The end result is a fast, inexpensive measurement of isotopic uranium and radium in soils at a fraction of the time and cost required for traditional techniques. This technique has been used for analysis of soils for NORM concentrations in several states, but has not been approved for analysis of drinking water or radiopharmaceuticals.
