I read in sci.electronics.design that Dirk Bruere
wrote (in ) about 'Any ideas on
measuring radiation in the home ?', on Wed, 9 Oct 2002:
>So, how does that compare to living near a HV AC powerline?
There are MANY differences between the fields generated by an electrical
storm (broadband, very large fluctuations) and a power line (narrow
band; more or less continuous).
The fields from power lines DON'T occur naturally. But people have been
living near and under power lines for around 70 years in many countries.
If there were any harmful effect, sufficient to justify all the jumping
up and down and screaming, it would be rather easily detectable by now,
whereas even the most prejudiced analyses show nothing definite.
OTOH, urban legends and scare stories are rife, many published by people
who demonstrate clearly a total absence of understanding of the subject.
My favourite is a claim of a 60 V/m **d.c.** electric field attributed
to a 50 Hz mains water heater. This is a heating element, sealed in a
steel tube, immersed in 100 L of water, in a water-tight copper casing.
'Oh, yes, the field disappeared when the heater was switched off.' Yes,
and I'm the Good Fairy Sunbeam.
