The B.C. authors focus on a 2005 British study which found that there is an increased risk of 69 per cent for leukemia in children living within 200 metres of power lines. The risk is increased to 23 per cent if children live 200 to 600 metres of the lines. In Tsawwassen, the power lines literally run right over more than 100 homes.
