Discrepancy in the k0-values of 134Cs, 152Sm, 75Se and Experimental Implementations in k0 Standardization Techniques

Raymond Limen Njinga

Abstract:
Background and Objective: The k0-users are faced with the challenge of the accurate the k0-values of 134Cs, 152Sm and 75Se produced by (n,γ) reaction are in k0 standardization techniques. These values are used in determination of elemental concentrations via neutron activation analysis (NAA). The objective of this study was to evaluate the actual discrepancy of the k0-values of 134Cs, 152Sm and 75Se by using Certified reference materials (CRMs) for k0-users. Materials and Methods: The CRMs SMELS I and III, NIST 1633b Coal fly Ash were used. These samples were irradiated using the Nigerian Research Reactor (NIRR-1) at half-full power (15 kW) with neutron flux of 5×1011 n/cm2s for 7 h in the inner channel and evaluated following the established protocols. Results: The experimental and empirical calculated values of 134Cs, 152Sm and 75Se were compared with recommended data. The experimental k0 value of 152Sm (103 keV) showed a large deviation while 134Cs and 75Se agreed with recommended values. Conclusion: The k0 values of 134Cs and 75Se compared well with the recommended values while 152Sm showed high deviation. The discrepancy using the empirical calculation was high for all the nuclides.
