Determination of aluminium and sodium in tungsten by non-destructive activation analysis.
The sodium and aluminium content of tungsten has been measured by thermal neutron activation analysis. The concentration of aluminium was evaluated from the 1.78 MeV, and that of sodium from the 2.76 MeV full energy peaks. The minimum detectable concentrations of impurities were 0.04 microg of aluminium and 0.07 microg of sodium per 100 mg of tungsten.
