Dept of Health

Question: Pursuant to his Answer of 10th March, Official Report, c102-4W, concerning the incidence of cancer or other abnormalities in adults and children if he will (a) ensure that the two pilot studies relating to cancer incidence incorporate maps showing high tension power lines and the places of domicile and work of those affected and (b) consult the appropriate medical and health bodies concerning (i) the practicality and (ii) the desirability of mapping such transmission lines and the incidence of other abnormalities in their vicinity.

Answer: Mr. Spearing: To ask the Secretary of State for Health, pursuant to his answer of 10 March, Official Report, columns 102-4, concerning the incidence of cancer or other abnormalities in adults and children if he will (a) ensure that the two pilot studies relating to cancer incidence incorporate maps showing high tension power lines and the places of domicile and work of those affected and (b) consult the appropriate medical and health bodies concerning (i) the practicality and (ii) the desirability of mapping such transmission lines and the incidence of other abnormalities in their vicinity. [20153] Mr. Horam: The two pilot studies will explore the feasibility of investigating the possible relationship between the incidence of cancers and residential distance from electricity transmission and distribution systems. Neither of these studies is designed to investigate other abnormalities. However, the National Radiological Protection Board's advisory group on non-ionising radiation reviews work related to possible effects of electromagnetic fields on human health. It has been principally concerned with the risk of cancer but also keeps under review possible effects on other diseases and abnormalities as well as on developmental effects in utero.
