[ RadSafe ] LNT Dogma?

Here is someone who I think is not known for quality research being pushed
out to journalist and public records access community.

I am familiar with the Rocky Flats Nuclear Power Plant problem of
questionable risk assessment and health warnings; and Congressional
direction to investigate.

I can't provide a sample of a good FOIA request.  But I can show you where
to find a new medical publication re: the history of the flawed radiation
risk assessment models and how it has impacted public policies over just
about all chemical and environmental exposures. This paper, its author, and
like-minded researchers are shaking up how chemical and environmental risk
assessments are done when setting Permissible Exposure Limits.

Abstract:

"This paper is an historical assessment of how prominent radiation
geneticists in the United States during
the 1940s and 1950 ssuccessfully worked to build acceptance for the linear
no-threshold( LNT) dose–
response model in risk assessment,significantly impacting
environmental,occupational and medical
exposure standards and practices to the present time. Detailed
documentation indicates that actions
taken in support of this policy revolution were ideologically driven and
deliberately and deceptively
misleading; that scientific records were artfully misrepresented;and that
people and organizations in
positions of public trust failed to perform the duties expected of them.
Key activities are described and
the roles of specific individuals are documented. These actions culminated
in a1 956 report by a Genetics
Panel of the U.S. National Academy of Sciences (NAS) on Biological Effects
of Atomic Radiation (BEAR). In
this report the Genetics Panel recommended that a linear dose response
model be adopted for the
purpose of risk assessment, a recommendation that was rapidly and widely
promulgated. The paper
argues that current international cancer risk assessment policies are based
on fraudulent actions of the U.
S. NAS BEARI Committee, Genetics Panel and on the uncritical, unquestioning
and blind-faith acceptance
by regulatory agencies and the scientific community."

One really needs to read the whole paper to get the gist of how it impacted
Rockey Flats workers and others.

"Collectively,these deceptive actions became highly significant when they
facilitated an unchallenged and blind-faith adoption of the Linear Dose
Response (LDR) model for cancer risk assessment of ionizing radiation and
later of chemical carcinogens"...This paper follows an historical timeline,
starting with the
professional/scientific relationship between Hermann Muller and Curt Stern
and their subsequent collaborations on ionizing radiation during the
Manhattan Project."
