Popis:	An epithermal neutron activation analysis (ENAA) scheme involving a single-step bromide precipitation coupled with Ge(Li) spectrometry has been developed for determining trace amounts of Br in silicate rocks. The precision (2 sigma) of the method estimated from replicate analyses of rock standards is within +-10% for concentrations of Br exceeding 0.1 ppM. The observed values for Br in W-1 and JB-1 are very close to the reported values in literature. Commercial grade aluminum foil was used as sample container and flux monitor for Br analysis.
