The thesis aims at finding suitable alpha spectrometry measurement procedure and
validating it to be implemented in the laboratory where it can be used for routine
analytical procedure for the determination of 210Po in environmental samples. In
establishing if the procedure is fit for the intended purpose, the following validation
parameters were determined: trueness, accuracy (En-value, z-score), relative bias, and
tracer recovery. Also the main sources of uncertainty and their percentage contributions
were established.
