Ed,  How about FEAR. Bad things can happen to those who get the wrong answer on 
government sponsored research. Beneficial radiation effects are definately a 
wrong answer.

Every few years this comes up, and every few years I feel the need to
address these allegations.



During my last few years at DOE, I worked for the manager who had chartered
and funded this project at Naval Reactors (NR).  When I asked him about why
it was never published, he gave me the simple answers - (1) at the time the
study was done, the "excess benefit" results were not considered to be
significant - NR's reason for doing the study was to be sure that nobody was
being unduly harmed and the study verified that to be the case; and (2)
since it was an internal study for NR purposes, publication was not in the
original scope of the project - when it was recognized that they should
publish, NR was willing to put more money in but the researcher had already
gone on to other projects and was not interested in working on the
publications.



Case closed; no suppression, no conspiracy.



Besides, although I am not an epidemiologist I do understand the scientific
method quite well.  The statistical tests one uses are based on the
hypothesis one is testing.  In this study they were trying to determine if
there was "excess risk" with exposure.  I suspect that many things would be
done differently if they were testing for "absence of risk" or "excess
benefit."  Consequently, it is not clear that one could jump to the
conclusion that the study's results are valid for any purpose other than
what the study was designed to detect.



I have a copy of the report in my basement, and I know there are other
copies circulating around.  But since it is a full 3" (oops, 7.62 cm) 3-ring
binder full of paper, I'm reluctant to offer to scan it for everybody.  If
you really need it and can't find it, I'll find out what it would cost to
scan it at FedEx/Kinko's if somebody wants to make a donation.
