Results of inter-comparison test organized by the IAEA are analyzed according to the contribution and performance of INAA as non-destructive method for trace elements analysis as compared to other techniques. Several methods were employed for certifying the biological sample (IAEA-0140) and were also compared. It is shown that NAA is the method of a good accuracy and precision. The biological sample has been investigated by INAA based on semi-absolute technique. More than 30 elements have determined without using standards. The reference materials, which are certified in this manner and utilized as primary standard, are also discussed.
