Introduction: This study was conducted to measure the gamma emitters (e.g., uranium-238 [238U], thorium-232 [232Th], and potassium-40[40K]) and alpha emitters (e.g., radon-222 [222Rn] and radium), and also to evaluate the radiation hazard indices of radionuclides in parenteral nutrition samples utilized in the hospitals of Iraq. Material and Methods: The measurements were accomplished using ga...

This research aimed to assess the levels of natural radionuclides in soil Riruwai mining area and evaluate radiological hazards associated with them. A total sixty samples were collected from four sampling sites during dry wet seasons. The concentrations uranium-238 (238U), thorium-232 (232Th), potassium-40 (40K) measured using an HPGe gamma-ray spectrometer, used estimate internal external gam...

The specific activity and spatial distribution of 238U, 232Th 40K were determined in the surface soil from Lișava uranium mining sector. This sector belongs to Banat district, an historically important area Romania (an with closed mines a radioactive waste dump). Gamma-ray spectrometry using high-purity germanium (HPGe) detector was used measure naturally occurring radionuclides soil. average a...

Evaluation of Radiological Hazards associated with some selected mining sites (ie Gadaeragi (GR), Maiwayo (MW) and Kataeragi (KR)) in Niger State, Nigeria was carried out using Nal (TI) Gamma ray spectroscopy. The results shows average activity concentration for 238U, 232Th, 40K site are 8.05 ± 0.14 Bq/kg, 14.60 0.30 Bq/kg 20.62 14.62 respectively. result 232Th to be 12.03 0.17 17.89 0.32 151.1...

This study was conducted to determine and compare the activity concentration of natural radioactivity 238U, 232Th, 40K in borehole well water samples collected from Lokoja Nigeria, using Sodium Iodide−Thallium gamma spectroscopy. Samples selected wells were standard radiation protocol analyzed. The result shows that sample 2.77±0.67 Bq/l; 2.30±0.27 Bq/l 1.66±0.13 for respectively, 17.62±1.37 wh...

The occurrence of heavy radioactive minerals in construction supplies such as granite has drawn attention to the extraction minerals. Granitic rocks were identified serve an essential economic role study area’s surrounding locations. As a result, current attempted detect activity concentrations 238U, 232Th, and 40K granitic rock samples tested estimate radiological dangers associated with these...

Nesse trabalho foi utilizada a técnica da espectrometria gama de alta resolução com detector HPGe e o pacote software GENIE 2000 para determinação concentração atividade dos radionuclídeos 226Ra, 232Th 40K presente em amostras solo, risco radiológico visitantes do Núcleo Piraquara, importante Trilha Ecoturismo Parque Estadual Pedra Branca – RJ. Os resultados apresentaram concentrações atividade...
