The Department of Trade and Industry today released its latest set of emissions tests, putting paid to fears that mobile phone masts increase the risk of cancer.

The readings, carried out by the Radiocommunications Agency, tested 109 sites across the UK, including 82 school sites and 27 hospitals. Measurements ranged from hundreds to millions of times below the national guidelines.

"We are aware of public concerns and it is important to give the public the information they need," said Stephen Timms, telecoms minister.

"In 2003 it is likely there will be more mobile phones than fixed lines in the world, and with more than 45 million mobile users in the UK alone sending more than 45 million text messages a day, mobile phones are part of our every day lives [and] masts are the foundations on which this communications revolution is built," he added.

The research is the result of findings from the Stewart report released back in April 2000. The study said evidence did not suggest that mobile phone technologies were a risk to the public, but recommended a cautioned approach including the testing of base stations.

The highest ouput readings recorded were at Aintree hospital in Liverpool, however these were still more than 700 times below the limit.

All exposure limits are set by the International Commission for Non-Ionizing Radiation Protection.
