[ RadSafe ] Scientists discover possible radiation and heartdisease link

[NIXON, Grant]

I meant lower income jobs which, in turn, are associated with the risk
factors you mention. Can anyone speak to the rigor applied to the
sampling statistics and to the dose levels of the groups? I find that,
far too often, there is a serious problem with the sampling.

 

However, I recall hearing that that some of the workers at Chernobyl
died of heart attacks in the months and years following their elevated
exposures. I do not know if this was established formally /
scientifically in the literature or not.

Grant,

By "lower socio-economic standing" do you mean unable to afford health
care?  Hard-drinking? Smoking?

 

One would think that there factors are controlled for, but maybe not by
rigorous multi-regression analyzes.

	Opposite - less CV mortality with more radiation - must be true
in the
	NShipyardWS 
	with just 0.76 total mortality rate in those with > extra 0.5
rem vs
	workers otherwise identical,
	as published by Cameron.

	There is a link between radiation and cardiovascular disease.
See Darby
	et 
	al (BMJ Vol. 326, pp256-257, 2003) and our poster at the IRPA-11
	meeting.

part welcomes novelty, loves the excitement of disequilibrium. There is
no formula for the resolution of this tug-of-war, but it is obvious that
absolute surrender to either of them invites disaster."
