Electromagnetic Radiation and the Internal Organs

The thyroid gland is one of the most sensitive indicators of microwave influence. Animal experiments show increased activity and/or enlargement of the thyroid at 153 μW / cm2 (Demokidova, 1973) [1], at 100 μW / cm2 (Gabovich et al., 1979; [2] Navakatikian and Tomashevskaya, 1994 [3]), and at 1 μW / cm2 (Dumansky and Shandala, 1973 [4]). Several clinical studies confirm this (Drogichina, 1960 [5]; Sadchikova, 1960 [6]; Smirnova and Sadchikova, 1960 [7]; Baranski and Czerski, 1976 [8]). Smirnova and Sadchikova (1960) [7] states that physiological and even pathological changes in the activity of the thyroid can be detected long before any clinical manifestations of microwave injury. In this study 35 out of 50 persons working with microwave equipment showed abnormal thyroid activity. Drogichina (1960) [5] reports increased thyroid activity in almost all microwave workers examined.

The adrenals are also extremely sensitive to radiation. In animals irradiated for from 2 months up to 2 years, the adrenals are generally enlarged, have an altered ascorbic acid content, increase the secretion of adrenaline and glucocorticoids, and decrease the secretion of testosterone: Chou and Guy at 500 μW / cm2 (Lerner, 1984) [9], Navakatikian and Tomashevskaya (1994) [3] at 100 μW / cm2, Gabovich et al. (1979) [2] at 100 μW / cm2, Dumansky et al. (1982) [10] at 25 μW / cm2, Shutenko et al. (1981) [11] at 10 μW/cm2, Dumansky and Shandala (1973) [4] at 0.06 μW / cm2. With a shorter exposure, Giarola et al. (1971) [12] found a decrease in the mass of the adrenals in chickens at 14-24 μW / cm2. In clinical studies, Sadchikova (1973) [13] noted altered excretion of epinephrine and norepinephrine; Kolesnik et al. noted a decreased blood 17-CHS response to ACTH injection in all 35 workers tested (Baranski and Czerski, 1976 [8]); Hasik, and also Presman, noted increased activity of the adrenal cortex (Dodge, 1969). [14]

Ray and Behari (1990) found a significant decrease in the weight of the spleen, kidney, brain and ovary, and an increase in testicular weight in young rats exposed to 7.5 GHz, 600 μW /cm2, 3 hours a day for 60 days. [15]

Dumansky and Shandala (1973) [4] found increased RNA and DNA in the liver and spleen, and structural changes in the liver, spleen, testes, and brain of white rats and rabbits exposed to 3 cm and 12 cm waves at 0.06 to 101μW / cm2 for 8 to 12 hours a day for 180 days.

Giarola et al. (1971 [12], 1973 [16]) report an enlarged spleen and thymus in baby rats exposed for 35-53 days to 880 MHz, 14 μW / cm2.

Erin’ (1979) [17] reports a 23-83% increase in oxygen tension in renal tissues of adult white rats exposed to 2375 MHz, 50 μW / cm2 for 1-10 days.

Belokrinitsky (1982) [18] observed changes in the biochemistry and ultrastructure of liver, heart, kidney and brain tissue in rats exposed to 12.6 cm waves at intensifies of 5 μW / cm2 and higher for up to 2 months.

50 W / cm2 for 7 hours a day for 10 days caused urine output to fall 15%, and 500 μW / cm2 once for 7 hours had a larger effect (Belokrinitsky and Grin’, 1982 [22]). Elevation of urine pH, protein in the urine, and changes in electrolyte excretion persisted up to 25 days after exposure. Examination of kidney tissue revealed vasodilation, endothelial breakdown, perivascular and pericellular infiltrations, hemorrhage, swelling, partial de-epithelialization along the nephron, and other changes. Histochemical analysis showed decreased cellular glycogen, changes in RNA and DNA concentration, and the appearance of neutral fat droplets. Some of these changes were irreversible, even two months after one 7-hour exposure.

In large clinical studies, Orlova (1960) [19] noted decreased appetite, indigestion, epigastric pain, and enlargement of the liver in irradiated workers, while Gel’fon and Sadchikova (1960) [6] also noted liver enlargement and tenderness in certain patients, with a decreased antitoxic function of the liver in a few. Trinos (1982) [20] noted decreased appetite and indigestion, as well as chronic gastritis, cholecystitis, and decreased gastric acidity, especially in workers exposed to microwaves for more than ten years. Bachurin (1979) [21] also noted chronic gastritis and cholecystitis in workers occupationally exposed to 20-100 μW / cm2.
