A substance analyzer utilizing Prompt Gamma Neutron Activation Analysis
for identifying characteristics of a substance and method of
manufacturing the same are disclosed. The analyzer is small enough to be
portable and to allow its use in many applications where current
analyzers cannot be utilized. The analyzer uses a neutron radiation
source and a gamma-ray detector to activate the sample material and
detect the prompt gamma rays emitted by the sample material. A novel
housing for such an analyzer and method for making the housing are also
described. Novel methods of operating such an analyzer including via a
communications network are also disclosed. Also disclosed are data
analysis methods that improve the accuracy and sensitivity of the results
of such material analysis.
