Separation of 138Cs from fission products by a cold trap
Short-lived 138Cs can be separated from fission products by starting the separation from its parent nuclide 138Xe.A setup with freezing cold trap was developed to separate inert gas nuclides.The theory is based on that dif-ferent gases have different saturated vapor pressures.With gas-jet recoil transportation technology
the setup has been applied successfully in the separation of 138Cs from complicated fission products.Decontamination factors of main γ-emitters are higher than 104 and no other contaminators such as Kr
