<p>The current study presents the results of the chemical and the radiochemical characterization of phosphogypsum obtained from the former Wizów Chemical Plant in Poland. Phosphogypsum is a residue obtained from phosphoric acid production. Phosphogypsum mainly contains calcium sulfate dihydrate and impurities originating from the source phosphate rock, including toxic trace elements and natural radionuclides. The phosphogypsum stacks occupy a large area and are an environmental issue today. The project “Phosphogypsum Processing to Critical Raw Materials”, currently realized at the Institute of Nuclear Chemistry and Technology, focuses on the use of phosphogypsum from the Polish stacks as material to recover rare earth elements (REEs). The remaining gypsum matrix can be used as an inexpensive material in construction. The chemical and radiological characterization of the radioactive isotopes present in phosphogypsum was performed by using inductively coupled plasma mass spectrometry (ICP-MS) and the gamma spectrometry technique. The radioactivity of the Polish phosphogypsum was then compared with the radioactivity of the phosphogypsum waste present worldwide.</p>
