Abstract

To estimate chlorine content in samples and to explore possible applications in neutron dosimetry, neutron induced prompt gamma spectra emitted from NaCl sample are experimentally measured using an AmBe neutron source and a NaI(Tl) detector. Theoretical estimate of such gamma emissions from 36Cl* are done using the EMPIRE 3.2 code and the most intense gamma peaks at 0.517 MeV, 0.788 MeV, 1.16 MeV and 1.96 MeV are identified. A good agreement between the gamma intensities and the chlorine concentration was observed for 1.16 MeV and 1.96 MeV gamma peak. The gamma intensities found to be more sensitive to the presence of hydrogen due to increased thermalization of neutrons. The differential energy response of chlorine and hydrogen in aqueous solution of NaCl can be combined to approximate the energy dependent neutron dose response.
