A search for internal isotopic tracers in metallurgical materials

On the basis of the results obtained it can be concluded that none of the examined elements could be used as internal tracer for studying processes, which take place during production of steel in chosen steel-works. However, some of the examined elements could be used as inactive tracers. The results of the determination of lanthanum are particularly interesting in view of the fact that this element was used as inactive tracer for examination of the origin of exogenic inclusions.
