Abstract
Abstract
Determining the gross alpha activity concentration of water samples is one way to screen for waters whose radionuclide content is so
high that its consumption could imply surpassing the Total Indicative Dose as defined in European Directive 98/83/EC. One of the
most commonly used methods to prepare the sources to measure gross alpha activity in water samples is desiccation. Its main advantages
are the simplicity of the procedure, the low cost of source preparation, and the possibility of simultaneously determining the gross
beta activity. The preparation of the source, the construction of the calibration curves, and the measurement procedure itself involve,
however, various factors that may introduce sufficient variability into the results to significantly affect the screening process. We
here identify the main sources of this variability, and propose specific procedures to follow in the desiccation process that will
reduce the uncertainties, and ensure that the result is indeed representative of the sum of the activities of the alpha emitters
present in the sample.
