Determination of sulfur in environmental materials by thermal neutron caputre prompt gamma-ray spectrometry

Thermal neutron induced prompt γ-ray spectrometry has been investigated as a technique to measure elemental S concentrations in complex materials. Comparison of analytical results of standardized materials shows the method to be accurate. Repeated analyses of 100 mg of elemental S gave a 1 percent standard deviation from the mean. The standard deviation increased with decreasing quantities of S. Standardized Orchard Leaves containing 500 μg of S had a 13 percent standard deviation from the mean of repetitive analysis. Calcium and K are the only common elements that directly interfere with the analysis
