Fe76Mo8Cu1B15 amorphous metallic alloy is investigated after ion irradiation by 130 keV N+ and 80 keV H+ ions in order to ensure different degree of radiation damage. The depth of the peak region was calculated by the SRIM2008 code. Applicability of transmission and conversion electron Mossbauer effect measurements to distinguish between the bulk and surface radiation damage is demonstrated by using different irradiation conditions. The investigated alloy is characterized by weak magnetic dipole interactions due to its close-to-room Curie temperature. The implantation with H+ ions does not depict appreciable changes of the samples' surfaces and practically none in the bulk. On the other hand, 130 keV N+ ions caused pronounced effects especially in the CEMS spectra, i.e. on the surface because of the short range (about 150 nm) of the irradiating particles.
