Abstract

The ascend of interest concerning 86Y and 90Y90 radionuclides which lies among the most important radionuclides for therapy of organic tumours has driven up the demand for the radionuclides. The use of enriched Strontium radionuclides for accelerating the production of 86Y via the 87Sr (p,2n) 86Y and 90Y through 89Sr (d,n) 90Y reactions respectively is thus essential in order to generate a wide variety of 86Y and 90Y labelled radiopharmaceutical drugs for treatment benefits of patients. However, these routes, though more plausible than nuclear reactor method, is inundated with a number of competing contaminant radionuclide such as 84Y, 85Y, 87Y and 88Y. In this paper the Q-value and reaction cross sections of the 87Sr (p,2n) 86Y and 89Sr (d,n) 90Y reactions were calculated using GEANT4 toolkit and the effects of Q-Value in optimizing the production of 86Y and 90Y were discussed to evaluate the most favorable nuclear data for optimal production of the nuclides. Q-Value of -14.456 MeV and 5.3451 MeV were found to be most feasible for 86Y and 90Y production respectively along with respective maximum cross sections at incident energy level of 25 MeV and 17.5 MeV. This nuclear data will be very useful for radionuclide production of 86Y and 90Y using accelerators or cyclotrons.
