Reference measurements of low levels of 60Co in steel.

Analysis of 60Co traces in the matrix steel has recently gained in importance. This paper deals with the low-level gamma-ray spectrometry measurements that were part of a recent German survey aiming at determining the present levels of artificial radionuclides in commercial steel. Specific 60Co activities in the order of 10(-5) Bq g(-1) were measured. To show equivalence in these measurements, a comparison exercise of European underground laboratories has been carried out, additionally.

Sr/Ca mass ratio determination in bones using fast neutron activation analysis.

The Sr/Ca mass ratio in human bones reveals information regarding the diet which is of interest in archaeology. By using fast neutron activation analysis this ratio can be measured in a non-destructive manner, which is important when bones are considered too precious to allow for destructive analysis. Simulations and measurements showed that the nuclear reactions 88Sr(n, 2n)87mSr and 44Ca(n, p)44K are highly useful for the purpose.
