摘要：

The present work is directed to characterize the phosphogypsum (PG) wastes by means of in situ atmospheric radon measurements, gross-alpha and gamma-ray spectrometry measurements. The average radon concentrations in three locations: Valea Calugareasca, Navodari and Turnu Magurele are 21.88 +/- A 3.19, 26.56 +/- A 2.90 and 33.43 +/- A 3.64 (Bq x m(-3)), respectively. The gamma-ray measurements showed that the total activities are 1510.62 +/- A 148.08, 1838.77 +/- A 165.04, 1363.83 +/- A 147.96 (Bq x kg(-1)). The results shows in all cases elevated levels of radon and Ra-226 for PG samples, indicating the necessity to find suitable routes to reduce its radiation impact on the surrounding environment.
