A Study of the Biological Effects of Certain ELF Electromagnetic Fields

A. P. Krueger, E. J. Reed · 1975

Researchers exposed young mice to simulated ELF electromagnetic fields at 45 Hz and 75 Hz at 100 V/m and measured growth rate, serotonin metabolism, and susceptibility to influenza virus. No significant difference in growth rate was found between exposed and control mice across experiments lasting 12 to 26 days. Four separate influenza challenge tests at 75 Hz and 100 V/m found no evidence of altered resistance using cumulative mortality rates and LD50 titers.

Conditions of Strongest Electromagnetic Power Deposition in Man and Animals

Gandhi OP · 1975

The strongest whole-body absorption occurred when the electric field was polarized along the body's longest dimension at frequencies where the body length was about 0.4 times the free-space wavelength. When a ground plane was present, peak absorption shifted to frequencies about one-half as high as for bodies isolated in free space. At resonance, an effective absorption area of 3=4 times the shadow cross-section was measured. Maximum power deposition was found in the neck region, with an absorption coefficient about 20 times the whole-body average under both free-space and parallel-plate waveguide conditions.

Investigation of Electrical Impedance Variations of Dog Brain Tissue During Experimental Metabolic Disturbances

J. LENOIR, C. ROULLET, P. JENIN, A. L. THOMASSET, M. PELLET · 1975

Normal tissue showed about 800 ohms at 5 kHz and 400 ohms at 1 MHz with a stable ratio. Controlled hemorrhage caused impedance to surge when arterial pressure fell below 25–30 mmHg, and recovery failed even after blood transfusion restored pressure. Carbon monoxide inhalation repeatedly raised impedance, with each recovery taking longer than the last.

THE DETECTION OF RF DAMAGE TO HIGH MOLECULAR WEIGHT BIOPOLYMERS BY RAMAN SPECTROSCOPY

Charles A. Cody et al. · 1975

Researchers used a custom Raman spectrometer assembled by Block Engineering personnel to obtain Raman spectra. Infrared spectra were recorded on a Digilab FTS-15 Fourier transform spectrophotometer. The program established that biological materials do damage when exposed to RF radiation and that molecular spectroscopy methods yield data needed to generate RF radiation hazard parameters. Raman spectroscopy encountered fluorescence and sensitivity problems, while infrared techniques appeared satisfactory from preliminary data but the effect of water-rich background matrices and the ability to do micro-damage assessment were not completely known.

Some Considerations Concerning the Use of Magnetron Generators in Microwave Biological Research

Vernon R. Reno · 1975

Measurement instruments with different response times gave different readings of the same magnetron field, with a slow-response sensor averaging out the variations. The magnetron waveform and pulse energy distribution changed with average power level and showed variability between pulses at lower power levels. Spectral analysis revealed the magnetron energy was distributed in multiple narrow bands around 2450 MHz, with more bands appearing at higher power levels.

Exposure of Rabbit Erythrocytes to Microwave Radiation

P. E. Hamrick, J. G. Zinkl · 1975

Researchers exposed rabbit erythrocytes to 2450 and 3000 MHz microwave radiation at multiple intensities to test for changes in potassium efflux and osmotic resistance. No significant differences were found between exposed and control cells in potassium efflux, osmotic resistance, or hemoglobin efflux.
