Abstract: | A non-destructive neutron activation method was developed for the determination of silver and antimony in high-purity bismuth ; γ,γ-coincidence counting of 110mAg or 124Sb was applied. The activity of the matrix or other impurities did not interfere. When 1-g samples were irradiated at a neutron flux of 4·1011 n cm-2 sec-1 for 25 days, the sensitivity of the method was in the p.p.b. region. |
