"1.2 millegauss vs 0.8"??
But what does this _mean_. I'm certainly aware of the definition of a
gauss, but can someone translate this into useful English? (Remember
you're talking to software types here. ;)
Although there is no confirmed mechanism, and the utility industry is
fighting the very notion tooth and nail, prolonged exposure to 60 Hz
fields has been implicated in various ills, including leukemia, tumors,
and suppressed immune response. Children are at risk, perhaps more than
adults. Not just VDUs are implicated, either, but also electric
The issue has been so broadly discussed in the press lately (MacWorld,
New Yorker, TV morning shows and countless other mags and newspapers).
I (pre-)assumed that the topic would have a context, and the original
query seemed to come from someone knowing the issues (I left slug on as
a matter of potential interest). AND, the issues are complex, the
situation is not clear, I am no expert and everyone has to make their
1 milligauss is the currently "popular" level that we are encouraged to
maintain: 2 mG has been implicated in measureably increasing the risk of
leukemia in children, if I recall correctly. Remember though, nobody
knows how it works so noone can know what is and isn't safe --- not just
in terms of levels, but duration, field orientation, phases of the moon,
I have also spent most of my waking hours in front of emitters for the
last 20 years, and I now sit as far as I can and still read the damn
things (0.4 Mg, FYI).
