In its report, released today, the board of the NRPB reaffirmed its call for a “precautionary approach” to the use of mobile phones. One of the key recommendations is that “particular attention be given to how best to minimize exposure of potentially vulnerable subgroups such as children.” In the NRPB press release, Sir William Stewart, the chair of the board, states that, “The fact is that the widespread use of mobile phones is a relatively recent phenomenon and it is possible that adverse health effects could emerge after years of prolonged use.”
