Analysis of gas differential diffusion through porous media using prompt gamma activation analysis
… Here I present a novel methodology for using prompt gamma activation analysis to measure the effective diffusivity of noble gases in a porous medium. I also present a model to estimate the connectivity parameter of a soil from measurements of its saturated conductivity, macro porosity, and …

COMPARISON OF NEUTRON NON DESTRUCTIVE METHOD AND CONVENTIONAL CHEMICAL METHOD FOR CHLORIDE MEASUREMENT IN CONCRETE
… a neutron-based nondestructive testing method, Prompt Gamma Activation Analysis (PGAA) against the destructive wet chemistry method ASTM C-1152 currently used to determine the chloride concentration in concrete. Two modes of PGAA operation were tested. One was to use PGAA with a slit collimator …

Identifying short-lived fission products by delayed gamma-ray emission
… The majority of the peaks were composed of gamma-rays from multiple nuclides. The peaks created by gamma-rays from decays of a single nuclide were used to calculate the detection limits of the system. Using the beam chopper system, 21 peaks would be above the detection limits of our system …
