Jul 01, 2014#0183;#32;The average activity concentration of 40 K in the mining site was calculated to be #177; Bqkg 1 while in the living area; it was #177; Bqkg 1. Activity concentrations of radionuclides are generally higher in the mining site (Location AD) than in the normal living area (Location E) in Fig. 5. This may be due to the high density dust generated from the mining processes and other related
Dec 20, 2008#0183;#32;The concentration and distribution of natural radionuclides in marble around Igbeti marble mines, Nigeria, were measured to evaluate the environmental radioactivity and health effects which the marble samples may posses. The concentration of radionuclides was determined using gammaray spectrometry
To establish the baseline data and premining site environmental conditions, (1) the physicochemical properties of soils and (2) potential heavy metal and radionuclide pollutants in identified
Apr 12, 2019#0183;#32;The Pantheon and the Trajan''s Column in Rome are built of Carrara Marble. A famous saying of Augustus is: quot;I found Rome a city of bricks and left it a city of marblequot; (quot;Marmoream relinquo, quam latericiam accepiquot;).Many sculptures of the Renaissance (the David from Michelangelo, amongst many others) were also carved in marble blocks extracted from the Carraras quarry.

Dec 01, 2017#0183;#32;1. Introduction. Several investigations on the mobilization of natural radionuclides in soil, plant and water, as well as on the transfer between them, have been performed at different uranium mining sites around the world, as India (Mur et al., 2008), China (Chen et al., 2005), Brasil (Fernandes and Franklin, 2001, Santos et al., 2015), Nigeria (Ibrim et al., 2013), Canada, Australia
In industry, and in mining, radionuclides are used to examine welds, to detect leaks, to study the rate of wear, erosion and corrosion of metals, and for onstream analysis of a wide range of minerals and fuels.
Evaluation of Naturally Occurring Radionuclide in Soil Samples from Erena Mining Sites in Niger State, Nigeria June 2018 Current Journal of Applied Science and Technology 27(6):112
Clay soil samples collected from different sites in Ekiti State, southwestern Nigeria were analysed for their natural radionuclide contents, using the gamma ray spectrometric method. The overall mean activity concentrations of 226 Ra, 232 Th and 40 K obtained in this study were, respectively, #177;, #177; and #177; Bq kg 1. The radiological hazards incurred from the use of the clay soil as a

Therefore, it poses no radiation threat to the human population as well as other environmental elements living around these areas. Keywords: Marble, radionuclides, radiation, effective dose, hazards
The mean total of the concentration of the radionuclides in the soil samples is #177; Bq kg1, #177; Bq kg1, #177; Bq kg1, for 40K, 226Ra, 232Th respectively as shown in table2.

Radionuclide In Marble Mining Site Radionuclide contents in raw minerals and soil samples and mining sites from which the raw minerals, Limestone, Kaolin, Clay and Baryte are obtained in the state.
mining requires a logical methodology for proper assessment of the dose rate arising from the naturally occurring radionuclide. The methodology that was employed in carrying out this work includes careful collection of soil samples (of about 1 kg each) from the mining site

The soils from the mining sites were enriched in U, As and trace metals. Hot spots with elevated radioactivity levels were easily detected in Kadji Sai and radioactive particles were observed. The presence of particles carrying significant amount of radioactivity and toxic trace elements may represent a hazard during strong wind events (wind erosion).
