Investigative for no-carrier-added87m,gY production by the proton-induced on89Y.
The radioisotope87Y is one of the candidates for the SPECT and87Y/87mSr generator due to its suitable half-life and decay properties. The proton-induced on the89Y target can be used for the production of87Y. The present perusal calculated the excitation function for the both89Y(p,x)87m,gY direct reaction and decay of87Zr via89Y(p,3n)87Zr →87mY →87gY indirect reaction using the TALYS-1.8 code. To simulation the production of87m,gY nuclide, the target thickness was designed based on the stopping power calculation by the SRIM-2013 code. The Monte Carlo code GEANT4 was used to simulate the transport of protons through the irradiation assembly. Then, the cumulative integral yield of the87m,gY has been calculated directly after the decay of87Zr radionuclide entirely. These results were in good agreement with the theoretical and reported experimental data. Eventually, the integral yield of the87m,gY was calculated by the indirect method from87Zr decay after separation the zirconium. This work provides the basis for theoretical appraisement of the use of no-carrier-added87Y as radiopharmaceutical for the purpose of medical applications.
