Abstract |
|
|
| The Instrumental Neutron Activation Analysis (INAA) technique was used for qualitative and quantitative analysis of coral reef samples collected from the Safaga harbor at the Egyptian Red Sea coast. Coral reefs were collected to determine the concentration of heavy elements, rare earth elements, and elemental contents. The samples were prepared together with their standards and simultaneously irradiated in Egypt Second Research Reactor (ETRR-2). Gamma-ray spectra from a hyper-pure germanium detector with a relative efficiency of 100% were analyzed. The following elements have been determined Al, Ca, Cl, Mg, Na, V, K, Mn, As, Ti, Ba, Br, Ce, Co, Cr, Eu, Fe, Hf, La, Sc, Sm, Ta, Tb, Th, U, Zn, and Zr. The present work is concerned with the use of instrumental neutron activation analysis to achieve an accurate knowledge about the elemental content in coral reef samples in the Safaga harbor area and identifying potential environmental indicators for heavy metals contamination as well as pollution hot spots around this area for servicing public health for workers, Tourists, and the surrounding population. |
