POWER LINES NOT A CANCER RISK FOR CHILDREN
The potential link between overhead power lines and childhood leukaemia has been discounted by new research.
Researchers from the National Radiological Protection Board (NRPB) in Oxfordshire and the Brunel Institute for Bioengineering looked at the effect of electric power frequency magnetic fields on human chromosomes. There has been some concern in the past that the electromagnetic fields from power lines and household appliances might make children more susceptible to leukaemia.
The theory is that the magnetic fields might prevent cells from repairing everyday DNA damage, so the scientists created a lab experiment where they blasted cells with radiation. They discovered that the cells were able to repair themselves naturally, despite being subjected to magnetic fields stronger than those experienced in British homes.
As lead researcher Dr. David Lloyd explained, "Some studies in the past have thrown up evidence of a weak link between unusually strong magnetic fields experiences in some homes, and leukaemia in children. We tried to produce this effect in cells in the lab, but couldn't find it even using magnetic fields stronger than people would experience in everyday life."
"Studies like ours have so far failed to uncover a pathway by which magnetic fields could cause childhood leukaemia - and it's looking probable that none exists," he added.
Sir Paul Nurse, from Cancer Research UK, said, "Many people have been concerned that the electromagnetic fields we are exposed to on a daily basis may have an impact on our health. The result of this study contributes to allaying these fears."
