Description
The applicability of radon emanation to determine radium levels in (TE)NORM after EDTA-mediated sample dissolution has been investigated by means of a closed recirculating air loop radon monitoring system. Regarding radium determination in gypsum samples after EDTA-mediated dissolution the method presents excellent linearity (up to 2000 mBq), good resolution (75 mBq g-1) and detection limits (40 mBq g-1). The radioanalytical method presented here has been successfully applied to phosphogypsum samples and the radium levels obtained have been validated with gamma-spectroscopy. Evaluation of the experimental data indicate the robustness, selectivity and cost-effectiveness of this alternative radium analysis approach. (author)
