Radiation hardening caused in molybdenum by reactor neutron irradiation and 28-MeV alpha-particle bombardment is studied. 28-MeV alpha-particles are used as a model irradiation simulating CTR radiation effects. It is shown that at earlier stages of irradiation neutrons are more effective in the sense of hardening influence, but as the damage level increases, alpha-particles become the stronger hardening irradiation. It is concluded that radiation hardening of molybdenum is determined by defect structure in whose creation both low and high energy processes of radiation damage take place. PKA spectra are of great importance in the production of hardening defects.
