Depression of phagocytosis: a non-thermal effect of microwave radiation as a potential hazard to health

C. P. MAYERS, J. A. HABESHAW · 1973

Researchers exposed mouse macrophage monolayers perfused with human red blood cells to 2450 MHz microwave radiation at 50 mW/cm² for 30 minutes while maintaining temperature at 37°C. The phagocytic index fell to 6.3 ± 2.5 per cent in irradiated cultures compared with 20.2 ± 5.8 per cent in unirradiated controls, a statistically significant difference (P < 0.025). Phagocytic activity returned to normal after radiation was stopped, and no morphological changes were observed in the macrophages.

Possible Mechanisms for the Biomolecular Absorption of Microwave Radiation with Functional Implications

James R. Rabinovitz · 1973

The author performed a theoretical analysis of several possible modes of molecular absorption of microwave radiation. Absorption increases rotational energy, allowing segments to occupy different potential wells or tunnel between wells, changing the relative position of segments without altering covalent bonds. These non-covalent structural changes provide a model for direct interference with biomolecular functions that depend on internal three-dimensional structure.

Clinico-morphological and biochemical changes in experimental microwave cataracts

Grechuskina, V.A. · 1972

Cataracts developed in 23 rabbits, appearing first in the posterior lens suture and later regressing over two to three months. During cataract formation, ascorbic acid and thiol groups in the lens decreased sharply. During regression, ascorbic acid and thiol group levels returned to normal.

MORPHOLOGICAL CHANGES IN THE CELLS OF CORTIS ORGAN FOLLOWING EXPOSURE TO MICROWAVES

R. Zyss, E. Boczynski · 1972

Researchers exposed guinea pigs to microwaves of 2 mW/cm² intensity and 10 cm wavelength and examined morphological state, glycogen, and nucleic acids in Corti's organ. They observed degeneration of cytoplasm, pyknosis or swelling of nuclei, and swelling or vacuolar changes in the cytoplasm. The organ of Corti contained abundant glycogen only in outer hair cells. Microwave irradiation caused a marked decrease in that glycogen content.

Stimulation of Partial Limb Regeneration in Rats

R. O. Becker · 1972

Control animals with no device or very low current showed minimal growth, while high current caused bone destruction. The experimental device produced a current of 3-6 nA. Rats receiving this current frequently developed organized regrowth of the distal humerus with epiphyseal centers. In animals with higher growth scores, new organized skeletal muscle formed distal to the amputation line along with ingrowth of nerves and blood vessels, and the authors concluded that appropriate electrical stimulation can restore regenerative growth in mammals.

CHANGES IN ACTIVITY OF CERTAIN ENZYMES IN THE CELLS OF CORTI'S ORGAN IN GUINEA PIGS FOLLOWING LONG-TERM EXPOSURE TO MICROWAVES

E. Boczynski, R. Zyss · 1972

Researchers exposed guinea pigs to microwave radiation of 10 em wavelength and 2 mW/cm! intensity for 4 hours daily over 25 or 50 days. They measured succinyl dehydrogenase, lactic dehydrogenase, and acetylcholinesterase activity in Corti's organ cells using histochemical methods. Exposure decreased succinyl dehydrogenase and acetylcholinesterase activity while increasing lactic dehydrogenase activity, and these changes disappeared 30 days after exposure stopped.

Lethal Effects of Radiofrequency Energy on Eggs of Tenebrio molitor (Coleoptera: Tenebrionidae)

P. S. Rai, H. J. Ball, S. O. Nelson, L. E. Stetson · 1972

Researchers exposed Tenebrio molitor eggs to 39-MHz radiofrequency electric fields at electrode voltages of 2 to 4 kilovolts for 2 to 64 seconds. Percent hatch of 1- and 3-day-old eggs decreased as RF energy level increased, and 1-day-old eggs were more susceptible than 3-day-old eggs. No larvae survived from 1-day-old eggs treated at 4 kilovolts for 32 and 64 seconds, while 3-day-old eggs treated similarly showed low but higher larval survival.

Viability Studies on Ascospores and Vegetative Cells of Saccharomyces cerevisiae Exposed to Microwaves at 2450 MHz

P. C. B. Roberts · 1972

Researchers exposed Saccharomyces cerevisiae vegetative cells and ascospores to 2450 MHz microwaves using a hexane-cooled apparatus designed to separate thermal from non-thermal effects. At 40 watts without coolant flow, total loss of viability occurred after 30 seconds for vegetative cells and 40 seconds for spores, while suspension temperatures remained below 33°C.
