Abstract

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.
