Description

225Ac is obtained in reaction 226Ra(γ,n) in electron accelerator microtron MT-25 FLYaR. Radiation yield of 225Ac in conditions studied is 550 Bq/(mcA h mg 226Ra). Purification of 225Ac from target material and radioactive impurities is carried out using ion exchange. Ratio of radioactivities 225Ac:227Ac:226Ra in preparation is 1:≅2 x 10-9:≤6 x 10-5

Abstract (Russian)

225Ac был получен в реакции 226Ra(γ,n) на ускорителе электронов - микротроне МТ-25 ФЛЯР. Радиационный выход 225Ac в условиях облучения составил 550 Бк/(мкA ч мг 226Ra). Очистку 225Ac от материала мишени и сопутствующих радиоактивных примесей проводили с применением ионного обмена. Соотношение активностей 225Ac:227Ac:226Ra в препарате равно 1:≅2 x 10-9:≤6 x 10-5
