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.

I would suspect that, on average, the radiation workers who
received the
highest doses were from a lower socio-economic standing (e.g.,
the
decontamination workers). Socio-economics (read lifestyle) is a
well-established indicator of one's propensity for heart disease
and
shorter lifespan and I would wager that this is likely THE
causal factor
behind the finding rather that dose level which is likely only a
symptom
of the causal factor.

Importance: Low
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.

Fred
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 of human nature resents change, loves equilibrium, while another
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."
