Abstract |
|
|
| In this study, Evaluation of Radon-222 Concentration Levels in Drinking Water Sources at Mararraba-Udege Quarrying and Mining Site in Nasarawa LGA, Nasarawa State, Nigeria was assessed Three (3) reading is taken at each point and the average was taken and each point were sampled, a total of fifteen samples were selected and the concentration rate were measured using a Liquid Scintillation Counter (manufactured by Packard Tri-carb LSA 1000TR)), the Liquid Scintillation Counter was held at an elevation of 1.0m above ground level, the absorbed dose rate, annual effective dose rate, were calculated, using the radiological hazard indices, the result obtained are in the range of 0.8719-0.9048 Bq/L,0.831-0.859 mSv/y, 11.040-11.413 mSv/y for CRn, Eing, and Einh respectively, the obtained values of Eing and Einh this value is higher than the permissible limit of 1.3mSv/y for inhalation and 0.1-0.2mSv/y for ingestion set by WHO (WHO, 2004). This indicates that the inhabitants around Mararraba-Udege Quarrying and Mining Site and its workers are not safe from radiation hazards, so there is a need to educate, create awareness among Mararraba-Udege Quarrying and Mining Site workers and members of the public around the mining site on the risks associated with Rodon-222 and precautions to take. |
