Study advises limiting children's use of mobile phones

Though no conclusive evidence currently exists that mobile phones are harmful, a cautious approach of risk management, especially in relation to children, should be taken by the government, according to the study, published by the U.K.'s National Radiological Protection Board (NRPB). "
