[Bernard Cohen]

> Just under 200 died from leukaemias, and 6,519 from other cancers. 
> The researchers say, that from their evidence, 1 to 2% of deaths from
> cancer among workers in this study may be attributable to radiation. 

       ---The statistical uncertainty (one standard deviation) is the 
square root of 6519 which is 81, or  1.2% of the result. So this 
evidence is essentially meaningless
