The results of measurements of 137Cs in soil profiles that were sampled in undisturbed soil in Ondo, Ekiti, and Oyo states in the southwestern area of Nigeria are presented in this paper. Samples were collected from nine soil profiles. The vertical distributions of 137Cs in the soil profiles have been determined. Cesium concentration ranged from 0.31 +/-(More)
This econometric study takes a sumulation approach to investigate the impact of external debt on economic growth in sub-Saharan African countries using a small macroeconometric model estimated for 1970-1994. An important finding was the significance of debt overhang variables in the investment equation, suggesting that mounting external debt depresses(More)
The natural background dose and the radium equivalent due to the natural radioactivity levels in rocks and sediments collected around Ikogosi warm spring, Nigeria, has been determined in this study using a highly sensitive HpGe detector. The mean activity concentration of (40)K, (226)Ra and (228)Ac were measured to be 585.50 +/- 17.40 Bq kg(-1), 66.91 +/-(More)
This study examines the qualitative and quantitative evidence relating to allocative and productive efficiency in the publicly owned Nigerian Telecommunications Limited (NITEL) in the wake of its commercialization and the deregulation in 1992. Estimates of changes in internal efficiency using total factor productivity analysis suggest a substantial(More)
