Extraction of the 131Cs from neutron irradiated barium oxide under microwave radiation

In this work, the solubility dependence of radioactive baric samples under influence of microwave radiation (MWR) has been investigated at various concentrations of HCl after irradiation of BaO target at a flux of thermal neutrons. It is established that the use of MWR for dissolution of a sparingly-soluble barium oxide will accelerate a dissolution process at almost an order of magnitude in comparison with usual heating. Each time after separation of the 131Cs from radioactive barium solution analyses on radionuclide purity of the 131Cs product solutions were carried out.
