|
| Measurements of uranium concentration in water samples for a total of 10 selected locations from Aden governorate, Yemen, were chosen for analysis of uranium concentration using high purity germanium detector (HPGe). The measured uranium concentrations were used to determine uranium isotopes with their ingested radiological toxicity risk (annual effective dose of uranium isotopes) from consumption of the water samples in the present study. The results show that the Uranium content in drinking water samples ranges from (0.178±0.0171) to (2.66±0.256)μg/l, with an overall average value (1.36±0.131)μg/l, the activities of 238U, 235U and 234U in drinking water samples ranges from (0.219, 0.0102 and 0.226)Bq/l to (3.28, 0.153 and 3.37)Bq/l) respectively with an overall average value (1.68±0.162), (0.078±0.0075) and (1.72±0.165)Bq/l and the range of Unat is from (0.456 to 6.81)Bq/l with an overall average value (3.48±0.335)Bq/l. The results of the annual effective dose (ET)(μSv/y) of the uranium isotopes (238U, 235U, 234U) ranged from (7.23, 0.352 and 8.08)μSv/y to (107.88, 5.25 and 120.70)μSv/y respectively with an overall average value (55.11±5.30, 2.68±0.258 and (61.66±5.94)μSv/y. The annual effective dose of natural uranium in all water samples to the adult members of the population within the limit (0.016 to 0.234)mSv/y with an average value (0.119±0.011)mSv/y. We concluded that the average value of the uranium concentrations and total average of the annual effective dose in drinking waters samples under study were lower than the recommended value of ICRP (1.9 mg/l and 1mSv/y) respectively. Therefore, the drinking water at the study area in Aden governorate can be considered as safe as long as Uranium concentration is concerned and does not constitute a danger or hazard to the citizens.
