The paper shows the results of experimental gamma spectra obtained with a thorium 232Th target and an aluminum collector irradiated at the JINR Synchrocyclotron with the internal beam of energies of 100 and 600 MeV. For 232Th there were identified 258 and 222 gamma lines that belong to 45 and 55 nuclides, respectively. For Al - 238, 330 lines and 81, 119 nuclides, respectively. The cross sections of fragmentation of the 232Th and Al nuclei under the interaction with protons 100 and 600 MeV was determined. A comparison of the obtained cross sections of the reaction with theoretical calculations was performed.
