Determination of 226Ra, 232Th, 40K, 235U and 238U activity concentration and public dose assessment in soil samples from bauxite core deposits in Western Cameroon
Determination of activity concentrations in twenty five (25) soil samples collected from various points in bauxite ore deposit in Menoua Division in Western of Cameroon was done using gamma spectrometry based Broad Energy Germanium (BEGe6530) detector. The average terrestrial radionuclides of (40)K, (226)Ra, (232)Th, (235)U and (238)U were measured as 671 ± 272, 125 ± 58, 157 ± 67, 6 ± 3 and 99...
متن کاملAssessment of geogenic natural radionuclide contents of soil samples collected from Ogun State, South western, Nigeria
Background: Natural radionuclides are always present in the environment. Human exposure to the background radiation is inevitable. It is therefore important to assess health risk associated with these radionuclides. Materials and Methods: The distribution of natural radionuclides 238U, 232Th and 40K in soil samples collected from all the twenty (20) local Governments headquarter areas in Ogun s...

15 صفحه اولRadiological Risk Assessment in Soil Samples of Western Haryana, India
The measurements of Ra, Th and K using gamma spectrometry and radon concentration and exhalation rates measurements using solid state nuclear track (LR-115, Type-II plastic) detectors are used to asses a first order exposure risk for the persons residing in Fatehbad and Hissar districts of Western Haryana, India. The concentration of Radium, Thorium and Potassium in the soil samples varies from...
متن کاملRole of Mineralogy and Geochemistry in the Beneficiation of Jajarm Bauxite from North East Iran: Comparison with some other Bauxite Deposits of the World
Two types of bauxite occur in the Jajarm Bauxite deposit, the first one is the hard bauxite and the other is the shaly bauxite or soft bauxite. The Al 2 O 3 content ranges from 30% to 60% and SiO 2 varies between 5% to 39%.The total tonnage is more than 22 million tons with a mean value of Al 2 O 3 content between 47% to 48% , SiO 2 around 10% and Fe 2 O 3 ranges between 6.95 to 27% . The Jajar...
