Radiological Investigation on Sediments: A Case Study of Wadi Rod Elsayalla the Southeastern Desert of Egypt

The presence of heavy radioactive minerals in the studied granitoids from which Wadi sediments leads to study exposure emitted gamma rays terrestrial radionuclides, such as 238U, 232Th, and 40K. geological revealed that derived surrounding granitoids, syenogranite, alkali feldspar granite, quartz syenite. mineral analysis confirmed were enriched with minerals, uranothorite well monazite, zircon, yttrocolumbite, allanite. mean activity 40K concentrations are 62.2 ± 20.8, 84.2 23.3, 949.4 172.5 Bq kg−1, respectively, for investigated sediments, exceeding reported limit 33, 45 412 respectively. Public radiation is detected by estimating many radiological hazard indices, radium equivalent content (Raeq), external internal indices (Hex Hin), annual effective dose (AED), gonadal (AGDE), excess lifetime cancer (ELCR). obtained results hazards parameters showed public can induce various dangerous health effects. Thus, application different building materials infrastructures fields not safe. A multivariate statistical (MSA) was applied detect radionuclide correlations estimated granite samples.
