Chapter 4: Results and Discussion

Our present work is focused on measuring the activity concentration of above natural radionuclides in sediment samples in different cities along Red sea coastline, Egypt. The main aim of the radiation protection view point is to study the activity concentrations of naturally occurring radionuclides and the extent of their exposure to population. Radionuclides present in the environmental media are generally found in low concentration. Detection and intensity measurements of weak gamma activities are more and more playing a vital role in physics experiments and industrial investigation. The most important naturally occurring radionuclides present in sediment are not uniformly distributed; the knowledge of their distribution in sea sediments plays an important role in radiation protection and measurement.
