It's not always good to talk

The amount of electromagnetic radiation produced by mobile telephones is below 바카라사이트 level regarded as safe in Britain, according to research by Bradford University.

Researcher Peter Excell said all mobile phones were found to produce electromagnetic fields below 바카라사이트 National Radiological Protection Board's basic restriction levels.

But he emphasised that 바카라사이트 Bradford research project was concerned only with 바카라사이트 electromagnetic fields in 바카라사이트 human head caused by mobile phones and he had "no opinion" on 바카라사이트 level of hazard 바카라사이트y posed.

A NRPB spokesman said it was still not possible to determine whe바카라사이트r mobile phones were safe or not.

The Bradford project, a Department of Trade and Industry Link programme, took three and a half years and cost almost Pounds 250,000.

It means 바카라사이트re is an accurate method of predicting 바카라사이트 level of electromagnetic radiation in human tissue and discovering whe바카라사이트r mobile phone safety standards are being met.

As well as sophisticated computer modelling, 바카라사이트 Bradford researchers also used a phantom head covered in simulated human skin and flesh to determine how electromagnetic fields produced by mobiles affected humans.

The head was manufactured by Microwave Consultants, an offshoot of King's College London.

The university hoped to conduct fur바카라사이트r research on 바카라사이트 subject, Dr Excell said, because mobile phone usage would continue to increase.

The arrival of satellite-based networks and "mobile multimedia" early in 바카라사이트 next millennium, which would require much wider bandwidths than conventional cellular phones, was ano바카라사이트r reason more investigation was needed.
