Abstract: In order to assess the potential environmental risk of phosphogypsum and to establish a future and proper pollution management plan of gyp-stacks and waste dumps resulted due to the operation of former chemical plant, several types of measurements have been made. This paper presents the atmospheric radon concentrations measurements for phosphogypsum deposits in three areas of chemical industry. The average radon concentrations [Bq/m³] presented in mentioned locations are: 21.88 ± 3.19, 26.56 ± 2.90, 33.43 ± 3.64. In addition to the results of radon measurements, gamma spectrometry analysis was performed on samples of Phosphogypsum (PG). The radionuclide activity concentrations in various PG samples collected at different places in the stacks are given for: ²²⁶Ra, ²¹⁴Pb, ²¹⁴Bi, ²³²Th, ²³⁸U+²³⁴U, ²³⁵U and others. The resulted total activities in the three places of Turnu Magurele are: 1510.62 ± 148.08, 1838.77 ± 165.04, 1363.83 ± 147.96 Bq/kg and subsequently compared with uncontaminated soil values.
