Rapid method for determination of Po isotopes in biological matter

A short review of the existing analytical procedures for determination of Po-210, showing their advantages and disadvantages, is presented. The criteria for selecting the proper method, according to the scope and type of matrix in study are summarised. The rapid method which is described here consists of total digestion, auto deposition and measurement by means of alpha spectrometry. The classical method in this very simple form as presented here is result of studying the possible interferences and validating the method. The application of this method in analyzing the Po-210 concentration in fresh water wild fish caught in some lakes in Austria is discussed. The corresponding ingestion dose to the public, due to Po-210 intake through consumption of these kinds of fish is estimated.
