Abstract

Since August 1989, "'Rn groundwater samples from across the state of Arizona have been collected and analyzed using liquid scintillation. Of the 253 specimens acquired, 65% have "'Rn concentrations above 11 Bq L-' (300 pCi L-'), while 16% have "'Rn activities over 37 Bq L-' (1,000 pCi L-'). The geometric mean "'Rn concentration for all the wells tested is 13 Bq L-' 4; the arithmetic mean is 37 2 122 Bq L-'. Using the geometric mean, it is estimated that an additional tracheobronchial lung dose equivalent of 0.19 mSv y-' 13.9 is delivered to Arizona residents from the well water to home pathway.
