Much controversy surrounds the effect of the electromagnetic fields of power cables on our health.
Naturally, this claim has sparked disagreements between scientists working for the electricity industry and scientists involved in independent research. Professor Henshaw's team at the University of Bristol placed a number of metal spheres in fields near Bristol and recorded the amount of airborne particles deposited on them. They found that pollutants were intensified in areas near power cables and deposited on the skin of people living or working nearby. To compound this, their study registered that the pollutants falling on these people affected them three times more than the same pollutants in areas away from power cables. We can understand Henshaw's theory by looking at the manner in which electromagnetic interactions take place between charged particles.
