This paper investigates the environmental fate of radionuclide decay chains (specially the (238)U and (232)Th series) being released from a conventional mining installation processing ore containing natural occurring radioactive materials (NORMs). Contaminated waste at the site is being disposed off in an industrial landfill on top of a base of earth material to ensure integrity of the deposit ...

naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yalo...

background: natural radionuclides are always present in the environment. human exposure to the background radiation is inevitable. it is therefore important to assess health risk associated with these radionuclides. materials and methods: the distribution of natural radionuclides 238u, 232th and 40k in soil samples collected from all the twenty (20) local governments headquarter areas in ogun s...

Arranged from oldest to youngest, the main granitic rock units exposed in Khour Abalea are metagabbros, cataclastic rocks, ophiolitic melange, pegmatite and lamprophyre dykes. The presence of radioactivity associated with heavy bearing minerals construction materials—like granite—increased interest extraction process. As it turns out, rocks play an important economic part examination area’s sur...

The characteristics of lymphedema on radionuclide lymphoscintigraphy were studied, and the diagnostic value of radionuclide lymphoscintigraphy in lymphedema was evaluated. In this report radionuclide lymphoscintigraphy was performed in 110 cases of clinically suspected lymphedema. A retrospective study method was used to analyze the imaging results. The typical pattern of lymphedema on radionuc...

Introduction: This Study has was  carried out to measure and detect the natural occurred radionuclide content including 226Ra, 232Th and 40K in the  Nile River sediments at various locations in Upper Egypt, from Aswan to El-Minya. Additionally, we determine the absorbed dose rate, the annual effective dose equivalent, and excess lifetime cancer risk also has been calculated. Material and Metho...
