Warning over child cellphone use

Parents have been advised not to give cellphones to children under 8 years old, despite a continuing lack of concrete evidence that radiation levels endanger health.

Sir William Stewart, the chairman of Britain's National Radiological Protection Board, said his worries were more serious than five years ago, when he first reported on cellphone safety.

Although there was still "no hard evidence" electromagnetic radiation levels caused harm, the number of cellphone users was constantly increasing, he said.

A precautionary approach was needed because the effects might not be known for decades.

Statistics New Zealand said households with at least one cellphone rose from 59 per cent in 2000-01 to 71 per cent in 2003-2004.

Sir William said if anyone was at risk, the most vulnerable group was likely to be children.

However, Auckland Medical School physician Dr David Black said: "I think it is inappropriate to ring alarm bells. I know of no reason why children should be more vulnerable."

He said New Zealand already had a precautionary approach and Government advisers would discuss the report in February.

A major World Health Organisation report is also due to come out in the next few months.
