Distribution of 40K, 137Cs, 226Ra, 232Th and 241Am in sloping landscapes of varying steepness observed after forest fires
Work is devoted the analysis of features of migration of radio nuclides after forest fires. The purpose of researches consisted in studying of distribution of activity of natural and artificial radio nuclides depending on character of a relief, taking into account geometry of slopes and other features of a relief. It is established that activity, as a rule, increases at bottom of slopes. As in case of the large-scale lay of land which element is the slope, and in territories of rather small bias. It is revealed that as a result of wood and meadow fires there is a change in parities of various isotopes.
