MICROWAVE IRRADIATION SACRIFICE – APPLICATION IN NEUROCHEMICAL RESEARCH

D.E. Schmidt, M.J. Schmidt, G.A. Robison · 1973

Researchers applied microwave irradiation sacrifice to rats and measured brain temperature, enzyme inactivation rates, and levels of acetylcholine and cyclic AMP. Brain temperature reached 70-80°C within 15-20 seconds of microwave exposure. Complete and simultaneous inactivation of cholinesterase, phosphodiesterase, and adenyl cyclase occurred throughout the brain at temperatures of 60-75°C. Acetylcholine levels were higher than literature values, free choline was significantly lower at 28.7 nmoles/mg whole brain, and cyclic AMP levels were comparable to those from rapid freezing.

PROBLEM OF EVALUATION OF EEG FINDING IN RELATION TO THE GRADE OF EXPOSURE TO USW RADIOWAVES

Styblova V., Holovska V., Spondova V., Zubrik L. · 1973

The mean daily irradiation value was 30.7 with a range of 6.5 to 97.1, and the measurement error was stated as + 30%. No significant differences in EEG findings were found between the exposed group and the control group. A significant coincidence was found between headache incidence and EEG abnormality percentage, particularly for migraine. The authors concluded that electromagnetic energy at the exposure dose did not damage the central nervous system and that EEG abnormalities should be assessed in relation to migraine incidence.

Retinal Damage Thresholds for Multiple Pulse Lasers

Robert W. Ebbers, Irving L. Dunsky · 1973

Researchers used a Q-switched neodymium laser at 1.06 µm to determine retinal damage thresholds in 100 rhesus monkey eyes. Each eye was exposed to five pulse configurations: single pulse, 10 pps for 0.5 sec, 10 pps for 1 sec, 20 pps for 0.5 sec, and 20 pps for 1 sec. Probit analysis showed no significant difference between the single-pulse ED-50 and the peak-pulse ED-50s in any pulse train. For average pulse energy, the 20 pps 0.5 sec and 20 pps 1 sec ED-50s were significantly lower than the single-pulse ED-50.

Caloric Vestibular Stimulation via UHF-Microwave Irradiation

Robert M. Lebovitz · 1973

The paper proposes that absorbed microwave radiation creates thermal gradients in the semicircular canals, producing convective torque that mimics natural vestibular simulation. The analysis derives a detection threshold of 35 mW/cm², which may be significantly lower when resonance absorption occurs in small heads. Nystagmus onset is predicted at incident power densities between 100 and 400 mW/cm² depending on intracranial absorption patterns.
