Fluorine determination in biological and environmental samples with INAA using fast neutrons from a p(19 MeV) + Be neutron generator
Original language description
We present a new activation method based on the F-19(n,2n)F-18 reaction using fast neutrons produced by a p(19 MeV) + Be accelerator-driven fast neutron source providing continuous neutron spectrum up to 17 MeV with a neutron fluence rate of approximately 9 x 10(10) cm(-2) s(-1) at a 12-mu A proton beam current. We describe elimination of interferences in measurement of F-18, a pure positron emitter with T-1/2 = 1.83 h. We present results of fluorine determination for several biological and environmental reference materials with the new procedure and compare them with those achieved by other methods in terms of limits of detection, accuracy and precision, where available.
