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

Fri Oct 23 14:12:14 CDT 2009

"Below 0.5 Gy" does not relate to occupational (<0.05 Gy) or background
(<0.005 Gy).

What dose ranges are they referring to?

This should be fairly easy to verify by looking at long term residents
of areas with different background levels, and seeing if there is a
trend, once all confounding issues are accounted for.

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.
