a reconnaissance study has been made on the distribution of 238u, 232th, 40k, 137cs andgeochemical features in soil and sediment samples at various locations on the coast of bushehr in the persiangulf. in this study a gamma-ray spectrometer based on a high purity germanium detector and a pc basedmca and x-ray fluorescence (xrf) method were used. estimation of the measured radionuclide contentha...

Medicinal plants are very useful for humans with the various molecules and vitamins they contain. Most of that grow spontaneously in nature were taken into agricultural production practices after their healing properties discovered. The use pure active ingredients obtained from is quite common. These effective compounds also used by pharmaceutical industry preparation modern drug formulations. ...

Uncontrolled disposal of oilfield produced water in the surrounding environment could lead to soil contamination by naturally occurring radioactive materials (NORM). Large volumes become highly contaminated with radium isotopes (226Ra and 228Ra). The concentration radionuclides 226Ra, 232Th 40K were determined using gamma ray spectrometry order assess radiological health hazards excess lifetime...

Natural radioactivity measurements were held in the beach sands of two main gulfs (Gera, Kalloni) Lesvos Island, Greece. These host thermal springs and are preferred tourist destinations throughout year. Dose rates concentrations natural (232Th series, 226Ra 40K) 137Cs measured in-situ laboratory by means gamma ray spectroscopy. Ten sand samples collected from each gulf. The measurement dose ra...

As part of a regional baseline study, the distribution naturally occurring radioactive materials in marine fish diversity consumed by different age group representatives living Kalpakkam coastal zone was studied. The average activity natural radionuclide 238U, 232Th, and 40K (n = 40) 28.51, 239.58, 118.95 Bq kg-1, respectively. annual dose ingestion, lifetime carcinogenic risk assessment cancer...

background: the concentrations and distributions of natural and anthropogenic radioactive materials in soils of the site of rooppur nuclear power plant (rnpp) were investigated with the aim of evaluating the environmental radioactivity and radiation hazard. materials and methods: soil samples were collected from 40 locations in and around the proposed site of rooppur power plant and determined ...

Transfer of metals from soil to plant is an important pathway human exposure environmental contaminants. In this study accumulation different was investigated and natural radioactivity levels were measured in the soil–thyme system. Results showed that concentration Br, Cr, Mn, Ni, Pb higher than World average value, P, Ca, Zn have transfer factors. The level soils similar average. For thyme sam...

The concentrations of natural (226Ra, 232Th, 40K) and anthropogenic (137Cs) in Western Coastal South Sulawesi were measured by gamma-ray spectrometry with a high-purity germanium (HPGe) detector connected to multichannel analyzer. maximum activity concentration radionuclides was found 47.29 ± 4.14 Bq/kg for226Ra, 52.73 5.28 for232Th 744.00 29.45 for40K. In general, the radioactivity marine sedi...
