The Department’s radiation protection research programme supports a number of studies investigating the possible health effects of electromagnetic fields (EMF). These range from laboratory work on possible cellular effects to large population studies. A study by Dr. Draper and colleagues of childhood leukaemia incidence and distance from power lines, funded under this programme and published in the British Medical Journal (BMJ) last year, has added to a large existing body of work in this area (BMJ Vol 330, 4 June 2005). In addition to its own research programme, the Department, along with the Health and Safety Executive, has supported the World Health Organisation’s International EMF Project since it started in 1997.
The Health Protection Agency’s radiation protection division (HPA-RPD) keeps the worldwide research findings on EMF and health under review. In 2004, on the basis of a comprehensive review of the existing body of research to date, the HPA-RPD (previously the national radiological protection board) recommended the adoption of new EMF exposure guidelines in this country. In addition, in view of the scientific uncertainties in relation to power frequency electromagnetic fields, the HPA recommended the Government
“consider the need for further precautionary measures”.
They have also noted that the majority of elevated magnetic fields are due to variations in the electricity supply and distribution system, the presence of substations and equipment in the home rather than proximity to high voltage overhead cables.
Practical precautionary measures are now being considered in detail by a stakeholder advisory group (SAGE) that includes the Government Departments, agencies, electricity industry, specialists and public concern groups.
