Anion exchange-precipitation procedure for the determination of Na(sup 24) in reactor effluent water

摘要

The isotope Na(sup 24) is one of the major short half-life constituents of reactor effluent water. It has a half-life of 15 hours and decays of emission of a 1.39 MeV maximum beta particle. Other radioisotopes present in reactor effluent water from which Na(sup 24) must be separated are Si(sup 31), P(sup 32), Mn(sup 56), Cu(sup 64), As(sup 76), Sr(sup 91--92), Ba(sup 139--140) and rare earths. This report describes a rapid and very simple method for the quantitative determination of Na(sup 24) in a radiochemically pure form.
