ملخص: In recent years the k0:NAA method has been applied and developed at the 15 MW Es:Salam research reactor, which includes: (1) the detection efficiency calibration of [gamma]:spectrometer used in k0:NAA, (2) the determination of reactor neutron spectrum parameters such as [alpha] and f factors in the irradiation channel, and (3) the validation of the developed k0:NAA procedure by analysing SRM, namely AIEA:Soil7 and CRM, namely IGGE:GSV4.The analysis results obtained by k0:NAA with 27 elements of Soil:7 standard and 14 elements of GSV:4 standard were compared with certified values. The analysis results showed that the deviations between experimental and certified values were mostly less than 10%.The k0:NAA procedure established at Es:Salam research reactor has been regarded as a reliable standardization method of NAA and as available for practical applications.
