Abstract  

Preliminary investigations of the specific226Ra activity in drinking waters of the Republic of Bosnia and Herzegovina have been performed. The results show that the concentrations of the samples vary between 0.90 and 1.32 pCi·l–1. According to the legal stipulations as given by The Official Bulletin of SFRY1, it can be concluded that the results are within given regulations.

Abstract  

The disintegration of realgar ore has been followed by neutron activation method in order to determine the amount of arsenic sulfide dissolved from As2S3. Interest in exploring realgar ore comes from the fact that its constituents (As2S3-72%, Sb2S3-0.4%, FeS2, Fe2O3-19.6%, SiO2-5%, Ca, Mg carbonates-3%) make it almost perfect for neutron activation analysis, because the activity is largely due to76As. It is possible to follow the effects of different chemical procedures in the disintegration by means of -spectrometry of the samples before and after chemical treatment.
