Activation cross sections of 110,113g,117mSn, 108m,108g,109g,110m,110g,111g,113m,114m,115m,116m2,117m,117gIn and 111m,115gCd radionuclides produced by alpha induced nuclear reactions on natural Cd were measured from 40 MeV down to their respective threshold energy with special emphasis on production of theranostic radionuclide 117mSn. Standard stacked foil irradiation method was employed and the gamma activity was assayed offline using HPGe based gamma-ray spectrometry. Thick target yields of these radioisotopes were also deduced using the experimentally measured cross sections. Experimentally obtained data were compared with the literature data from the previous measurements and with the evaluated data of the theoretical nuclear reaction model code calculations TALYS 1.96 from TENDL-2021 nuclear data library for all the radionuclides. The present data are in general found to be in good agreement in most of the cases with the earlier published literature data while significant disagreements are found for 110gIn and 111mCd when compared with TENDL-2021 data. Optimal production of 117mSn with minimal contamination using cyclotron is discussed.
