Nuclear power and modern agriculture are two crucial sectors for sustainable development in the United Arab Emirates (UAE). As these industries mature rapidly country, their long-term inter-compatibility needs monitoring with local data on transfer of radionuclides from arid sandy soils to farm products. Date palms, main crop Arabian Peninsula, remain largely unstudied radioecological impact as...
Knowledge of distribution and emission pattern natural artificial radioactive elements their radiation level in the environment is very important to assess its effects on human health living organisms. In this study, specific activity for 30 soil sediment samples collected from upstream outlet Qarasu River Gorgan Bay as well sediments eastern part were measured using High-Purity Germanium detec...
Background: Presently, the British-American Tobacco Company (BAT) located in Ibadan, Oyo State is the only tobacco producing company in Nigeria accounting for about nine different brands of cigarette tobacco smoked in the country. The tobacco leaves are produced from some farmlands located in Oke-Ogun area of Ibadan where special fertilizers are used for the growing of the tobacco leav...
In this study, the specific activity of natural and artificial radioactive elements was measured for 50 sediment samples collected from throughout Miankaleh wetland in northern Iran on southeastern side Caspian Sea using a High-Purity Germanium detector. Also, radiological parameters hazard indicators due to environmental gamma radiation caused by these nuclei were calculated distribution map R...
Wheat is one of the world’s most commonly consumed cereal grains. It originates from a type grass (Triticum) that grown in countless varieties worldwide. Bread wheat or common primary species. Several other closely related species include durum, spelt, emmer, einkorn, and Khorasan wheat. In addition to being major source starch energy, also provides substantial amounts number components which a...
Measurements of 238U, 232Th, and 40K activity concentrations in some commonly used medicinal plant parts have been performed for radiation hazard assessment as baseline data health risk monitoring South Africa other countries. The mean was found to be 43.3 Bqkg-1, 33.7 180 Bqkg-1 Sclerocarya birrea; 85.0 75.3 316.7 Cymbopogon citratus; 47.3 37.0 773.3 Neorautanenia ficifolia; 25.7 30.0 510 Kige...
Background: This study aimed to investigate the radiation hazard indices from sand samples of Ma’rib Governorate in Yemen, where majority oil and gas facilities are installed. Methods Materials: Thirty five desert Yemen were collected tested their by using High Purity Germanium (HPGe) detector. Results: Based on measurement concentrations 226Ra, 232Th, 40K, radium equivalent activity (Raeq), co...
The underwater gamma-ray spectrometer KATERINA was calibrated in a special tank and then demonstrated the Southern Caspian Sea to determine radioactivity levels seawater as well sediment. simulated marine efficiency of situ detection system validated analyzing high energetic (1764 keV 214Bi 2614 208Tl) peaks using their known activity concentration determined from low energy emissions. analysis...
