[ RadSafe ] Scientists discover possible radiation and heartdisease link

Grant,
  I believe that the increased death rate to Chernobyl worker was probably due to declining economic opportunites with the break up of the Soviet Union, lack of health, care, high rates of alcohol consumption and smoking.  I am not sure if heart disease was studied in the Chernobyl workers per se.

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.
