Description

A cyclic neutron activation analysis (CNAA) method for determining the vanadium content of Mongolian coals and phosphorites is described. Samples were irradiated using an experimental setup based on a Sb-Be neutron source. The choice of optimal conditions for CNAA using a 124Sb source with an activity of 2,5.1012 Bq allowed one to reach the detection limit of vanadium in coals of 5-10 ppm. The density of the thermal neutron flux in the central channel of the setup was 2.106 neutr.cm2s-1, and that of epithermal neutrons was 2.105 neutr.cm2s-1. (orig.)
