Abstract
Several studies have demonstrated detrimental effects of cellular phone radiation on in-vitro biological systems. This article introduces a novel in-vitro method for demonstrating conformational changes in human DNA induced by a 5 minute exposure to cellular phone radiation emitted by an actual contemporary cellular phone. Dynamic changes in DNA conformation was determined in real-time by measuring the rate of DNA rewinding (in a spectrophotometer) following exposure to heat which causes the unwinding of the two strands of the helix. Cellular phone radiation produced a 40% increase in the rate of DNA rewinding. This effect was 95% attenuated when the experiment was repeated with the same cellular phone to which was attached a commercially available shielding disk shaped sheet containing a paramagnetic mineral. In a separate series of experiments the intensity of the cellular phone radiation was measured using an electromagnetic frequency spectrum analyzer. The intensity was reduced by approximately 50% in the presence of the shielding disk. Taken together these studies indicate the efficacy of a shielding disk to protect the body from cellular phone radiation.
