[ RadSafe ] cancer "risk" near certain nuclear plants vs hormesis

[howard long]

John Jacobus and Radsafe readers,
Analysis of incomplete data of Taiwan's CO60 contaminated apartments 
was not the fault of Chen, Luan et al,
but of bureaucrats like yourself, John, who restricted access to data 
showing their jobs were unnecessary!

The  3.5/116 extreme difference below could not be explained by incomplete data
with <1/10 that effect!

I, B Cohen and other "respectable epidemiologists" do indeed find it, like 
Cohen's data on radon and lung cancer, inconsistent with the LNT that pays 
John's salary.

Dr. Long is certainly correct.  Selection or bias is a "sin" in epidemiology.  So is cherry-picking data or incomplete analysis of the data, as in the Taiwan study which is so seriously flawed no respectable epidemiologist would touch it.

SELECTION = SIN (foundation of epidemiology)
Chance alone will give 5 of every 100 studies "statistical significance" (p .05 by chance alone),
close to the 37 cases where just 17 were expected, on the average. 
Would they have reported negative studies? How many were considered?

Experiment is needed. Natural experiment of Taiwan apt 0.4Sv addition from CO 60 in the steel
(hundreds of times any addition to the German dose, certainly less than its radon spa dose)
to 10,000 residents for 9-20 years, resulted in only 3.5 cancers/100,000 person -years
vs 116 expected, more likely prevention of cancer by chronic radiation. 

Did you hear the story about the statistician who drowned, while wading across a creek 
that averaged just 6" deep?
