The determination of fluorine in fluorite ores and concentrates by isotope-source fast-neutron activation analysis

On irradiation with fast neutrons, fluorine-19 is converted to nitrogen-16 by the (n,α) reaction. The fluorine content of fluorite ores and concentrates can be simply and rapidly determined by measurement of the γ-activity of this nitrogen-16 product. No sample preparation, other than crushing and grinding, is required.
