Abstract: The radionuclide x-ray fluorescence method is an effective technique for multielement anal. of plant tissues. The simultaneous detn. of heavy metals content in above- and underground parts of plants is described. The x-ray measuring system consisted of a radionuclide source of 238Pu exciting K x-rays of Mn, Fe, Ni, Cu, Zn, as well as L x-rays of Pb, and and Si/Li semiconductor detector connected to the multichannel x-ray analyzer. All the measurements were performed in noncoaxial geometrical arrangement of source, sample, and detector.
