    Abstract: The effect of gamma radiation on the mechanical and chemical properties of x CuO, (70-x) Bi2O3, 20SiO2,10 Na2O, where 0 ≤ x ≤ 30 weight % were carefully studied in order to obtain information about the changes that appear in the structure of the glass matrix with the doping of copper ions. The glass matrix was fabricated by melt-quenching technique... Show More

    Abstract: Ternary Zinc-Sodium-Phosphate glasses doped with copper of the composition 40ZnO-(20-x) Na2O-40P2O5-xCu2O where x =0, 2, 4, 6, 8 mol % were prepared by the tradition quenching method. The effect of Cu ions on density, molar volume and microhardness has been investigated. FTIR was measured in the range (400-1600) cm-1 to investigate the effect of Cu... Show More

    Abstract: The radioactivity concentrations of 226Ra, 232Th and 40K in thirty samples representing the technically Naturally Occurring Radioactive Materials (NORM) in the Egyptian natural gas were investigated. The investigations were performed using a gamma ray spectroscopy technique. The obtained data were used to establish a data base for NORM concentratio... Show More

    Abstract: This paper presents the environmental effects of gas flaring on pH values of the soil and rain water in some areas in Niger Delta. Different soil samples and rain water at various proximities from the gas flaring locations were taken. The samples collected were evaluated to determine the pH values of rain-water and that of the soil in the area unde... Show More
