Description
The radionuclide 139Ce is widely used as a component of calibration multisources. In our laboratory preparation of high purity carrier-free 139Ce was worked out. The thick target yield of 139Ce produced by bombardment of 139La with 13 MeV deuterons was found to be 159 kBq/μAh. The product 139Ce was separated from macroquantities of lanthanum by extraction with diethyl ether (DEE) in the system DEE-HNO3. The optimum conditions of 139Ce isolation were determined. (author)
