Municipal Wi-Fi in Britain doesn't seem to be hitting the same stumbling blocks that it's American counterpart. With millions of subscribers and entire cities going Wi-Fi, Britain has developed a new concern... health risks.
The radiation produced from a Wi-Fi tower is similar to that from a cell phone tower. And in 2000 Sir William Stewart, current Chairman of the Health Protection Agency, led a study into the effects of cell phone tower radiation and determined that there was enough reason to be concerned and suggested a precautionary approach to putting towers near schools. Radiation levels are much lower than the safety limits in Britain but with entire schools going Wi-Fi there is an increased radiation level. Currently, there are studies being performed across the world and the jury is still out on this possible health problem.
