“…Naturally occurring radionuclides have not been studied to the same extent as their artificial counterparts, but some comprehensive investigations have been carried out in various parts of the world. Many studies have been carried out to determine TFs for most important agricultural products (Nisbet and Woodman 2000;Ng et al 1982;Muck 1997;Masconzoni 1989;MartinezAguirre 1996;Livens et al 1991;IUR 1992;Jacobson and Overstreet 1998;Deb et al 2004;Frissel et al 1990Frissel et al , 2002Pulhani et al 2005;Popplewell et al 1984;Pietrazak-flis and Suplinska 1995;Mollah et al 1998Mollah et al , 2004Mollah and Begum 2001). Several projects were run by the International Atomic Energy Agency (IAEA) to determine TF mainly for 90 Sr and 137 Cs (IAEA 2010).…”

The entry of trace contaminants, which are present in the terrestrial environment, into human food chains is controlled in the long term by their uptake by plant roots. The radionuclides released into the environment can give rise to human exposure by the transport through the atmosphere, through aquatic systems, or through soil subcompartments. Soil-to-plant factor is one of the important parameters to be used in transfer models for predicting the concentration of radionuclides in crops/plants and for estimating dose impacts to man. Existing databases are limited to experimental values in a restricted number of soil systems and are largely comprised of temperate environment data. In general, transfer factors show a large degree of variation dependent upon several factors such as soil type, species of plants, and other environmental conditions. Soil-to-plant transfers of the radionuclides varied considerably with the times of deposition also. In general, the variations with the deposition times were by a factor of up to 10. This chapter describes a review of published data on the transfer factor (TF) and classification of soils based on TFs.

“…(Massas et al, 2010) Onion is supposed to be a good accumulator of Radiocesium its Transfer Factor is 2.87 (KBq/Kg Dry Weight of plant)/(kBq/kg Dry Weight of soil) ((Urban and Bystrzejewska-Piotrowska, 2003) as compared with other plants that are supposed to be having less TF i.e. (Mollah et al, 1998) below 1 sometimes. Therefore onion has been proposed as good phytoremediator in case of radiocesium.…”

“…Vegetation may be the subject to direct or indirect contamination [17]. Absorption of radionuclide from soils into plants is usually quantified in terms of the transfer (or concentration) factor, which is defined as the ratio of the radioactivity per unit dry weight of plant to the radioactivity per dry weight of soil in the rooting zone [18]. Transfer factor (TF) is defined as the ratio of radionuclide concentrations in vegetation and soil.…”

The paper presents results of radon ( 222 Rn) and thoron ( 220 Rn) levels in different parts of some selected plants used in Moroccan cooking and traditional medicine. Plant uptake of radionuclide is one of many vectors for introduction of contaminants into the human food chain. Thus, it is critical to understand the soil-plant relationships that control nuclide bioavailability. The radon and thoron concentrations have been determined in the studied samples and their corresponding soils, and that using the technique based on two types of solid state nuclear track detectors ( Rn from soil to parts of various studied plants have been determined. TF for roots were higher than those for stems and leaves. The radon and thoron activities in the soils have been found varying from 0.87 ± 0.06Bq.kg -1 to 6.20 ± 0.47Bq.kg -1 and from 30 ± 2.30mBq.kg -1 to 195±16mBq.kg -1, respectively. These values are lower in the leaves and stems than those determined in the roots of the studied plants. The aim of this study was to analyze the radon transfer from soil to different compartments of these plants and then to evaluate the radiotoxicity caused by radon in order to contribute to the health risk assessment.
