Sector № 8 Ion Exchange Separation of Cadmium and Rare Earth Elements Track Analysis of Uranium
Scientific Problem: Cadmium purification Application: Possibility of 117 m. Sn production from 116 Cd on the 116 Cd(α, 3 n)117 m. Sn reaction
Equipment that was used Microtron MT-25
Ion-exchange column Gamma spectrometer With HP Ge detector Lavsan detector
Experimental Technique • To estimate the ion exchange separation of cadmium and rare earth elements, the mixture of Cd. SO 4 with Dy. Cl 3 and Nd. Cl 3 has been irradiated at the Microtron MT-25 by the bremsstrahlung beam of 22 Me. V with the current of 5 µA during 2 h • Separation of Cd and rare earth elements by using ionexchange column filled with anion-exchange resin Amberlite (IRA-401) in the presence of 2, 5; 0, 25; 0, 02 mole/liter HCl was carried out • Activity of the irradiated mixture was measured by HPGe detector of the gamma spectrometer of FLNR, JINR with the energy resolution of 1, 5 ke. V at gamma lines of 1333 ke. V for 60 Co radionuclide • Track analysis of uranium was made in the received samples. The fission fragments produced by photons were recorded by lavsan detector (U( , f))

Track analysis of uranium Sample Number of tracks Contents of U, g/g Fe-Mn concretion (standard) 584 5 • 10 -6 Extract of rare earth elements 52 0, 45 • 10 -6 Extract of cadmium 72 0, 6 • 10 -6
Conclusion These experiments have shown a possibility of ion exchange separation of cadmium and rare earth elements for 117 m. Sn radionuclide production. The content of uranium has been determined with the help of track method in the received samples.
