Elemental studies of any samples for example concrete are important for better characterization and inspection. Currently, many techniques have been applied such as x-ray, gamma-ray and etc. However further analysis is good to know without destroying the samples. Furthermore, simulations of any samples with Prompt Gamma Neutron Activation Analysis (PGNAA) are useful to experimentalist. In this study, Monte Carlo technique was used with two different type of software. The results were successful on elemental analysis from both techniques.
