Okay, But what about this statement:

"For every 10 mSv increase in low-dose ionizing radiation, the risk 
of cancer increased by 4.4 percent in women and 2.1 percent in men. "

Much like the results you get from comparing statewide cancer rates to background radiation, what you leave out of the model is much more important than what you put in.
