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 …

Optimization of the Prompt Gamma Site at the McMaster Nuclear Reactor for in Vivo Neutron Activation Analysis
… # 4 at the McMaster Nuclear Reactor, involving prompt gamma in vivo neutron activation analysis. The project consisted of experimental and computational parts. The computational part was done using MCNP program, which simulates the neutron and photon transport in the medium. The first thing …

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 …
