A new paper has been published in the British Journal of Cancer.
The original “Draper” or “CCRG” study in 2005 found elevated rates of childhood leukaemia within 600 m of overhead power lines, for subjects from 1962-1995. The new study, by the same group, extends the period up to 2008 and finds that the risk seems to have progressively diminished over the decades and is no longer present.
The paper concludes:
“Conclusion: A risk declining over time is unlikely to arise from any physical effect of the powerlines and is more likely to be the result of changing population characteristics among those living near powerlines. “
