Vertical distribution of Cs-137 and Sr-90 in Antarctic soils, and their concentration in soils, moss and lichen

In 21 places on the South Shetland Islands, that experience similar annual precipitation, the superficial concentration of Cs-137 was determined. For the determination of the distribution, samples were collected a profile of 25 cm for radiological analysis, and to determine edaphic parameters for the layer, 1 - 1.5 kg samples ware taken for radiological analysis. For the edaphic analysis, 4 cylinders of 305 ml per horizon were recollected. Samples were processed for gamma and chemical separation of Sr-90 in IF and NIR.
