Mr. Williams O'Brien
To ask the Secretary of State for the Environment if he intends to issue planning guidance notes to local authorities on building near to high-voltage power lines; and if he will make a statement. 
§ Sir Paul Beresford
The National Radiological Protection Board, which advises the Government, local authorities and industry on these matters, has already issued guidance on the known health effects of proximity to high-voltage cables and other sources of 453W electromagnetic fields. The board will not hesitate to give further advice on protection if the scientific evidence indicates that it is necessary.
