Distribution of cesium-137 in peat soil of a high-bog depending on the microrelief

Abstract

Spatial heterogeneity of the distribution of cesium-137 in the upper part of the peat soil profile of the high-bog Sodrinskoe (Mshinskoe swamp nature preserve, Leningrad region, RF) has been established. The horizontal distribution of cesium-137 is significantly influenced by the surface microrelief. Concentration of radionuclide depends on whether the sample was taken in a hollow or from a nearby bump.

“…Besides, the specified forest ecosystem is located near a swampy area of the forest, where in the conditions of peaty-gley soil the specific activity of fungi fruiting bodies exceeds permissible values. It should be noted that in the area of research the specific activity of cesium-137 in peat soils is distributed unevenly and in a number of cases exceeds the permissible values [6]. The results of the measurement of specific activity in the upper part of the profile of sodpodzolic soil are given in table 1 and graphically presented in figure 9.…”
