The nitrogen content of 10 medicinal plant species has been determined by fast-neutron activation analysis (FNAA). Correction factors for the effects of the 16O(p, α)13N knock-on proton-induced reaction and the (n, 2n) reactions, which produce interfering positron-emitting radionuclides, have also been determined. The total relative interference from the 16O(p, α)13N and (n, 2n) reactions of K, Cl, Fe and Br was found to be 5.1-32.1% for the plant samples.
