Abstract

Shielding materials for nuclear gamma radiations are important in applied nuclear radiation fields such as nuclear radiation therapy, radiation health physics, nuclear reactors shielding, storage of radioactive materials etc. In addition, study of interactions of gamma radiations with different materials are also prime important in basic physics. In view of this, mass adsorption coefficients of gamma radiations for Aluminum, Lead, Teflon for Cs-137 gamma radiations are measured and results are reported in present work. Gamma mass absorption coefficients are calculated using NaI(Tl ) scintillation detector and 8K Multichannel Analyzer gamma ray spectrometer system. The values of gamma ray mass absorption coefficients for Aluminum, Lead and Teflon are found to be 17.12 cm2/gm , 0.43 cm2/gm , 16.80 cm2/gm . The results are in good agreement with the literature values.
