Reward offer

[Bernard L Cohen <blc+@pitt.edu>]

	Five years ago, I published a paper in HEALTH PHYSICS
68:157-174;1995 presenting an analysis of lung cancer rates vs average
home radon levels in U.S. counties; it gave indisputable evidence that
county lung cancer rates (with or without correction for smoking) decrease
with increasing radon exposure, a sharp discrepancy with the predictions
of linear-no threshold theory (LNT). For the past five years, I have been
trying to find an explanation for that discrepancy. Several potential
explanations have been offered in papers published in HEALTH PHYSICS, but
in each case detailed analysis has shown that the numerical parameters
required for the suggestion to explain our discrepancy were completely
implausible. References to these analyses will be provided on request.
	As a further effort to find an explanation, I am offering a $1000
reward to any or all who propose a potential explanation for our
discrepancy that is consistent with LNT. The only requirement is that such
potential explanations be accepted for publication in HEALTH PHYSICS.
Note that this is a process over which I have no influence or control. As
soon as they are published, checks for $1000 will be sent. I will then
analyze the suggestions and submit my analyses for publication in HEALTH
PHYSICS. As noted above, such suggestions have been published several
times in the past, so I look forward to sending out several $1000 checks.
