Determination of Vanadium in Geological Samples of Complex Elemental Composition by X-Ray Radiometric and Neutron Activation Methods
The possibility of x-ray radiometric and neutron activation determination of vanadium in rocks of complex elemental composition is considered. Determination of vanadium by x-ray radiometric method was carried out using two sources of 55Fe activity of 100 Cu; measurement of the characteristic radiation of vanadium was carried out by a semiconductor Si(Li) detector. Neutron activation determination of vanadium was performed using installations based on 124Sb-Be and 252Cf radionuclide neutron sources. The induced activity of vanadium was measured using semiconductor Ge(Li) and scintillation NaI(Tl) detectors. The detection limit of vanadium by x-ray radiometric and neutron activation methods was 0,001 % and 0,005 %, respectively.
