X-rays emitted by thallium and bismuth after neutron activation have been examined for their use in the determination of these elements. Interferences have been assessed. Thallium-204,206Tl and210Bi are employed. Detection limits are high but purely instrumental determinations are possible from 50 g per g to fractions of percent levels.
