Radioactive Doses Contamination in Al Tuwaitha Nuclear Site, Using GIS Techniques

Abstract

In this paper, the authors aim to introduce contamination in Al Tuwaitha nuclear site, Iraq using GIS techniques and visual interpretation. This contamination problem draws attention to the new result of high-radiation dose equivalents found in part of the country. The radiation levels in Al Tuwaitha nuclear site, compared with the international standards of UNSCEAR 2000 and world nuclear association (WNA 2011), the absorbed doses in the study area vary between (0.01-140) mrad/hr, in Al Tuwaitha nuclear research center. The maximum radiation dose was nearby the Russian 5 MW reactor. The absorbed dose in Russian 5 MW reactor was about (140) mrad/hr which is the highest hotspot in Al Tuwaitha nuclear research center. The obtained values of the average absorbed dose rate level are exceeding the permitted level by (9500) times higher than environmental levels given by UNSCEAR (2000).
