nb 99

The beta radionuclides (99 Tc, 90 Sr, 55 Fe, 94 Nb, 59 Ni, 63 Ni) within the radioactive waste were chemically separated according to our previous reports [18, 19]. The recovery rates of the radionuclides were obtained by weighing and ICP-OES measurements using stable isotopes, and the resulting recovery yields were reflected in the equation of ... lumi 99 store
