Abstract
A method of instrumental neutron activation analysis (INAA) is develop ed for the determination of platinum by the Au-199 daughter of Pt-199 in the presence of the spectral interference from the Sc-47 daughter o f Ca-47. The contributions of the Pt and Ca signals to the integral 15 7-161 keV peak were separated by calculating the number of disintegrat ions due to the Sc-47 from the signal of her parent Ca-47 at 1297.1 ke V gamma-ray. The method was used to calculate the trace concentrations of Pt in air samples, collected on filters, (C) 1998 Elsevier Science B.V.
