“…On the other hand, natural environmental radioactivity arises mainly from primordial radionuclides, such as 40 K, and the radionuclides from the 232 Th and 238 U series and their decay products are also considered important due to their contributions to the internal radiation dose. Several studies on transfer of natural radionuclides from soil to plants have been carried out in different regions in the world (Sheppard and Evenden, 1992;Martinez-Aguirre and Perianez, 1998;Ewers et al, 2003;Staven et al, 2003;Vera Tomé et al, 2003;Pulhani et al, 2005;Blanco Rodríguez et al, 2006Al-Masri et al, 2008).…”

“…One of the key parameters in environmental assessment is the soil to plant transfer factors to food and fodder crops. Some of these studies are those related to transfer of 238 U, 232 Th and 226 Ra from uranium mining-impacted soil in southern China (Chen et al, 2005), TFs of U and 226 Ra from contaminated soil in uranium mines to Brassica Juncea (Blanco Rodríguez et al, 2006), and accumulation of 238 U, 230 Th and 226 Ra by wetland plants in the vicinity of uranium mill tailings in Zirovski vrh (Slovenia) (Ceme et al, 2010) in field conditions. Others used greenhouse conditions for transfer factor studies on soil collected from a former uranium or processing facility in south Bohemia, Czech Republic (Soudek et al, 2010).…”

“…La ecuación de la curva que describe la concentración de U en tejido vegetal en función de la concentración en el medio es del mismo tipo tanto en raíz como en parte aérea, y es equivalente a la utilizada por otros autores para relacionar las concentraciones de radiactividad del U en plantas y sustrato (Martínez-Aguirre et al, 1997;Blanco Rodríguez et al, 2006). Esta ecuación puede generalizarse como:…”

“…El girasol (Helianthus annus L.) es una de las plantas más estudiada en relación a su acumulación, tolerancia al U y potencial uso en rizofiltración (Dushenkov et al, 1997;Shahardeh y Hossner, 2002;Singh et al, 2005;Blanco Rodríguez et al, 2006). La acumulación de U en girasol se produce fundamentalmente en la raíz donde el factor de bioacumulación en relación a la concentración de U en el agua puede alcanzar a 30.000 (Dushenkov, 2003).…”
