Study on the Separation of ^132Te From Fission Products by Precipitation

In order to measure precisely the decay data of ^132I, radiochemical purity ^132I is directly or indirectly separated and prepared from fission products of ^235U. The source of ^132I which is separated directly has some isotope nuclides such as ^131I, ^133I, ^135I etc. that interfere measurement of ^132I by HPGe γ detector. The method of ^132I separated indirectly has two steps: 1) Its mother nuclide ^132Te is separated from fission products; 2) ^132I is separated from ^132Te. By this method, the interference of other isotope nuclides of ^132I is greatly decreased and even eliminated.
