[ RadSafe ] Longevity and Radiation

[Wesley]

Radsafers,

I have been thinking of "longevity" and how one would do epidemiology with
this parameter.

I suppose longevity is average age of death for a group of people such as
residents of a county or state or country.

But longevity would be highly dependent on average age of the group. In an
extreme example, take county A and B. If all people over age 50 in county A
moved to county B. And all people under age 50 in county B moved to county
A. Then the longevity in county A must be well under 50 and in county B the
longevity would be well above 50. This would be independent of environmental
conditions and average health status of the residents.

So how would you correct "longevity" for average age in a group?

Just thinking out loud on a hot summer day.

Regards, Wes

Hi Bernie,

CDC Wonder has longevity data.  But those results were done with your radon
data (and the EPA radon data?) a couple of years ago by Ruth Sponsler.  Did
that ever get pub'd?
