  ABSTRACT

  Background : The application of DU emanation for first time contaminated certain areas in the south west region of Iraq after the second Gulf war (1991). These contaminated areas were discovered in 1994. Radioactive contamination was detected using the nuclear enterprise PCM5/1 in soil samples collected from two regions near by grazing lands. This study was done for assessment of DU contaminated soil in the regions under study.

  Materials and Methods : Portable detector was used for radiation measurement of the contaminated area. Samples from each region were selected and taken to Baghdad kept in plastic bags for gamma ray spectroscopy measurement. Gamma-ray spectroscopy system consists of high purity germanium (HPGE) detector surrounded by appropriate shield. The measurement of detector efficiency using (GDR) computer programs, supplied by Canberra Company was used to analyze gamma-ray spectrum. The activity of 234 Th, 235 U, 238Pa and other natural isotopes were measured.

  Results: The measurement by gamma –ray spectrometry system showed that six samples were heavily contaminated with DU, because the presence of 243Pa and 235U peak and the percentage ratio between 235 U/238U were less than 0.005, when both international mathematical methods, namely IAEA and Kosovo, were used. Because of existence of radiation equilibrium between 234Th and 234Pa, the measurements should be accurate.

  Conclusion: The result showed that six of the samples were heavily contaminated with DU and there is a good agreement between the two methods. Because of the accuracy and ease of the Kosovo method, it is recommended for future investigations.

Keywords: Kosovo Method, south west of Iraq, soil contamination, Depleted uranium
