Abstract :
This work aims at measurement of Pu-239 for nuclear materials safeguards verification purposes. The work was carried out at Los-Alamos National Lab, (USA). Due to the strategic nature of the element, few samples were available to be assayed. The gamma spectrometric non-destructive assay technique was used for determining amount of Pu in the samples. A correction factor for self-attenuation due to the Pu matrix was made. The results show that the declared (certified) and measured (verified) values of Pu-239 agree with an average precision of about 0.40%
