The use, for analysis, of prompt gamma-rays excited by 5 MeV alpha-particles from the reactions19F(α,α′γ)19F,19F(α, nγ)22Na and19F(α, pγ)22NE, was studied. The precision of the analyses depended on the gamma-ray energy used for the measurement. Relative standard
deviations were ±1.8, ±0.9 and ±1.3% using the 110-, 197- or 1275 keV gamma-rays. The method was tested with N. I. M. standard
materials of calcium fluoride and fluorspar, and was used as a rapid method for the determination of fluorine in cements.
