Background: Natural-occurring radioactive materials (NORMs) provide significant sources of human exposure to ionizing radiation but in certain cases, anthropogenic activities, like mining, have produced wastes that contain radiation above background levels in the environment, a situation that is of great concern for radiation protection. Around Dangote cement factory both mining and production have been ongoing for some years, therefore there is need to evaluate the extent of the possible risk of the radionuclides to the health of the population in this study area. Measurements of radioactivity concentrations were carried out around Dangote Cement Factory Ibese. Samples of surface soil were measured using gammaray spectroscopy Nal (TI) scintillation detector. Results: Measurements showed that activity concentrations ranged from 18.

The aim of this study is essentially to evaluate radiation doses to paediatric patients who were referred for chest X-ray examination between April, 2015 and December, 2016 in three hospitals SouthWest , Nigeria. The methodology employed in this study involved measurements based on the use of exposure parameters to determine Entrance Surface Dose (ESD). A total of one hundred (100) paediatric patients randomly chosen were included in this study. ESD was determined from exposure parameters using dose calculation software (Dosecal). The results of this study show that the range of Entrance Surface Doses (ESDs) obtained for 0-1year patient is 38.00-150.00 µGy, for 1-5 years is 43.34-194.00 µGy, for 5-10 years is 74.00-223.00 µGy and for 10-15 years is 87.60-292.00 µGy. The mean ESDs obtained in this study were found to be relatively lower than the ESDs obtained in other previous studies in Nigeria but higher than the recommended reference Original Research Article
