  • After preconcentration of Ra isotopes using Mn-fiber adsorption from large volume sea water,the specific activities of 224Ra,226Ra and 228Ra are measured through measuring γ-rays of their daughters by I-IPGe γ-spectrometer,The calculating formulas of specific activities of the three nuclides are derived,The sample preparation and spectrum analysis method are discussed.The advantages of this method are simple,rapid,and three nuclides can be determined simultaneously.
