Exposure rate response analysis of criticality accident dectector at Savannah River Site

This analysis investigated the exposure response behavior of gamma-ray ionization chambers used in the criticality accident systems at the Savannah River Site (SRS). The project consisted of performing exposure response measurements with a calibrated {sup 137}Cs source for benchmarking of the MCNP Monte Carlo code. MCNP was then used to extrapolate the ion chamber`s response to gamma-rays with energies outside the current domain of measured data for criticality fission sources.
