Through correlation and principal component analyses, as well as a random forest model (RF), it was determined that the groundwater 222 Rn concentration was affected by several factors, including the hydrogeochemical environment, its associated water-rock interactions, the provenance of aquifer ...
"Because radon is radioactive, we can take the liquid and inject it into a cocktail that fluoresces when something undergoes radioactive decay," Jacobson said. "We then put that into a machine that counts the number of fluorescence incidents." From that measurement, the team was able to det...
Trends became obvious when geologic maps were compared to the areas of radon potential. Most of the high potential sites lie on highly permeable Missoula Flood sediments in north Portland which have a granitic provenance.BURNS, Scott F
