| Popis: | The applicability of a radon emanation system to radium determination in fine-grained solid samples has been investigated by means of a closed radon emanation system consisting of a radon monitor and an aluminium vessel. The system has been calibrated with radium-containing fine-grained samples (e.g. phosphogypsum, granite and pitchblende) and the evaluation of the calibration data included linearity, detection limits and analytical resolution of the method. The studied radon emanation system presents very good linear response (R 2 = 0.99) to the radium content of the samples, the detection limit for radon is 25 Bq m-3 and the analytical resolution 15 Bq m -3. In addition, the relation between particle size of the materials and radon emanation has indicated that the applicability of the radon emanation system to radium determination is strongly depended not only on the mineral type but also on the particle size of the grained material. © 2013 Akadémiai Kiadó, Budapest, Hungary. 298 1 673 677 Cited By :4 |
