It meant only 10 years of the total window examined had a radon measurement 
assocaited with it. The area of the home with the greatest radon gas variation 
is the basement (see paper below).  Studies have not noted higher 
concentrations of radon gas near the walls.  Perhaps thoron, but not radon 
gas.   

The North American Pooling did not use retrospective radon detectors.  Please 
contact me at bill-field at uiowa.edu for follow-up questions on that detector.
