Characterization of deep sea sediments by INAA for radioactive waste management purposes

摘要: An instrumental neutron activation analysis method, using both reactor flux and epi-cadmium neutrons, has been developed for the determination of major, minor trace elements in sub-seabed sediments. The method involves two different irradiations followed by three counting periods high-resolution Ge(Li) low-energy photon detectors. list determined includes Ag, Al, As, Ba, Br, Ca, Ce, Cl, Co, Cr, Cs, Dy, Eu, Fe, Ga, Gd, Hf, Hg, I, In, K, La, Lu, Mg, Mn, Mo, Na, Nd, Ni, Pt, Rb, Re, Rh, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Th, Ti, Tm, U, V. W, Yb, Zn, Zr. accuracy evaluated analyzing four standard reference materials. applied to core samples collected from Great Meteor East South Nares Abyssal Plain which are being as potential sites possible disposal vitrified highly active waste.
