Abstract
An experimental technique to determine the outcome of the interaction of gamma-rays with the given nanoparticles is contributed. The interactions involve gamma-rays of energies used in practical applications. The technique determines the outcomes directly. The variations in the number of counts and shape of pulse height spectra obtained before and after loading the nanoparticles into a liquid scintillator for given gamma-ray irradiation under identical conditions reveal the outcome of the interactions. Results reveal that the interaction of low-energy gamma-rays such as those from 241Am, 133Ba with the nanoparticles tested resulted in the emission of electrons from the nanoparticles. Among the nanoparticles tested, Gd2O3 emitted the greatest number of electrons. Photons with energy lying between 14 keV and 81 keV undergo greater interaction with the nanoparticles than those with other energies. High-energy gamma-rays transmit through the nanoparticles without interaction. The technique distinguishes the abundance and energy profile of electrons emitted from different nanoparticles upon irradiation with gamma-rays. Results enable test-selection of nanoparticles for applications such as the development of fast-efficient-large-affordable gamma-detectors, nanoparticle radiosensitization for cancer treatment, and the development of Pb-free efficient radiation shields for healthcare workers.
