The critical landscapes identification: Radioecological approach

Abstract

Abstract. A new approach to identification of radiological criticacy of landscapes in radioactive contaminated lands by estimated dependence between landscape conditions and l37 Cs soil-to-plant transfer factor (TF) was revealed. A map of TF values for meadow caenoses on abandoned agricultural lands reflected radiological criticacy of the area was built.

Root uptake of 137Cs by natural and semi-natural grasses as a function of texture and moisture of soils

“…The specific landscapes of the contaminated territories show abnormally high biogenic migration of radionuclides, which allows considering them as radioecologically critical landscapes. Thus, their criticality is caused not so much by the high levels of soil pollution, as by a set of natural conditions, which determine the intensity of radionuclide accumulation in biota (Grytsyuk, 2002).…”
