The aim of this study was to demonstrate and validate the use of the absolute NAA method, inside the Malaysian nuclear agency (MNA) research reactor, by analyzing the IAEA SRMs; soil-1 and soil-7. The analytical results showed that the deviations between experimental and certified values were mostly less than 10% with Z-score ranging from 0 to 2, and only for few element it exceeds 20%. In general, the results for soil-1 and soil-7 obtained from research reactor at irradiation positions 10, 22, 27 and 31 inside the rotary rack agree reasonably well with the certified values.
Key words: Neutron activation analysis (NAA), absolute NAA method, accuracy, standard reference materials (SRMs), Z-score.
