Assessment of Radionuclide Transfer from Soils to Plants and from Plants to Soils

Abstract

Plant surfaces may receive inputs of radionuclides by wet and dry deposition from the atmosphere and by direct irrigation. A proportion of this input can be lost via processes of resuspension and it is often difficult to separate those losses which are attributable to leaching during rainfall from processes of abscission, mortality and resuspension [1]. Seasonal factors have a major influence on these processes, affecting the surface area and physical characteristics of plant parts for particle capture, the degree of root uptake and translocation, and the magnitude of losses via abscission and mortality. All processes of uptake and loss from plants can be expected to be related not only to the maturity of the plant but also to the temperature, surface wetting, humidity, chemical form of the substance concerned and the physiological state of the plant.
