On the basis of their complex and characteristic decay schemes, a number of radionuclides formed for example by neutron capture can be selectively detected and quantitatively determined by means of $\gamma,\gamma$-coincidence measurements. The method is specifically applied to the elements selenium ($^{75}$Se) and iridium ($^{192}$Ir). lt offers the advantage of extremely high sensitivity of detection (ca. 10$^{-10}$ gram) and permits in addition the performance of non-destructive analyses in suitable matrix materials, such as iron and platinum. Disturbances due to the presence of other $\gamma$-emitters can largely be prevented by discrete choice and adjustment of the coincidence ranges. The influence of the sample composition and dimensions are discussed. The particular advantage of the method consists in a considerable simplification and reduction of the time of chemical treatment. |
