Abstract:The radiochemical purity of a 131 Cs solution used in brachytherapy is studied. After separating 131 Cs from the neutron irradiated targets BaO, Ba(NO 3 ) 2 , and BaCO 3 , the contribution of impurities was evaluated: 0.015% for 124 Sb and 0.012% for 132 Cs. The contribution of the parent 131 Ba to cesium solutions was, on average, 0.0067% for BaO, 0.01% for Ba(NO 3 ) 2 , and 0.011% for BaCO 3 .Brachytherapeutic treatment methods for cancer are widely used in nuclear medicine. The essence of brachytherapy lie… Show more
