Alkaline phosphatase activity in neutrophils rose significantly in the first week of irradiation and fell transiently after irradiation ceased. In the post-irradiation interval, exposed rats displayed a significant decline in rate of body weight increase.

Researchers tested three inexpensive microwave survey instruments—the Micromate, Guard-Rod, and Interceptor/Microscan—and evaluated several test parameters. Cross-polarized fields increased the Micromate’s sensitivity by 216 % and the Guard-Rod’s by up to 694 %; amplitude-modulated fields increased the Micromate’s sensitivity by 119 % and decreased the Guard-Rod’s by up to 64.5 %; the Interceptor/Microscan responded to peak power, increasing sensitivity fivefold.

The study tested whether millimeter microwaves affect the function of alcohol dehydrogenase and hemoglobin in vitro. Alcohol dehydrogenase was exposed to 40–115 GHz radiation at near 10 mW/cm² while monitoring the reaction rate via NADH absorption using a 337 nm filter. No change in alcohol dehydrogenase turnover rate was detected within a sensitivity of 0.1%. Hemoglobin at half-oxygenation was exposed to absorbed intensity of 3–13 mW/cm² across 40–115 GHz. No shift in the equilibrium oxygen constant of half-oxygenated hemoglobin was detected within a sensitivity of 0.4%.

Laboratory studies have shown that electromagnetic fields similar to those from high-voltage transmission lines can produce biological effects. Correlation has been established between the presence of transmission-line fields and the occurrence of suicides in part of the Midlands of England.

An excess of electrical wiring configurations suggestive of high current flow was noted near the homes of children who developed cancer compared to control children in Colorado during 1976-1977. The association was strongest for children who had lived their entire lives at the same address and appeared to be dose-related. The correlation did not appear to be explained by neighborhood, street congestion, social class, or family structure.

Instruments should read average power density, mean squared electric field strength, mean squared magnetic field strength, or energy density. Calibration methods include free-space standard field, guided wave methods, and standard probe method.

Human exposures up to 20,000 G produced only transient sensations such as a metallic taste or tooth pain in individuals with dental fillings, while Soviet magnet-fabrication workers reported cardiovascular and neurological symptoms at unspecified field strengths. In rabbits, stationary fields of 200–1000 G for 1–3 minutes altered EEG patterns, with a threshold around 100 G, and long-term exposure caused neuroglial and neuronal lesions. Mice exposed to 4200–9000 G showed a significant decrease in bone-marrow megakaryocytes and a statistically significant increase in splenic megakaryocytes.

Researchers studied the circumesophageal connective of the lobster to investigate the influence of a constant magnetic field on nerve impulse conduction velocity. They found no significant effect of a 1.2 T magnetic field on conduction velocity in either parallel or perpendicular configurations.

Each trial asked the subject to decide whether a 60 Hz magnetic field of 7.5–15 gauss was present, with the field randomized by computer. After more than 30,000 total trials, no individual performed better than chance, and group results were consistent with no real perception.

The method places a liquid sample in one arm of a Mach-Zender interferometer illuminated by a helium-neon laser and irradiates it with pulsed microwaves. Microwave absorption causes local thermal expansion that creates phase fluctuations in the laser beam, which are detected by heterodyning with a reference beam. The researchers plan to evaluate water, ethanediol, and other biologically significant liquids using a coaxial stub antenna and a miniature dielectric-loaded X-band waveguide. The technique offers very high sensitivity for detecting small temperature rises and produces no signal when there is no absorption.
Ohno, K., Pettigrew, K.D., Rapoport, S.I. · 1978
They measured cerebrovascular permeability-area products for 14C-sucrose in 5 brain regions. Mean PA values were similar across sham, 1 mW /cm², and 10 mW/cm² groups. The authors concluded that an effect of microwave treatment on barrier permeability cannot be concluded.
