Abstract

This research work aims to measure the concentration of tritium activity in the Tigris river and samples of tap water collected from different places of Al-Amara city in Misan province using a Tri-Carb 3110TR liquid scintillation counter (LSC) and to calculate an annual effective dose due to the ingestion of water samples. The mean values of the tritium activity concentrations measured in the water samples were 0.562 ± 0.126 Bq/L (4.763 ± 1.075TU) and 0.521 ± 0.060 Bq/L (4.422 ± 0.512TU) for Tigris River and tap water samples, respectively. The mean annual effective doses are given to the infants, children and adults because of the intake of the tritium were (252.95 ± 57.116) ×10–5 μSv/y and (234.81 ± 27.222) ×10–5 μSv/y, (354.13 ± 79.962) ×10–5 μSv/y and (328.734 ± 38.111) ×10–5 μSv/y, and (738.614 ± 166.778) ×10–5 μSv/y and (685.645 ± 79.489) ×10–5 μSv/y for Tigris river and tap water samples, respectively. The results indicated that the concentrations of tritium activity in measured water samples have been found below the limit of 100 Bq/L, which is the recommended measure by the European Commission for drinking water, and the recommended annual effective dose by the World Health Organization for the members of the public was much less than the individual dose criterion of 100 μSv/y. Hence, the waters of the Tigris river and tap in the study area (Al-Amara city) are not threatened to cause health risks because of tritium concentration.

用液体闪烁计数器测量伊拉克米桑省阿马拉市水样中的氚活性浓度

本研究工作旨在使用Tri-Carb 3110TR液体闪烁计数器（LSC）测量底格里斯河和从米桑省Al Amara市不同地方采集的自来水样本中的氚活性浓度，并计算因摄入水样而产生的年度有效剂量。底格里斯河和自来水样品中测得的氚活性浓度的平均值分别为0.562±0.126 Bq/L（4.763±1.075TU）和0.521±0.060 Bq/L4.422±0.512TU。婴儿、儿童和成人因摄入氚而获得的年平均有效剂量分别为（252.95±57.116）×10–5μSv/y和（234.81±27.222）×10-5μSv/y、（354.13±79.962）×10-5μSv/y和（328.734±38.111）×10 5μSv/y，底格里斯河和自来水样本分别为（738.614±166.778）×10-10-5μSv/y和（685.645±79.489）×，分别地结果表明，测得的水样中的氚活性浓度低于100 Bq/L的限值，这是欧盟委员会对饮用水的建议措施，而世界卫生组织对公众的建议年度有效剂量远低于100μSv/y的个人剂量标准。因此，研究区域（Al Amara市）的底格里斯河和自来水不会因氚浓度而造成健康风险。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
