This investigation was carried out in order to assess the marine environmental radioactive pollution and the radiological impact caused by a large production plant of phosphate fertilizer, located in the Lebanese coastal zone. Natural radionuclides ((238)U, (235)U, (232)Th, (226)Ra, (210)Po, (210)Pb, (40)K) and anthropogenic (137)Cs were measured by alpha and gamma spectrometry in seawater, sediment, biota and coastal soil samples collected from the area impacted by this industry. The limited environmental monitoring program within 2 km of the plant indicates localized contamination with radionuclides of the uranium decay chain mainly due to the transport, the storage of raw materials and the free release of phosphogypsum waste.
本研究旨在评估位于黎巴嫩沿海地区的大型磷矿肥料生产厂所造成的海洋环境放射性污染和辐射影响。通过α和γ能谱法，对受该工业影响地区的海水、沉积物、生物群和海岸土壤样本中的天然放射性核素（(238)U、(235)U、(232)Th、(226)Ra、(210)Po、(210)Pb、(40)K）和人为放射性核素（(137)Cs）进行了测量。距离工厂 2 公里范围内的有限环境监测计划表明，铀衰变链中的放射性核素主要由于原料的运输、储存和磷石膏废物的自由释放而导致局部污染。
