Human populations are being exposed to a wide spectrum of radiation from soils as a result
of the availability of radiation sources. Assessing the ecological and health effects of …

Soil pollution caused by radionuclides has become a global concern. However, previous
research has mostly focused on specific sites or limited locations, which may not provide a …

The study found that the activity concentrations of the radionuclides 238U, 232Th and 40K in
the sandstone are 32±13, 29.6±12.2, and 132.6±86.4 Bq kg− 1, respectively. These values …

Different rock types (syenogranite, alkali feldspar granite and quartz syenite intruded by
microgranite dikes and quartz veins) were investigated in the Nikeiba region in Egypt. The …

The existence of radioactivity linked to the heavy-bearing minerals in building materials—
such as granite—has increased attention to the extraction procedure. Granite rocks play an …

The exposed rocks in the Wadi El-Regeita area are quartz monzonite, granodiorite and
monzogranite intruded by andesite and diorite dikes. The monzogranites studied show a …
