Abstract: By Electron Paramagnet Resonance (EPR) method was studied many plants growing in Lankaran. EPR spectra of samples have recorded. Signals of ferrous magnetic nanoparticles were found in EPR spectra of most of these samples (80%). Angular variations were recorded in EPR spectra. Temperature and frequency dependence of magnetic properties of iron oxide magnetic nanoparticles was studied. When the temperature dependence of EPR spectra of the investigated plants was studied, abnormalities were observed at 120-125 K temperatures characteristic for Vervey transition phase in magnetite. The radionuclide content and elemental analysis of the studied plant and soil samples were determined.
