The response of the structural, magnetic and mechanical properties of amorphous and nanocrystalline Fe{sub 73.5}Cu{sub 1}Nb{sub 3}Si{sub 13.5}B{sub 9} to radiation damage is investigated by means of Moessbauer spectroscopy, hysteresis loop measurements and by bending tests. The irradiation of the nanocrystalline as well as differently thermally treated amorphous samples is performed in the in-core reactor position. Moessbauer experiments reveal that neutron irradiation leads to partial re-amorphization in the investigated nanocrystalline alloys. For all samples it is found that the deterioration of the soft magnetic properties occurs predominantly in the higher fluence range (10{sup 18}--10{sup 19} n{sub th}{center_dot}cm{sup {minus}2}). However, this deterioration is less significant in the noncrystalline samples. The results of the bending tests show that all samples thermally embrittled below the crystallization temperature (still amorphous) can regain the complete ductility after neutron irradiation. On the other hand, the level of embrittlement of the nanocrystalline samples remained the same even after irradiation to the fluence of 1 {times} 10{sup 19}n{sub th}{center_dot}cm{sup {minus}2}.
