_______________

This is an exceptionally important paper.
The results MAY be rubbish.
And they MAY trigger changes in our interactions with power lines.
Epidemiologists have been at loggerheads for decades as to whethe rpower =

lines cause cancers and, if so, how.
There have been questions about field strengths and more.

Now, if MAY be that much of what was claimed is both true and provable.

      Abstract
      A case-only study was conducted in 123 patients with sporadic acute =

adjusting for age, gender, parental education and occupation, indoor and =

outdoor pesticides use, presence of television sets, refrigerators and =

microwave ovens in children's rooms and the presence of chemical factories =

or telecommunication transmitters within 500 m of the houses. The results o=

"the distribution of leukemia among children living hear high voltage
power lines or transformers is not random; rather, it affects children
carrying a certain genetic variant=97that is, the ability to repair DNA
breaks=97vastly more often."

"Researchers have long thought that EMF radiation caused DNA breaks,
but couldn't figure out how. Shen's research points to a different
mechanism; the EMF radiation doesn't cause the breaks, but inhibits
DNA repair, particularly in children that have a weakened repair
mechanism to begin with."

We're going to be adding significant transmission infrastructure over
the next century - are we going to write regulations that require
magnetically shielded, buried transmission lines going forward?  Or
just tell people not to sleep or spend significant time under them?
