Introduction: Accurately determining the k0- values of 134Cs, 152S, and 75Se produced by the (n,() reaction is a difficulty for k0 users using k0 standardization procedures. Neutron activation analysis (NAA) is performed to determine elemental concentrations using these values. This study’s goal was to assess the true gap between the k0- values of 134Cs, 152Smand 75Se utilizing K0-user certified reference materials (CRMs). Supplies and Procedures: Utilized were the CRMs SMELS I and III and NIST 1633b Coal fly Ash.These samples were exposed to radiation for seven hours in the inner channel using the Nigerian Research Reactor (NIRR-1) at half-full power (15 kW) and a neutron flux of 5×1011 n/cm2 s. The evaluation was conducted in accordance with the approved guidelines. Findings: The empirical and experimental calculations values of 152Sm, 75Se, and 134Cs were contrasted with suggested data. The experimental k0 value for 152Sm (103 keV) was significantly different from the suggested values for 134Cs and 75Se. In conclusion, 152Sm displayed a large deviation whereas the k0 values of 134Cs and 75Se contrasted favorably with the suggested values. For every nuclide, the empirical computation yielded a large discrepancy.
