The only people who have declared mobile phone masts safe are the mobile phone industry and their loyal supporters. There are hundreds of peer reviewed published studies that demonstrate how radiation from wifi, mobile phones, masts etc causes ill health and cancer. The mobile phone industry would have us believe that all the studies that show these hundreds of positive results did not exist or were somehow irrelevant while all the studies (mostly funded by the mobile phone industry) that show negative results were the only ones worth noting. But this is exactly what the asbestos and tobacco industries did in the last century to safeguard their profits at the expense of a percentage of the population.
