- This part is pretty sad since Dean is big on taking shots at nuclear power

- It does not have to be low and it is not ALWAYS low. It is lower on
- average due to dilution and dispersion. :) On the UFla. campus, there
- are places outside certain buildings where the Rn levels in the outside
- air are high enough to prevent zero-level calibrations of Rn and Rn
- progeny detection equipment in the area.

- U averages 5 ppm in most soil/rocks with some spots as high as 15 ppm.
- It's there, just not in high enough concentrations to be ore.

- Rn is a big research topic here at UFla. (I'm part-time on this and
- my wife is the database manager for the State of Florida Radon Research
- Project's radon article database.)
-
- My dissertation topic, however, is a study of a potential mechanism of ionizing
- radiation's effect on certain organics common in the human body.
-
- Sorry this followup is so late, our newserver was down and so was I.
