Re: Radon/Smoking relationship questions

I agree that you must be very careful about generalizations from various
parts of the U.S. That is one reason a nationwide ecologic study
based on short term, non seasonably adjusted, mostly lower living area
radon gas measurements as a surrogate for radon progeny exposure concerns
me a bit. Radon gas is radon gas everywhere in the United States,
but the effective dose from the progeny will vary by geography.
Regarding your other comments. Smoke and dust will not cause radon
progeny to plate out faster, it will cause it to stay suspended
longer.

is an additional thought: I don't believe you can extend your
conclusions about ventilation uniformly to all parts of the United
States. here are some examples of why:
1. In the Pacific Northwest there is relatively little home air
conditioning (central or otherwise). Moreover, many people use
electric baseboard heat instead of a central furnace because (until the
recent California energy debacle) electricity was reasonably inexpensive.
2. In New Mexico (and some parts of Arizona) homes are cooled using
evaporative cooling ("swamp coolers") rather than refrigerated
air. Evaporative cooling requires opening windows for ventilation.
3. Many new houses don't have basements or crawl spaces, but are
built on concrete slabs.
4. Out here is the Southwest, it is dry and dusty, and some of that
dust comes in small particles. It is also windy. I imagine
that dust blowing into a house would have much the same effect in plating
out radon and radon daughters as smoke.
5. Wood smoke would also plate out radon, in homes that are heated
with wood stoves.
Just some items for your consideration.
