IMPROVEMENT OF THE STATE OF THE ART IN NEUTRON ACTIVATION ANALYSIS

Objective



Neutron activation analysis (NAA) is performed in the Community in approx. 30 institutes (400-3000 analyses/year each). The sensitivity and potential accuracy of NAA make it a powerful tool in a variety of applications such as:
- trace element determinations in medicine (approx. 30 % of the analyses)
- trace element determinations in environment, geology, archeology (approx. 20 % of the analyses)
NAA is frequently used in the certification of BCR reference materials. Whereas the availability of modern equipment should allow further improvement, difficulties were encountered for several elements including Cr, Se, V and Zn.
It is therefore planned to undertake a systematic study of the various causes of error, starting with Cr, Se and V.

STATUS

A detailed study of the causes of substantial errors in the analyses is in progress.
