BEIJING, June 3 -- A new study has
found that children who live within 200 metres of the overhead electricity
cables have a 70 percent increased risk of developing leukaemia.

However, the researchers, led by Gerald Draper of the
Childhood Cancer Research Group at the University of Oxford, were unable to
offer any explanation for their findings.
"We don't think this is a direct effect of the
magnetic field at 200 to 600 metres. There might be some other indirect, remote
mechanism that we don't understand and we can't measure. Or the findings might
be due to chance," a report posted on The Independent Web site quoted Dr
Draper as saying.
There were no grounds for taking any action such as
moving house on the basis of their results, according to Dr Draper. The
study, launched in 1997, was incomplete because the researchers had not
measured the size of the magnetic field generated by the power lines and
compared it with that from other sources, he said.
The study, involving almost 10,000 cases over 33
years, found the effect was small but statistically significant. The
result appears in Friday's British Medical Journal. Enditem
