conclusions
Conclusions

Our first conclusion is that the relative Standardization method employed, based

on Certified Reference Materials (also a Stainless Steel material) and on a

certified radioactive Sources (for calibrating the -ray spectrometer), assures a

good analytical performance in establishing the elemental composition of an

unknown material.

Limitations:In our case, as the nuclear reactor TRIGA is located quite far from

Bucharest, the performance of our Laboratory is limited to elements that generate

by neutron activation radionuclides emitting delayed gamma-rays (with T½ 2 h).

One may also appreciate that implementation of the Quality Management System

according to the Standard ISO/IEC 17025:2000 is a very helpful tool in assuring

valid results, but it must be often demonstrated by participation in ILC/PT exercises.

However, one has to be aware that participation in any ILC /PT exercises pretends time and money.
