Objective: Our goal was to introduce the differential method for the investigation of 14C in the samples of the environment that were inhomogeneous by the content of 14C and by the inhomogeneity of thermo-destruction of their components. We estimated sensitivity and reproduction of the method. Materials and methods: For the investigation of 14C we used traditional method on the basis of liquid scintillation count and applied vacuum pyrolysis for the component preparation of the forest litter in the search of radioactive graphite. Results and conclusions: We compared the results of the application of vacuum pyrolysis technology (Skripkin & Kovaliukh, 1997) for the production of benzene samples where the fractions of one and the same sample were processed together or separately. 14C is indicated systematically more by 51.5 % in the prepared separate second fraction of two ones of the samples in comparison with the joint sample of two fractions (R2 = 0.9554).Systematically, there was 14C more by 51.5 % in the prepared separate second of two fractions of the samples in comparison with the joint sample of two fractions (R2 = 0.9554).Downloads
