Possibility of Monte Carlo simulation for predicting radioactivity in the Baghak, NE Iran
Uranium deposits are found in various geological environments; therefore, these exist in almost all geological phases: in high degree of metamorphic, metasomatic, Metamorphism, Surficial and Volcanic to Sedimentary perimeters. In this study, the amount of uranium in the Baghak mine (as a case study) was predicted using piecewise regression and Monte Carlo simulation at a 90% confidence level. To this end, 151 geochemical samples from the study area were analyzed, with rare earth elements, thorium, and yttrium selected as independent parameters due to their highest correlation with uranium. An equation was derived for estimating uranium levels, showing a high correlation (86%) with actual data. Based on the final model, 2,200 random data points for uranium were generated, with the mean differing by only 0.1 (logarithmic unit of concentration) from actual values. This indicates the model’s high accuracy in simulating real values. The simulated values closely matched actual values based on the density function, confirming the model’s validity. In this area, the confidence interval for uranium is from 1.8 to 2.6 based on logarithmic calculations. Finally, the independent parameters were prioritized based on their impact on predicting uranium levels. This research could be considered a practical tool for assessing and predicting uranium concentrations in various regions and could aid in improving mineral resource management.
期刊介绍:
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
