Effects of 27 MHz Radiation on Somatic and Germ Cells.
Department of Physiology, Medical College of Virginia, Virginia Commonwealth University 1991 Jan:8 pages
A study was made of the dose dependence of effects of 27 and 2450 megahertz (MHz) continuous wave (CW) and pulse modulated (PM) radiation exposure of normal resting peripheral human lymphocytes, human glioma (LN71), HeLa, and Chinese-hamster-ovary (CHO) cells. Direct radiation effects on mouse germ cells were also investigated. Effects of high frequency electromagnetic radiation (EMR) on lymphocyte and glioma mitogenesis and the CHO cell cycle in-vitro provide evidence of direct dose or dose rate dependent alteration of a highly physiologically significant cellular endpoint. Although in- vitro data cannot be extrapolated directly to in-vivo responses, the experimental conditions of these in-vitro studies suggest that qualitatively similar effects may be induced by in-vivo exposure to electromagnetic fields of these frequencies. The author concludes that physiologically significant cellular alterations are induced by 27 and 2450MHz CW and PM radiation exposure under conditions that do not involve heating. The author suggests that the adequacy of radiofrequency occupational exposure guidelines that suggest that health effects are attributable to radiation induced tissue heating must be questioned.
