摘要

Disclosed is a neutron absorber of amorphous alloy which comprises at least one of Fe, Ni and Fe-Ni, and at least one of neutron absorbing substance such as B, Sm, Gd, Eu, Er, Dy, Rh, Re, Ir, Au, Ag, Li, Cd, In, Hg and Hf, with or without other heat stabilizing substance(s) and/or Cr. The neutron absorber can be prepared in the form of a foil, and is utilized for a neutron absorber assembly for control rod of a neuclear reactor, a neutron shielding material for clinical purpose, and a neutron absorber curtain for a waste storage tank for radioactive wastes.
