The aim of the research was to obtain first results of tritium in the organic matter of environmental samples in the vicinity of Krško NPP. The emphasis was on the layout of suitable sampling network of crops and fruits in nearby agricultural area. Method for determination of tritium in organic matter in the form of Tissue Free Water Tritium (TFWT) and Organically Bound Tritium (OBT) has been implemented. Capabilities of the methods were tested on real environmental samples and its findings were compared to modeled activities of tritium from atmospheric releases and literature based results of TFWT and OBT.

Very special thank goes to dr Irina Vagner, dr Carmen Varlam and all other colleagues of the National Research and Development Institute for Cryogenic and Isotopic Technologies, Ramnicu Valcea, Romania for their unselfish help, assistance, support, encouragement and all advices they provide during implementation of the method to our laboratory. Authors would like to thank Mitja Centrih who helped us with the graphic presentation of results and some suggestions.
