Re: Question on Background Radiation (none / 1)
by dense I mean it weighs a lot per unit volume, and hence tends to sink.

Ading to JakeS: you do mean atomic weight in the end (radon mass per unit volume at a given air pressure depends on concentration). But it is actually true that radon can concentrate in 'poodles' due to stratification of still air (in a basement or mine).

"radon can concentrate in 'poodles'"


A victim, yesterday.

I don't know what other definition of density there is apart from molecular weight, for gases.  I think you are confusing with concentration.

I'll leave the poodles for LondonAnalytics.
