Alasdair Philips, a founder of Powerwatch, the U.K. activist group, is calling for "urgent action" to protect children from an epidemic of brain and other tumors in 10-30 years. He says that it's now "morally irresponsible" to allow youngsters to use mobile phones. Philips's call to arms follows word that two new Interphone studies point to a significant tumor risk, as well as his own analysis of U.K. data that show a general increase in temporal and frontal lobe tumors. A few months ago, a British group reported that they could see a rise in these tumors but then dismissed the trend as being of no importance. Philips also decries the fact that the U.K. researchers did not share their Interphone data with Elisabeth Cardis, the project leader, for the analysis of tumor location relative to a phone's radiation plume. Philips's appeal has already been translated into French by Teslabel, a partner group in Belgium.
