Abstract. The release of legacy contaminants such as fallout radionuclides (FRNs) in response to glacier retreat is a process that has received relatively little attention date, yet may have consequences source secondary contamination glaciers melt and down-waste warming climate. presence FRNs glacier-fed catchments poorly understood comparison other contaminants, there now emerging evidence fr...

The aims of this study were to assess the potential radioactive contamination of fodder in the case of accidental radionuclide fallout, and to analyse the relationship between interception and retention of radionuclides as a function of biomass and Leaf Area Index (LAI). The interception and the retention of wet deposited (134)Cs and (85)Sr in ley (a mixture of grass and clover) were measured a...

Background: An amount of artificial radionuclide has been released into the environment as fallout, resulting from atmospheric nuclear weapon tests, nuclear accidents such as Chernobyl and together with air currents have polluted the world. Materials and Methods: 37 surface soil samples of Tehran province were collected in the period between June and September 2008, by implementing met...

The results of the retrospective global radioactive contamination mapping of the Enisey-river catchment are presented. The maps of spatial , J 7 Cs distributions of 1964, 1974, 1986, 2000 are compiled using the geoinformation technologies in the Institute of Global Climate and Ecology. The territory of mapping is 2600000 km. The mapping is done from the airbome-gamma-spectrum data obtained at t...
