AB  - The gully erosion is one of the most significant land degradation processes. Although gully erosion significantly threatens agricultural productivity and natural ecosystems, European land management strategies frequently need more reliable data on environmental conditions governing this process. This study presents a methodology that integrates remote sensing and nuclear techniques for examining gully erosion (Đokić et al., 2023). It introduces a novel approach to erosion research by employing 360-degree camera photogrammetry to characterize gullies morphometrically. The main objectives of this approach are to evaluate the applicability of unmanned aerial vehicles and terrestrial photogrammetry for modeling gullies, to study small-scale erosion processes within gullies, compare erosion intensity between adjacent gullies, and determine the most effective and cost-efficient method for monitoring gullies. A total of 39 soil samples were taken in three studied gullies. The results revealed an average soil redistribution rate of 16.2 t ha−1 yr−1 and coefficients of variation of 32%, 59%, and 91% for the gullies. The estimated erosion rate varies from a minimum of 0.1 t ha−1 yr−1 to a maximum of 34.3 t ha−1 yr−1. Soil deposition was identified at only two sampling sites, 1.1 and 2 t ha−1 yr−1. Highly detailed 3D models of the gullies were created using 360-degree photogrammetry. The micro-relief obtained through modeling proved to be an essential aspect of advanced erosion research.

AB  - The activity concentrations of natural radionuclides in soils from the area affected by uranium mining at Stara Planina Mountain in Serbia were studied and compared with the results obtained from an area with no mining activities (background area). In the affected area, the activity concentrations ranged from 1.75 to 19.2 mg kg−1 for uranium and from 1.57 to 26.9 mg kg−1 for thorium which is several-fold higher than those in the background area. The Th/U, K/U, and K/Th activity ratios were also determined and compared with data from similar studies worldwide. External gamma dose rate in the air due to uranium, thorium, and potassium at 1 m above ground level in the area affected by uranium mining was found to be 91.3 nGy h−1, i.e., about two-fold higher than that in background area. The results of this preliminary study indicate the importance of radiological evaluation of the area and implementation of remedial measures in order to prevent further dispersion of radionuclides in the environment.

AB  - Soil is the main source of continuous radiation exposure to human. It also acts as a medium of migration for transfer of radionuclides to the biological systems and hence, it is the basic indicator of radiological contamination in the environment. Radionuclides in soil take part in several biogeochemical processes that eventually determine their mobilization and availability for ecological processes. Knowledge of their distribution in soil is very important in radiation protection research because it forms a baseline for impact assessments in the environment wherever there is radioactive contamination from practices or releases from accidents. The soil radioactivity is important for the purposes of establishing baseline data for future radiation impact assessment, radiation protection and exploration. Natural environmental radioactivity and the associated external exposure due to gamma radiation depend primarily on the geological and geographical conditions, and appear at different levels in the soils of each region in the world. In addition to natural radionuclides, radiocaesium is a radiologically important contaminant of the soil environment. Radiocaesium was introduced into the atmosphere through nuclear weapons testing and nuclear accident especially that in Chernobyl. Due to its long physical half-life, high fission yield and very low migration velocity in soil environment, this radionuclide is very hazardous in the radioecological context. In many soil conditions it is readily available for uptake to plants resulting in potential contamination of the human food chain. In this chapter the characteristics of radionuclides commonly present in soil and factors influencing their distribution in soil are summarized. The results of extensive studies conducted in Serbia on spatial distribution of radionuclide activity concentrations in soil, their mutual relationships and assessments of radiation exposure of population are presented. © 2012 by Nova Science Publishers, Inc.
