AW: AW: AW: AW: [ RadSafe ] Cameron's refutation of "Alara Does Work" - Preemployment physicals

[Rainer.Facius at dlr.de]

Dear John:

True, but frankly, NO epidemiological study, including the ATB survivor data, are free from bias/nuisance variables/confounders. Thus, strictly adhering to your advice would bereave us of essentially the whole human data base, of which the NSYW study represents a not insubstantial fraction which I would not ignore without more solid reason than just "may have been biased" which is true for all others, too.

Kind regards

Rainer,
If you accept that the data may have been biased, why do you not just move on to more relevant studies? 
Science is not based on only one study.  It is a body of work that establishes proof.
