The Th-212(n,2n)Th-231 reaction cross-section was measured relative to the Fe-56(n,p)Mn-56 and Al-27(n,a)Na-24 reaction cross-sections with the activation method for neutron energies up to 11 MeV. Neutrons were produced by the H-2(d,n) reaction in the 5.5 MV Tandem accelerator of the NCSR "Demokritos". The characteristic gamma lines of the product nuclei Th-231 (25.646 keV) and Mn-56 (846.771 keV) or Na-24 (1368 keV) were measured with an 80 mm(2) Si(Li) and a 20% reverse-electrode coaxial germanium detector, respectively. The results indicate that our values are in agreement with the JEF2 and BROND2 database values up to 9 MeV and slightly higher than those from all the libraries for higher energies.
