Triyambakam, please don't take these criticisms much to heart. Smokers were parroting the tobacco industries claims that smoking didn't cause cancer in their own ignorance. There may be a similar thing happening now with the wireless industry. We are just scientifically beginning to discover the non-thermal effects of EMF radiation. If these fields do cause detectable changes to the pysiology of human cells, there is reason to believe that your wife could be sensitive to these changes.
