Title: exposure levels
Post by: viet on April 29, 2013, 02:03:59 AM

if a radon exposure level of 4 pCi/L for 8 hrs, for dying from lung cancer is 73 out of 10,000 and an exposure level of 8 pCi/L is 150 out of 10,000.
 How would I find the number if it was 20 pCi/L for 8 hr exposure? are there any special equations I need to use?

I would say its 4/73 ~ 8/150 ~ 20/x
0.055~ 0,0533  average. 0,054 means ~ 370
