Did you know that being anywhere near the source of the emitters on a cell tower will cause your fillings in you teeth to heat up within a minute or two? We are talking about being up on the tower itself. Logical to assume that radiation propagation over distance has much the same effect over a much longer time period say, the length of the school day. The body will be exposed to some increased levels of radiated energy for extended periods of time although much lower in intensity. Why chance exposing young children to these levels of potentially bad environmental radiation? Money talks....
