Abstract
The aim of this research is to determine the uranium concentration and its distribution in many sheep organs that live in different region of Iraq. The uranium concentration in tissue samples is measured by using fission tracks registration in CR-39 detector that caused by the bombardment of U235 with thermal neutrons from (241Am-Be) neutron source of thermal flux (5x 103 n.cm-2. s-1). The results show that the maximum uranium concentration in bronchiole tissues of the animals was found in Karbala city (3.706ppm) while the minimum concentration (0.127 ppm) was found in Al-Faluja city, also the same result in lung tissue the maximum value was found in Karbala city (2.313ppm) and the minimum concentration in Al Fluja (0.082). Otherwise, the maximum concentration in liver tissue was found in AdDiwaniyah city (1.156ppm) while the minimum concentration in Al Fluja city (0.153ppm). The uranium concentrations in heart tissues were found various than the previous results. The results of average uranium concentration in each animal were ranged from 0.149 to 1.675 ppm, the maximum values were found in the cities in south region of Iraq.
Highlights
All uranium isotopes are diverse molecular interactions primarily alpha particle (α) emitters.including DNA thatThese alpha particles will travel only may cause in genetic damage [2].about 30 m in soft tissue and, are unable to penetrateDepleted uranium (DU)has the same three isotopes of natural uranium paper, glass, or even the dead but in a different isotopic ratio from superficial layer of skin
DU can enter the body in the form of uranium metal from fragments radiation is derived from the energy, it transfers to matter including biological and as uranium oxides from oxidized DU formed after impact on hard matter, through which it travels
Materials and Methods: Tissue samples were taken from sheep organs that have been living in different Iraqi cities, these cities are specified by numbers as in Table (1): Table (1): The selected locations
Summary
All uranium isotopes are diverse molecular interactions primarily alpha particle (α) emitters.including DNA (genetic material) thatThese alpha particles will travel only may cause in genetic damage [2].about 30 m in soft tissue and, are unable to penetrateDepleted uranium (DU)has the same three isotopes of natural uranium paper, glass, or even the dead but in a different isotopic ratio from superficial layer of skin. These alpha particles will travel only may cause in genetic damage [2]. The danger of depleted uranium particulate and its radioactive daughter products such as circumstances, beta particles are only present a hazard if internalized. DU can enter the body in the form of uranium metal from fragments radiation is derived from the energy, it transfers to matter including biological and as uranium oxides from oxidized DU formed after impact on hard matter, through which it travels. The major uranium oxides energy is dissipated in living tissues by generated are U3O8, UO2 and UO3[3]
