A Study of the Concentration of Chromium and Radioactivity of Radioisotopes in the Ingessana Hills Region

Abstract

This study focused on the exploration of chromium metal and its use in the industriesthat are selected for its utmost importance. In this study, glowing X-ray techniques were used to determine the concentration of chromium in the in the Ingessana Hills in the Blue Nile region.And also was the use of a gamma-ray spectroscopy to determine radioactivity of radionuclides found in the Ingessanahills. A total of 30 rock samples were taken from this area, which were analyzed by XRF. Each sample was (25g) in the form of powder and was placed in the machine and according to the concentration of each element in the sample. The analysis showed that the average concentration of chromium (671550 ppm)), And this value gives about (67%) a very high percentage of chromium components, after the operation of the statistical results and take theaveragevalues. The concentration of chromium obtained in the Ingessana Hills is a significant proportion of the world markets. The cost of a kilogram of ferrochrome is about US $ 3.00, while the price of chromium is 1Kg high purity (99.5%) between US $ 30.00 to US $ 50.00[73,74], where the price of chromium has been shown in international markets. It’s believes that these concentrations can contribute to the economy if exploited and invested correctly. This is due to the X-ray sensitivity of the fact that heavy elements such as chromium emit high-energy x-ray photons more than photons of visible light, because the photon energy is proportional to the square of the atomic number of the element. The Gamma ray spectroscopy is one of the best techniques to study radioactivity of radionuclides, They are short-wavelength and high-frequency rays.
