Norm,

The problem is that the sample is not a statistically valid sample. It 
is biased from the get go. For instance, there was no Design of 
Experiments done (in the statistical sense). It a real statistical 
analysis, the point is to prove or disprove the null hypothesis. That 
wasn't done in this study, since that wasn't the goal. What was the 
Control Group used in the study? What other areas around the 
USA, as well as foreign countries, were used to collect teeth, not 
only around a nuclear power station, but in areas that were far from 
a nuclear power station? What other information regarding the 
those who provided teeth was collected, to make for an appropriate 
epidemiological study? I don't believe there was any study or data 
collected to determine the lifestyle, which could have also 
contributed to any of the results collected.

As a study, all that was done was to collect some teeth. There 
was nothing scientific about the collection, the analysis and most 
definitely, the most high unscientific study when it came time to 
define the conclusions of the study.

While I have studied statistics from some of the best in the world, 
JUSE counselors, there are others here on Radsafe who are far 
better capable to address the significant flaws from a scientific 
sampling, analysis and conclusions.
