Simon Studholme died of leukaemia in 1992. His bedroom was next to the electricity meter and outside the house stands an electricity substation. Now the family lives in the half of the house furthest away from it, convinced that electromagnetic fields were responsible for Simon's disease. His father Ray says: "You take responsibility for your children. You don't let them cross the road on their own - you're there, holding their hand. For God's sake, you don't think that they're going to be in danger when they go to bed at night. Tonight, Sarah Spiller asks why the public have been told nothingof the possible link between electricity and childhood cancers, when statistical research in the US and Sweden suggests that the link exists.
