A large part of the programme is about the possible biological effects of low intensity TETRA signal. The NRPB recommendations are very thorough and cover all aspects of the problem, from basic cell biology to possible effects on high level brain activity. The rest of the programme includes detailed assessment of the energy transmitted by TETRA base stations and terminals.
Most of the research is long term and requires a rigorous scientific programme. If at any stage the research indicates a possible hazard to health, the Home Office will immediately make the results available and take appropriate action.
Results already obtained by the Home Office indicate that the specific absorption rates of currently used Airwave terminals are well within international safety guidelines.
The Home Office have commissioned the Defence Science and Technology Laboratories (Dstl) to undertake an experimental programme on the possible biological effects of TETRA technology. The first results are expected in April 2002.
The Home Office has also commissioned Microwave Consultants Limited to make detailed assessments of body-worn Airwave equipment.
Further work within the framework of the Mobile Telecommunications Health Research programme is currently under discussion.
