Effect of addition of cerium (III) nitrate hexahydrate on gamma ray interaction properties in acetone at various gamma energies obtained by Compton scattering technique

Abstract

The objective of the present work is to assign radiation interaction parameters to the solutions of cerium (III) nitrate hexahydrate [(Ce(NO3)3.6H2O)] in different concentrations dissolved in acetone [(CH3)2CO]. The photons scattered from cylindrical aluminum target result in secondary photon beam of desired energy and were detected using 2″ × 2″ NaI(Tl) scintillation spectrometer. The results show a decrease in mass attenuation coefficient (μm), effective atomic number (Zeff) and Electron density (Nel) with the increasing gamma photon energies and decreasing concentrations. The values of Computed tomography (CT) number, interpreters of CT scan, are found to be increasing linearly with increase in concentration and exponentially with increase in Zeff. These results show a good agreement with the theoretical values obtained from WinXCom.
