Abstract  

Energy dispersive X-ray fluorescence spectrometry with radionuclide excitation has been applied to determine As, Cu, Fe, Pb, Rb, Sr, Ti, Zn and Zr in inorganic pollutants of gravitation dust sediments. Application of this technique required a complete optimization including sampling and their preparation for analysis and evaluation. This method has been finally used to analyze series of samples of dust sediments.

Abstract  

Open-cell polyurethane foam cylinders have been used for collecting radioiodine in the vent of a labelled compound producing plant. The cylinders were unimpregnated or impregnated with Alamine 336 with or without stable elemental iodine dissolved. A collection efficiency of about 90% has been obtained for impregnated foam cylinders.
