Abstract
In order to reduce the sample pretreatment in the measurements of γ- and β-emitter radionuclides in environmental analysis, we present the application of the microwave oven to dry different environmental macrosamples such as vegetables, milk, meat, fish, soil and sediment. We have also studied this technique to evaporate water (rain water and seawater) and to optimize acid digestion of sediments. The results show that the microwave oven gives good results for drying environmental macrosamples, for evaporating water samples when applied in acid atack. With the porposed procedures, time of analysis shortened dramatically.
