Transfer factors (TFs) are widely used tools for assessing the uptake of radionuclides by plants. The literature contains numerous studies on TFs in tropical and temperate climates; however, existing data arid semi-arid climates very scarce. Furthermore, current trend nuclear energy expansion countries with this type climate necessitates knowledge mechanisms radionuclide incorporation plants as well TF values. For reason, work investigates 238U 226Ra a study area during summer period under conditions equivalent to climate. selected were Scolymus hispanicus L., Eryngium campestre Chenopodium vulvaria album which collected vicinity waste dump from an abandoned copper mine. has levels above global average, addition heavy metals, it is range transfer varied between 1.5 × 10−4 kg−1 7.8 10−3 kg−1, while 226Ra, was 1.8 4.0 10−2 kg−1. correlations found PCA (i) Fe Al, (ii) S, Ti, Ca, Sr. A model created using multiple linear regression analysis. showed how related presence Fe, Ti. results obtained have allowed us propose taking into account chemical composition soil. indicate that both L. could be utilized phytoremediation soils contaminated natural climates. TFs, proposed model, allow expand absorption regions climates, necessary radiological risk assessment future fuel cycle facilities.
