New research finds no
connection between early childhood cancer risk and pregnant mothers' exposure
to mobile phone masts.
The study, published in the British Medical
Journal this week, compared British data
on childhood cancer rates of children between zero and four years old, and
cross-referenced them with mobile phone mast locations. The study involved over 7000 children.
The researchers found no link
between cancer risk in young children and mobile phone mast exposure during
their mothers' pregnancies.
The use of mobile phones in
has grown from just under 9 million connections in 1997 to almost 74 million in
2007. Worldwide there are over 4 billion cell phone connections.
May the results of a World Health Organisation study of mobile phone use and
brain tumor rates were deemed “not definitive", calling for more research.
The methodology of the report was also criticised.
Commenting on the report, John Bithell from the
Childhood Cancer Research Group at the University of Oxford,
said ‘moving away from a mast, with all its stresses and costs, cannot be
justified on health grounds in the light of current evidence.’
The research will go some
way to calming growing fears of the potential effects of mobile radiation.
Last week, San Francisco’s city council voted in favour
of a law which requires retailers to show the amount of radiation given off by
the mobile phones they sell.
It based its decision on an
Environmental Working Group report last September, which stated that ‘recent
studies find significantly higher risks
for brain and salivary gland tumours among people using cell phones for 10
years or longer.’
found that the Motorola Droid, Blackberry Bold 9700, HTC Magic and LG Chocolate
Touch were at the top of its radiation charts.
