There exist many radioisotopes known as suitable for the diagnosis of cancer diseases and for many other medical field uses. One of the most known and widely used among them is Ga-67 due to its preferable specifications such as 3.26 days of half-life and possibility of production from cyclotrons via charged particle induced reactions. In this study investigations of the cross-section calculations for different production routes of Ga-67, by considering the charged particle induced reactions on different isotopes, and the effects of level density models to these calculations have been aimed. Moreover, the total activity calculations for Ga-67 have been performed for these investigated reactions. The cross-section calculations have been done via TALYS 1.8 code by employing constant temperature fermi gas, back-shifted fermi gas, and generalised superfluid models. Obtained calculation results have been reviewed by comparing them with not only each other but also literature data taken from Experimental Nuclear Reaction Data (EXFOR) database both visually and statistically.
