Exposure to high background radiation level in the tin mining area of Jos Plateau, Nigeria.
The present work deals with the radioactivity of samples of tin tailings collected from a mining site in Jos, Nigeria. The activity concentrations of the samples were measured using a gamma-ray spectrometer with a hyper-pure germanium detector. In situ dose rates at the site were also measured using a precalibrated survey meter. Potassium-40 was not detected in any of the studied samples. The a...
متن کاملAn evaluation of the equivalent dose due to natural radioactivity in the soil around the consolidated Tin mine in Baukuru-Jos, plateau state of Nigeria
Background: The equivalent dose in the human body due to the natural gamma-emitting radionucides (238U, 232Th and 40K) in the surface soil surrounding the Consolidated Tin mine site in Bukuru-Jos, Nigeria has been determined in this study. Materials and Methods: Measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (Canberra Series 10 plus) coupled ...
متن کاملEstimation of Annual Effective Dose Due to Ingestion of Natural Radionuclides in Cattle in Tin Mining Area of Jos Plateau, Nigeria
Contamination of land could occur during the extraction and handling of materials containing high levels of naturally occurring radionuclide materials. These radionuclides find their ways into the food chain. The activity concentrations of natural radionuclides 40K, 226Ra, and 232Th in heart, liver, kidney, lungs, spleen and beef of cattle slaughtered and consumed in a tin mining area of Jos Pl...
متن کاملRadiometric Assessment of Farm Soils and Food Crops Grown in Kuru-Jos, Nigeria
Introduction: Human activities, such as mining, result in the elevation of natural ionizing radiation in the environment. Jos-Plateau, Nigeria, including Kuru-Jos has experienced commercial tin mining in the past, and local mining is still being practiced in this area. Therefore, it is important to assess the radiation exposure due to grown crops and the farm soils in ...
متن کاملEvaluation of High Level Environmental Background Radiation Areas and its Variation in Ramsar
Introduction The exposure of human beings to ionizing radiation from natural sources is a continuing and inescapable feature of life on earth. For most individuals, this exposure exceeds that from all man-made sources combined. Materials and Methods In this study, the annual effective dose in high level environmental background radiation areas (HLEBRAs) of northern city of Ramsar in Iran was de...
