Uptake of 137Cs in forests under low fallout levels has received little attention. Most of 137Cs is accumulated in one-year-old needles of Siberian fir. An approach was suggested to estimate 137Cs activity concentrations in soil solutions. Flow of isotope from canopy to ground was found to be smaller than global fallout. Based on 137Cs activity a method is suggested to estimate ages of soil horizons.
