Research on Biological Effects of VLF Band Electromagnetic Radiation.
Abstract
The investigation was undertaken to determine whether exposure of mice to very high field intensities of very-low-frequency-(VLF-) electromagnetic radiation will produce nonthermal-detrimental biological effects. Two field intensities were employed at a frequency of 25 kHz: E = 15,000 V/m and H = 7.5 A/m for full-power exposures, and E = 10,600 V/m, H = 5.3 A/m for one-half-power exposures. The 15,000 V/m electric field and the 7.5 A/m magnetic fields were equal to a power 59,500 mW/sq cm and 2,120 mW/sq cm or 5,950 and 212 times greater, respectively, than the 10 mW/sq cm current US standard.. Growth, reproduction, metabolism, and pathological studies of VLF effects were conducted on C3H/He mice exposed to both the one-half-power and full-power fields. Exposure consisted of 1 hr per day, 5 days a week. The results indicated that the high-intensity low-frequency electromagnetic radiation exposure of dams and neonates had no statistical detectable effect on the growth, reproductive ability, and metabolism of the neonates or the growth of their subsequent offspring.
