Popis:	A procedure is described for the determination of sodium in natural silicate minerals by pile neutron activation and counting the induced gamma radiation in the irradiated specimen without chemical processing. An integral scintillation counter set to accept all gamma -rays with energies above 2.6 Mev is used for radioactivity measurement. Precision and absolute accuracy of the method are of the order of 1 to 2%, and interference by trace elements is virtually negligible. Results are presented for the analysis of the standard granite G-1, diabase W-1, argillaceous limestone NBS 1a, and flint clay NBS 97. (auth)
