Proton-rich Tc radionuclides have been identified as potential candidates for specific clinical and biological applications in the last decade. So far, these radionuclides have been produced either by proton-induced reaction on Mo targets or $\alpha$-particle-induced reaction on Nb targets. This article lightens two heavy-ion-induced production routes of ${}^{93,94,95,96}\mathrm{Tc}$ radionuclides through ${}^7\mathrm{Li}+{}^{\mathrm{nat}}\mathrm{Zr}$ and ${}^9\mathrm{Be}+{}^{\mathrm{nat}}\mathrm{Y}$ reactions and provides important cross-sectional information in the projectile energy ranges 37–45 MeV and 30–48 MeV, respectively. Excitation functions of those reactions have been measured using the stacked-foil technique followed by the off-line $\gamma$-spectrometric studies. Measured cross-sectional data have been interpreted comparing theoretical predictions of the two nuclear reaction model codes PACE-II and ALICE91. Experimental cross sections agreed with the theory. Measured production cross sections of ${}^{94,95}\mathrm{Tc}$ have been compared with those produced from the $\alpha +{}^{93}\mathrm{Nb}$ reaction.
