Abstract  

The indicator radionuclide31Si produced in neutron and deuteron activation analysis for silicon via the reactions30Si(n,) and30Si(d,p), respectively, is specifically separated from the irradiated sample by distillation as31SiF4. In the case of aluminium, the distillation is carried out from a HF(HNO3)H2O2 medium and in the case of molybdenum, niobium, tantalum, titanium and vanadium from a HF/HNO3/HBr/H2SO4 medium. Using liquid scintillation counting, the achievable detection limits for neutron activation analysis are, depending on the type of the matrix, between 4–50 ng/g, and for the deuteron activation analysis of tantalum the detection limit is 5 ng/g.
