Description	Fe(76)Mo(8)Cu(1)B(15) and Fe(74)Nb(3)Cu(1)Si(16)B(6) amorphous metallic alloys were exposed to ion bombardment with nitrogen ions and protons to ensure different degree of radiation damage. The radiation damage profiles were calculated in the %22full cascade%22 mode. Conversion electron Mossbauer spectrometry was employed to scan structural modifications in the surface regions of the irradiated alloys. In Fe(76)Mo(8)Cu(1)B(15), the irradiation with 130 keV N(+) has caused a significant increase of the hyperfine magnetic fields and isomer shift due to changes in topological and chemical short-range order (SRO), respectively. No appreciable effects were revealed after bombardment with 80 keV H(+) ions. Fe(74)Nb(3)Cu(1)Si(16)B(6) amorphous metallic alloy was irradiated by 110 keV N(+) and 37 keV H(+) and only changes in chemical SRO were revealed after bombardment with nitrogen ions. The observed alternations of the structure depend primarily on the total number of displacements of the resonant atoms which are closely related to the fluence as well as type and energy of the incident ions.
