In May 2000, an Independent Expert Group on Mobile Phones published a report that gave an assessment of the current state of research into possible health risks from mobile phones.
The Home Office asked the National Radiological Protection Board (NRPB) to provide comprehensive advice on possible health implications for users of Airwave. The NRPB commissioned a review from their independent Advisory Group on Non-ionising Radiation (AGNIR). This was published on 31 July 2001.
The report concludes that:
"Although areas of uncertainty remain about the biological effects of low-level RF radiation in general, including modulated signals, current evidence suggests that it is unlikely that the special features of TETRA mobile terminals and repeaters poses a hazard to health".
The Home Office has accepted the report and is taking forward all its recommendations for further research.
In November 2001, Mr Barry Trower wrote a report for the Police Federation on TETRA health and safety issues. The Home Office responded to the questions raised in the Trower report and is now awaiting the response of the Police Federation.
