Features of the radial wood growth in the weakened pine-bilberries of Bryansk region contaminated with radionuclides

The results of a comparative analysis of the dynamics of radial tree growth in typical ripening pine forests of the Bryansk region are given. in the zone of the accident at the Chernobyl nuclear power plant with a high (156 Ci / km2) and moderate (2.6 Ci / km2) soil contamination density of cesium-137. The oscillations of the total width of annual rings and the growth of early (spring) and late (summer) wood of trees classified as "strongly weakened" and "drying up" are considered, depending on the density of soil contamination with radionuclides.
