The research aims to evaluate the radioactivity of samples foodstuffs Consumables in local markets thirteen items were selected which are rice, tea, drinking water, lentils, chickpeas, flour, red bean, crushed chickpeas and milk powder where concentrations specific activity chains uranium (238U), thorium (232Th) potassium (40K) measured using a gamma ray spectra analysis system with high purity...

The present study was carried out on commercial types of Aswan granite used as building and decorative materials. Nearly 29 granitic rocks samples from 11 classes (black Aswan, red dark Rosa, light yellow Verdi, grey Shirka, Gandolla, Forsan, Nefertiti, Royal, white Halayeb) were collected three stations near city for petrographical description assessment natural radioactivity. granites conduct...

The concentration of anthropogenic 137Cs and naturally occurring 226Ra, 232Th 40K radionuclides were measured in the undisturbed soil at 0-5 cm depth water collected from natural reservoir Terrene Goainghat Jaintapur area Sylhet district Bangladesh near Indian border by gamma ray spectrometry, with aim evaluating environmental radiation hazard. activity was observed all samples, ranging 5.22 4 ...

Heavy duty unmanned aerial vehicles (UAVs) have made it possible to fly with large gamma-ray spectrometers that weigh several kilograms. Moreover, they can be purchased at an affordable price. These UAV-borne detection systems are used map the naturally occurring radionuclides 40K, 238U, 232Th. Such platforms advantage deployed over terrain is difficult access, while still maintaining a high sp...

Fly bioash (FBA) as a by-product of biomass-fuelled facilities exhibits alkaline properties and is enriched with phytonutrients, thereby offering the potential to effectively ameliorate acidic nutrient-deficient soils. However, concerns about health risks due FBA radioactive contamination are still not well studied, notably under field conditions. This study examined pH changes concentrations n...

background: a study on the migration characteristics of 238u, 210po, 232th and 40k within the soil to the wild plants in the western ghats were carried out. materials and methods: concentrations of these radionuclides were measured in different depths of soil and from different species by employing gamma ray spectrometer and alpha counter. results: the activity concentration of these radionucli...

Background: Naturally occurring radioactivity is a root cause of human exposure to harmful radiation. The occupational exposure hazard due to natural radionuclides occurring in drilling wastes is especially important in this regard. In this study the concentration of radionuclides namely 232Th, 226Ra and 40K were assessed in soil samples that were taken from various oil drilling areas. Methodol...

There are many regulations related to the radiological control of NORMs (Naturally Occurring Radioactive Materials) in activities such as mining, industry, etc. Consequently, it is necessary apply fast and accurate methods measure activity concentrations long-lived natural radionuclides (e.g., 238U, 234,232,230,228Th, 228,226Ra, 210Pb, 210Po, 40K) samples characterized by a wide variety composi...

Background: The activity concentrations of natural radionuclides in soil around a coal-fired thermal power plant of northwest China were investigated for assessing the radioactivity level. Materials and Methods: Soil samples were collected around the coal-fired thermal power plant and their radioactivity levels were determined using gamma ray spectrometry. Radiation hazards were assessed by rad...
