Study of natural radioactivity to Assess of radiation hazards from soil samples collected from Mounana in south-east of Gabon
Background: The present work aims to determine the activity concentrations of 226Ra, 233Th and 40K in soil samples collected in Mounana in the Southeastern region of Gabon, to evaluate the contribution of the natural. Materials and Methods: An HPGe p-type detector coupled with a multichannel analyzer DSA-1000 was used to perform measurements and process data. Data acquisition and analysis were ...
متن کاملMeasurement of Natural Radioactivity in Certain Types of Nut Samples in Iraq
Introduction: The present study was conducted to measure the specific activities of 226Ra,232Th and 40K, in some samples of nuts collected from the local markets in Iraq. In addition, this study sought to calculate the annual effective dose of gamma ray to children and adults. Material and Methods: The quantification of radionuclides was accomplished by gamma spectrometry NaI (Tl) detector. Res...
متن کاملMeasurements of Natural Radioactivity and Mössbauer Effect in Some Soil Samples Collected from the New Campus of Taif University, Saudi Arabia
Eleven soil samples from the new campus of Taif University and its neighboring areas, Saudi Arabia have been studied by high-resolution γ-ray spectroscopy, x-ray powder diffraction and Mössbauer spectroscopy to ascertain their overall characterization. The mean and range of the activity concentrations of 232 Th, 234 Th, 226 Ra, 40 K and 137 Cs isotopes in the soil samples are 1.68±0.2 (8.3 40.2...
متن کاملNatural radioactivity in Indian vegetation samples
Background: Vegetation (food stuff) is grown in soil that contains many radioactive elements such as 238U (uranium), 232Th (thorium) and 40K (potassium), which may get deposited either due to radioactive fallout or/and by absorption from the soil and can pose serious health hazards. Materials and Methods: Natural radioactivity, radiological hazards and annual effective dose assessment was carri...
متن کاملMeasurement of Natural Radioactivity in Coal, Soil and Water Samples Collected from Barapukuria Coal Mine in Dinajpur District of Bangladesh
The activity concentrations of naturally occurring radionuclides Ra-226, Th-232 and K-40, were measured by using a gamma ray spectrometry for coal, soil and water samples collected from the Barapukuria coal mine in Dinajpur district of Bangladesh. The average activity concentrations of Ra-226, Th-232 and K-40 in coal samples were found to be 6.21±3.68, 10.69±7.5 and 185.76±138.86 Bqkg, respecti...
