This paper describes a method for digestion of biological samples such as milk and milk products, paper filters, different seeds and meat. These samples were divided into common groups on the basis of close structure or properties. The evaluation of this method was conducted by automatic TDCR Liquid Scintillation Counter Hidex 300 SL. The alpha tracer Cm was used for the assessment of efficiency. The decomposition of samples was realized by MWS4 Speedwave (Berghof, Germany) with the method determined to be simple, safe and very effective as evidenced by high chemical yield.

    Liquid scintillation counting of the alpha-radionuclides after pre-concentration by cation-exchange represents a simple and robust method for the determination of total alpha-radioactivity in seawater. The total efficiency and the minimum detectable activity were calculated to be 95% and 30 mBq,...
