A procedure is described for neutron activation analysis of chlorine in zirconium and zirconium alloys. Calculation of chlorine
concentration is performed relative to zirconium concentration in the matrix in order to minimize effects of differences in
irradiation and counting geometry. Principles of the method, and the results obtained are discussed.
A radiochemical procedure developed by the authors for neutron activation analysis of As, Cd, Cu, Sn, and Zn in beef extract
samples is described, based on combined precipitation steps to isolate the elements to be determined. Nuclides are separated
with high degree of purity and good chemical yields. Interferences from threshold reactions are discussed and calculated.
Results are shown for analysis of six samples.
