In this study, proton-irradiated tungsten targets, up to 2.6 GeV, were investigated for the purpose of the experimental cross-section measurements. Radiochemical separation methods were applied to isolate the residual long-lived alpha-emitters 148 Gd, 154 Dy, and 146 Sm and the beta-emitters 129 I and 36 Cl from proton-irradiated tungsten targets. The molecular plating technique has been applied to prepare 148 Gd, 154 Dy, and 146 Sm samples for alpha-spectrometry. Production cross-sections of 129 I and 36 Cl were determined by means of accelerator mass spectrometry. The results are compared with theoretical predictions, obtained with the INCL++-ABLA07 codes, showing good agreement for 36 Cl and 148 Gd, while a factor of 4 difference was observed for 154 Dy, similar to the results obtained for tantalum targets.
