| Predictions
and maps |
|
Predicted distributions of long-term, living-area
radon concentrations for nearly all counties in the U.S. |
| Geology |
|
Quantified the extent to which different types
of geologic information can be used to predict indoor radon concentrations. |
| Measurements |
|
Found ways of calibrating different types of
measurements without making multiple measurements in the same home (e.g.
predicting long-term living-area concentrations based on short-term basement
measurements). |
| Statistics |
|
Found ways of minimizing problems due to small
sample sizes, when trying to estimate geologic effects or county average
concentrations from small numbers of measured homes. |
