Abstract

In this paper, we used Monte-Carlo method for simulating the interactions of gamma radiation with matter, which composed of the three main types such as photoeffect, Comptom effect and pair formation effect. The software is designed based on C++ language for simulating gamma spectroscopy of some useful radioactivity sources such as Co60, Cs137, TC99, Ir192 Briefly, Seaweed drink, thanks to its nutritious ingredients, reasonable price and its good flavor, is a good choice for the beverage industry.
