چکیده

Phosphate rock, raw material used to produce fertilizers, due its composition can be a source of metals, radionuclides and other traces. The application phosphate fertilizers redistribute increase the concentrations both metals in soiland water profiles, influencing their availability subsequent transfer food chain. Knowing proportion this is essential implications it have on human animal health. This work studies sample treatment, radiochemicalseparation deposition/electrodeposition conditions for quantification polonium-210, uranium-238 uranium-234 by alpha spectrometry Uruguayan agricultural system. Both processes require optimization each type matrix, avoid self-absorption effect as well possible interference from present sample. method was verified quantifying International Atomic Energy Agency (IAEA) reference materials: IAEA-447 soil, IAEA-434 phosphogypsum, IAEA-330 spinach. These were quantified environmental matrices results compared with those obtained Inductively Coupled Plasma Mass Spectrometry (ICP-MS), showing comparable indicating that developed radiochemical separation suitable determination uranium polonium studied matrices.
