Research ArticleOpen accessPotential Radiological Impacts of Phosphate Fertilizers Brands used in Southeast, NigeriaKenneth K. Agwu, Mark C. Okeji, Paschal TchokossaThe radionuclides present in phosphate fertilizers used in Southeast Nigeria were identified and their activity concentration determined to assess the potential radiological impact on the environment due to fertilizer applications in agricultural farm lands. The radioactivity concentration of 226Ra, 232Th and 40K in the fertilizer samples range from 13.22±1.83 to 87.37±8.98 Bqkg-1 for 226Ra (mean: 31.71±5.4 Bqkg-1), 0.78±0.07 to 47.65±6.05 … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 12 May 2017 · 7,480 accessesView PDFCite
