Error in neutron activation analysis from recoil-implanted fission products from uranium in aluminum foil

抄録

Commercial aluminum foil may contain a high concentration of uranium, up to 1.4 μg/g. Samples or sample tubes in contact with aluminum foil during neutron irradiation can be contaminated with recoil-implanted fission products of ²³⁵U from uranium in the foil. This can lead to errors in the determination of Zr, Mo, La, Ce, Nd in neutron activation analysis.
