Test of the Linear No-Threshold Theory of Radiation
Induced Cancer,
(Abstract) by Bernard L.

Proceedings of the 38th SAAPMB and the 1st SARPA Congress, May 12, 1998.
"Data on lung cancer mortality rate vs mean radon
exposure in 1729 U.S. Counties (comprising 90% of the U.S. population) were
used to test LNT. The LNT predicts a mortality increase with increasing
radon concentration by 7.3% per pCi/L; whereas the data show a decrease of
about 8 (+/-0.8)% per pCi/L, a discrepancy of 20 S.D. Extensive efforts to
explain this discrepancy have been unsuccessful in even appreciably reducing
the discrepancy. Requirements on some unrecognized confounding
factor that can explain our discrepancy make its existence highly
implausible. Our data do not conflict with any other known data. By
far the most plausible explanation of our discrepancy is gross failure of
LNT in this low dose region where it has never been experimentally tested."
