Optimization of surveillance methods of water radionuclide intake by man

A method has been suggested to test and sample prepared food stuffs, when studying and analyzing the intake of radionuclides from aqueous food chains to people. The method is characterized by the following advantages: a possibility to establish to a greater accuracy the amount of consumed products, as compared with inquiry method; a possibility to determine the actual radionuclide contents in prepared food without introduction of correcting coefficients for isotope translocation to the ration during culinary treatment of raw food stuff. Different ways of preparation are known to affect differently the degree of isotope translocaton to the ration. The above-mentioned method under certain conditions seems to be handy while excluding preliminary treatment of samples
