Abstract

Trace elements in certified iron and steel reference standard materials of NIST, SRM1763 and SRM1765 were determined by an instrumental neutron activation analysis (INAA). Three aliquot samples of each certified standard reference material (<i>ca</i>. 85-210 mg) were irradiated for 6 h at thermal power of 100 kW (thermal neutron flux of 4.3×10<sup>14</sup> n m<sup>-2</sup>s<sup>-1</sup>) and at thermal power 3.5 MW (thermal neutron flux of 5.3×10<sup>17</sup> n cm<sup>-2</sup>s<sup>-1</sup>) in JRR-4 (Japan Atomic energy Agency). The irradiated samples were measured by γ-ray spectrometry using a coaxial Ge detector. The concentration of 11 elements (Al, Ti, V, Cr, Mn, Co, Ni, Cu, As, Mo, Sb) in the SRM1763 and 9 elements in the SRM1765 were determined by INAA. The determined values were in good or nearly good agreement with the certified values and reference value.
