies below 31 MHz.

Most telemetry equipment operates between 10 and 1000 MHz with radiated power from a few microwatts to approximately 2 W. Hot spots in animal brains show heating potential 10 to 15 times higher than predicted by the RAC method.

The review assessed human vulnerability, protection materials, and methods for military operations, using sources up to October 1975. It examined biological effects of radiofrequency and microwave radiation up to 300,000 megahertz, including both thermal and nonthermal effects. The review noted that Communist research relied heavily on animal and in vitro studies of systems such as blood, cardiovascular, and nervous systems, and that Communist exposure standards were more stringent than Western standards.

The study describes two new food-industry applications of microwave power: roasting cocoa beans in Europe and drying egg-volk paste in Japan. Microwave roasting of cocoa beans proved highly effective and produced beans judged clearly superior to conventional methods. Microwave drying of egg-volk paste was found feasible and the product considered superior in characteristics to conventionally produced powder.

The study tested microwave drying using plaster bars placed in a waveguide. Water loss was recorded continuously via a balance and constraint gauge bridge with 0.5 g sensitivity. Tests were conducted at 2450 MHz = 50 MHz, power between 8 W and 200 W, with air at 6 m/s and 75°C, and results were compared with oven drying at 45°C.
