Document Summary
Experiment date: mar 13th 2015. Submission date: apr 10th 2015. In this experiment, the 137cs(parent) are decayed to make 137ba(daughter). The separation of daughter and parent were separated and measured for daughter decay and parent growth. Since ba has a very short half- life, the separation of radioactive material required speed and efficiency of performing the procedure. Often times, it is necessary to separate one element from a sample containing multiple elements in nuclear chemistry experiments. The basic method of purification of radioactive samples is similar to analytical and inorganic chemistry [1]. However, there are few differences that are required only in purifying the radioactive materials. The chemical purity of the sample is not as important as the radiochemical purity. Also, the speed is more important than a high chemical yield or even great radiochemical purity [1]. This is due to some samples with very short half- life.
