Prediction of 67Ga production using the Monte Carlo code MCNPX

► The production yield was predicted for the 68Zn(p,2n)67Ga, natZn(p,xn)67Ga and 67Zn(p,n)67Ga reactions. ► Reasonable agreement was obtained between experimental and theoretical production yield. ► The results confirmed that MCNPX code as a useful and accurate tool for the prediction of productivity. ► MCNPX was used to calculate the energy distribution of the proton flux on the Zn target.
