The gamma absorbed rate and annual effective dose equivalent were calculated so as to estimate the hazard index of the primordial radionuclides. Measured concentrations of radionuclides in Ewekoro cement factory soils were as follow: [238U {1.60±1.60 Bqkgapplication/pdfQ Science (General), QC PhysicsArticle
