Abstract
It is demonstrated that radiochemical separation in neutron activation analysis (RNAA) is usually the most effective means of optimization of the technique for many elements, if achieving the lowest detection limits and uncertainties are required. Examples are provided for low-level determination of vanadium, iodine, manganese, silicon, mercury, selenium in mostly biological materials. Further, it is also shown that RNAA is a superior tool for the low-level determination of natural radionuclides 232Th and 238U in shielding and construction materials for underground physics experiments on rare nuclear events, such as the search for neutrinoless double β-decay in SuperNEMO experiment.
