“…In a study conducted in Georgia, values ranging from 4 to 33 Bq kg −1 were determined [54]. In another study in Georgia, 137 Cs activity concentration ranged from 0 to 53 Bq kg −1 [55]. In a study conducted by Karakelle and colleagues in Turkey in 2002, it was revealed that 137 Cs levels varied between 2 and 25 Bq kg −1 [56].…”

In this study, the current status of natural and artificial radioactivity levels in soil samples from the Büyükçekmece and Silivri districts of Istanbul, as well as the Marmara Ereğlisi district in Tekirdağ, has been determined in anticipation of a potential nuclear leakage (e.g. the Zaporizhzhia Nuclear Power Plant). Twenty soil samples were collected from the study area, and the radioactivity concentrations of 226Ra, 232Th, 40K and 137Cs were measured using an HPGe detector. The average concentrations of 226Ra, 232Th, 40K and 137Cs were found to be 26 ± 2, 30 ± 2, 540 ± 29, 0.55 ± 0.07 Bq kg−1, respectively.

“…232 Th naturally exists in soil, and its activity concentration in phosphatic fertilizers is extremely small [43]; its relatively low concentration in the studied soil could be attributed to soil parent materials [12,16]. In slightly and moderately alkaline soils, 226 Ra is mostly present as an available form and easily leached by waters [44]. On the contrary, 232 Th remains part of the resistance to weathering mineral constituents [12,21,45].…”

Distributions and Risk Assessment of the Natural Radionuclides in the Soil of Shoubra El Kheima, South Nile Delta, Egypt

Due to heightening concern about radiation hazards protection, activity concentrations of 226Ra, 232Th, 40K in forty soil samples collected from Shoubra El Kheima in the South Nile Delta were measured using gamma-ray spectrometry. The mean activity concentrations of 226Ra and 40K were higher in 20% of the considered samples than the world average values. A comprehensive comparison with up-to-date data was carried out. Spatial distribution maps of the measured radionuclides and radiological parameters were generated. The distributions of natural radionuclides were influenced by the soil organic matter, clay content, and scavenger metals oxides, as well as differences in the physical and chemical attributes and solubility of these radionuclides. The results revealed that industrial activity and agricultural practices in the study area caused an incremental increase in 226Ra and 40K activity concentrations. It can be deduced that although there are intensive industrial activities in this area, the natural radiation that comes from the soil is normal and does not pose a significant radiological hazard to the public. The natural radioactivity of soil in this area needs to be monitored periodically to prevent unnecessary radiation exposure to inhabitants.

“…The different chemical properties (mainly mobility and retention) cause the disequilibrium to exist in the decay chain of uranium-238 [58]. Equilibrium conditions between uranium-238 and radium-226 are rarely verified [44,59], but some examples of quasi-equilibrium are documented [56,60].…”

Population exposure to indoor radon has been proven to increase the risk of lung cancer, and it is considered a leading cause after tobacco smoking. Due to the relatively low outdoor activity concentration, most of the exposure to radon occurs indoors. Radon is generated mostly by the rocks that contain radium-226 either in the soil or in the building materials. Once generated, it enters the buildings directly, due to the activity concentration gradient, or indirectly via a radon carrier. The magnitude and the relative contribution of the entry patterns depend mainly on the building characteristics, the geology, and the living habits of occupants.
