Abstract:This paper reported the level of exposure dosage of phosphate fertilizer and its ores in Chengdu; Analysed the ~(226)Ra content of phosphate fertilizer according to the national standard method. Ivnestigated thd variation of ~(226)Ra content in different phosphate fertilizer products in the same factory. Estimated the potential radiative pollution and simply assessed the potential environraertal impact on farmland.
Keywords:Phosphate fertilizer   exposure rate   additional dose   Radium-226   environmental impact assessment.
