The need for accurate isotope abundance values (θ) in reactor neutron activation analysis is discussed. A comparison of literature θ-values for target isotopes of low abundance is made and this shows a considerable scattering of data. Although the k0 standardization method can offer some help in nuclear data evaluation, it must be concluded that, for some 14 analytically interesting minor isotopes, more reliable θ-values are required: 36S, 50Ti, 58Fe, 64Ni, 74Se, 84Sr, 112Sn, 122Sn, 124Sn, 130Ba, 162Er, 174Hf, 198Pt, 196Hg.
