Abstract
This thesis deals with study of the suitability of site for the construction the nuclear power plant. This facilitates comparative study between the results obtained from this work and those, which might occur after the construction of the plant. To assess this purpose and to study the impact of power plant on the surrounding area, the study of environmental radioactivity in different environmental compartments and study hydrochemistry and isotope hydrology of water resources in area under investigation took place. The thesis is subdivided into two parts; the first one deals with study of the radioactivity in the environment and the other part is studied hydrochemistry and isotope hydrology of water resources. Each part is subdivided into three main chapters including the introduction, the experimental, and the results and discussions.
For the first part, it is intended to in chapter-I, the introduction, deals with presence of radionuclides in different environmental compartments and the potential pathways to the man. In this chapter, also, discuss the steps for selection El Dabaa site and the factor which controlled for site selection. Also deals with the literature review of similar work on environmental radioactivity.
Chapter two contains the experimental part. In this chapter, the methods of samples collection were described for collected water samples, biological samples, soil and sediment samples. In this chapter, the description of used instrument for nuclear spectroscopic techniques was depicted. This instrument includes a hyper pure germanium detector. The instrument is calibrated and used for radioactivity measurements. The adjustment of this instrument was elaborated through energy calibration, efficiency determination and background subtraction.
Chapter three includes, the results and discussions. This chapter deals with environmental surveillance for a nuclear measuring program for determination of naturally occurring radioactive elements in different environmental samples to assess highly qualified non destructive and quantitative determinations. In this chapter, the radioactivity levels of main naturally occurring radionuclides of potassium-40, uranium-238(radium-226), and thorium-232 were determined in environmental samples together with caesium-137 if present. The analysis of samples includes several soil, sediment, water and biological samples. In case of soil and sediments giving the following r
