It has been known all along that RF/MW radiation excites the water molecules in human tissue and causes heating, and most attempts at setting safety standards have been based solely on that aspect. But the nonthermal effects are the more important and biologically fascinating ones. In humans, EMFs in various frequencies have been found to adversely affect calcium binding at the cell surface, DNA synthesis, and cell division; to alter circadian rhythms, affect or alter some important enzyme activities, and affect specific glands like the pineal and the hypothalamus area of the brain as well as the production of certain neurotransmitters, like seratonin and dopamine production; to increase the permeability of the blood-brain
