Gladney and Perrin [6] used epithermal neutron activation analysis to determine down to 50 ppb bromine in the US Geological Survey Reference Soils GXR-2, GXR-5 and GXR-6, and the Canadian Certified Reference Soils SO-1, SO-2, SG-3 and SO-4. The values reported in Table 6.1 indicate that good agreement was obtained between neutron activation analysis results and recommended values. The relative standard deviation was on the order of 10% over the concentration range 1-15 ppm bromine ...

The NAA technique makes use of the slow neutrons. However, the epithermal and fast neutrons may also be used for the activation. An NAA technique that employs only epithermal neutrons to induce (n, y) reactions by irradiating the samples being analyzed inside either cadmium or boron shields is called epithermal neutron activation analysis (ENAA). An NAA technique that employs nuclear reactions induced by fast neutrons is called fast neutron activation analysis (FNAA).
