"Comparison of Gamma Ray Attenuation Coefficient between Marble and Limestone Using NaI Detector" Nanda Phone Lin Wai Hnin Thidar Soe Htet Htet Aung "The aim of this research is to study the physical properties of marble and limestone and their transmitted intensities of gamma ray of each sample. The detector used in this research was 2 in x 2 in NaI (Tl) Scintillation detector with 5μCi of 137Cs gamma radiation source. It can be seen that the density of marble is denser than that of limestone. The attenuation of marble sample is 0.275cm-1 and the limestone sample is 0.234 cm-1. From these results, marble sample is more attenuate than limestone sample. It can be concluded that, the denser materials are more attenuate for radiation intensity" 2022-08-12 https://meral.edu.mm/records/8454
