Gamma Hazards and Risk Associated with Norm in Sediment from Amang Processing Recycling Ponds
Amang processing is an important down stream activity of tin mining noted for technologically enhancing naturally occurring radioactive materials. A study was carried out to determine the gamma radiation hazards associated with amang processing with special reference to the sediment accumulated in amang processing ponds. Twenty eight sediment samples from two amang processing plants employing t...
متن کاملMeasurement of exposure to radionuclides (40-K, 226-Ra, and 232-Th) in the oil and gas drilling industry
Background: Naturally occurring radioactivity is a root cause of human exposure to harmful radiation. The occupational exposure hazard due to natural radionuclides occurring in drilling wastes is especially important in this regard. In this study the concentration of radionuclides namely 232Th, 226Ra and 40K were assessed in soil samples that were taken from various oil drilling areas. Methodol...
متن کاملAn approach to determination of 226 Ra and 228 Ra in the ground water and its impact on the population dose
The concentrations of naturally occurring radionuclides of Ra and Ra were determined in the groundwater samples in three areas near Riyadh city in Saudi Arabia. The waters of these areas are supplied for the city consumption. A total of thirty water samples of the three areas were analyzed for Ra and Ra. The concentration of Ra was found in the range from 2.1 – 6.3, 7.2 14.1 and 16.7 – 33.5 mBq...
متن کاملTracing the Amazon Component of Surface Atlantic Water Using <sup>228</sup>Ra, Salinity and Silica
High 228Ra/226Ra ctivity ratios characteristic of waters in the Amazon estuary provide a sensitive indicator of the presence of these waters in the Atlantic Ocean. A conservative mixing model utilizing the 228Ra/226Ra ctivity ratio (AR) tied to absolute measurements in the estuary allows us to estimate that 20-34% of the surface water east of the Antilles during June, 5-9% from the same area du...
متن کاملA century of oil and gas exploration in Albania: assessment of Naturally Occurring Radioactive Materials (NORMs).
The Naturally Occurring Radioactive Materials (NORMs) that are potentially generated from oil and gas extractions in Albania have been disposed of without regulations for many decades, and therefore, an extensive survey in one of the most productive regions (Vlora-Elbasan) was performed. A total of 52 gamma ray spectrometry measurements of soil, oil-sand, sludge, produced water and crude oil sa...
