[ RadSafe ] 'How Low Doses Of Radiation Can Cause Heart Disease And Stroke'

[Monty Charles]

I don't think one can be complacent about this. Evidence is slowly mounting 
in support a low dose effect (below 0.5Gy) for non-cancer diseases. One 
factor which led ICRP (Publication 103) and UNSCEAR (2006) not to 
include non-cancer risks in their general low dose risk estimates was the 
lack of an underlying biological mechanism. The paper of Little et al is worth 
a read. Their mathematical model has a reasonable biological basis and 
predicts LNT for cardiovascular disease. The authors point out the 
limitations of the the model - but it has the great virtue of being testable by 
in-vitro, animal or human studies. It gains plausibility by predicting excess 
relative risk values in line with observed values from a range of 
epidemiology studies. The mathematics will be intractable to many but the 
table which compares model  predictions with radiation epidemiology data is 
clear.
