	The paper presents the results of measurements of the spectrum and the radiation dose during irradiation of different construction materials with 2 MeV proton beam. There are shown the spectra of the induced activity of a number of materials and signals from the neutron detector. Based on the obtained results it is made the optimal choice of the target material, on which it is deposited a thin layer of lithium to generate epithermal neutrons used for boron neutron capture therapy of malignant tumors. Recommendations are given for materials desirable to use inside the high-energy beam transporting channel to reduce the dose of concomitant radiation.
