چکیده انگلیسی
The [Ba+Fe]-coprecipitation method is applied to measure gross alpha activity for radiological examination of drinking water in the laboratory. This method collects all the alpha-emitting radionuclides of interest (natural alpha emitters and transuranium elements) in a precipitate on a filter. This paper describes an investigation of sample pretreatment of the precipitate collected by the [Ba+Fe]-coprecipitation method for gross alpha activity determination. The aim of this preliminary work is to be a starting point to develop simple and rapid radiochemical procedures for specific alpha emitters (polonium, radium, thorium, uranium, plutonium and americium), in contrast to the sophisticated, expensive and time-consuming alpha spectrometry method. The sample pretreatment aspects considered include quantitative [Ba+Fe]-coprecipitation, two methods for precipitate treatment (leaching and complete destruction of the filter), and the determination of the alpha-emitting proportions present in the barium sulfate precipitate and acid solution obtained after precipitate treatment. Furthermore, a radiochemical procedure for 226Ra determination was performed and finally, the sample pretreatment proposed in this work was summarized.
