The present work used the gamma-ray spectrometric data to evaluate the radioactive environmental assessment in Wadi Diit and Wadi Sermatai area. The sediments in the studies area consider important materials inreched with economic minerals such as ilmenite, magnetite, zircon, sphene, apatite, garnet, and rutile are applied in many important industrial applications. Thus, the high emitted radiation from the sediments will serve an adverse health effect. Therefore, the assessment of the radiological hazard indices are very important. In Diit area, the mean concentrations of U-238, Th-232, and K-40 are 29.25 +/- 14.79, 17.92 +/- 10.61 and 347.63 Bq kg(- 1), respectively, which is lower than the worldwide average value. At the same time, in Sermati area, the mean of activity concentration U-238 (37.46 +/- 12.79 Bq kg(- 1)) and K-40 (798.15 +/- 277.12 Bq kg(- 1)) is exceeded the worldwide value, and Th-232 was not exceeded (22.88 +/- 8.86 Bq kg(- 1)). The obtained radiological hazards parameters depicted that public exposure to emitted gamma radiation cannot induce various dangerous health effects.
