A revision is made of some activation-decay types in k0-NAA, aiming at the removal of (1) the inconvenience that a long-lived daughter radionuclide could in some instances only be measured after complete decay of a shorter-lived mother, and (2) the simplification that in some cases the measured gamma-ray emitted by the daughter radionuclide is not significantly contributed to by the mother. In view of this, new experimental and generalized k0's and related data [Q0, k0(m)/k0(g), etc.] for some analytically relevant activation-decay cases are presented for implementation in an updated version of the "Kayzero" software package. These cases are: 60mCo-60Co, 104mRh-104Rh, 109mPd-109Pd-109mAg, 122mSb-122Sb, 134mCs-134Cs, 199mPt-199Pt-199Au. For completeness, recent data for two additional cases are also included: 80mBr-80Br, 124m2Sb-124m1Sb.
