Radioecological researches of conifers

The spatial distribution of total specific radioactivity and natural and artificial radionuclides' content in needles of the Siberian fir and Scotch pine, growing in the central part of the Kola Peninsula has been considered. The tendency to accumulation of radioactivity in two-year needles of the explored tree species has been established. The authors have suggested that the fir needle contain a lot of radionuclides in comparison with the pine needle. The obtained data are at the level of background values, however it is possible to suppose that the fluctuations of these radiation factors can exert influence on the physiological and biochemical status of coniferous trees.
