Utilization of GEANT to calculation of production yield for Zr by charge particles interaction on Y, Zr and Sr.

The Zr, is one of the radionuclide with near-ideal properties for PET due to its suitable half-life and decay properties. The cross-section of Zr via Y(p,n)Zr, Y(d,2n)Zr, Sr(α,xn)Zr and Zr(p,pxn)Zr, were calculated by the TALYS-1.8 code to predict the optimum range of charge particle energy. The Monte Carlo code GEANT4 was used to simulate the formation of Zr in the target body. The simulated Zr yield was in good agreement with published experimental results in the optimum energy range. According to the calculations, the Y(p,n)Zr was superior to the other reactions useful to medical application.
