ABSTRACT:
In this work, the concentrations of natural Uranium
and the annual effective dose (ET in Sv·y-1)
in drinking water for Nineveh Governorate in northern Iraq were determined
using a pulsed-laser Kinetic Phosphorescence Analyzer (KPA). Furthermore, the
relationship between pH for water samples and the concentration of Uranium was
studied. The drinking water samples are taken approximately from all regions of
Nineveh as; 15 samples of tap water are taken from refinery stations, 13
samples of water samples are taken from wells that are used for drinking, and
18 samples of drinking water are withdrawn from wells in Adayyah region (this
region is located near nuclear wastes site). Thus, the total studied samples
are 46. The results of Uranium concentration for all samples ranged from 2.61 ± 0.08
to 9.14 ± 0.012 μg·L-1 with an overall average
value about 5.87 ± 0.046 μg·L-1, and the total annual
effective dose ranged from 2.3 to 8.04 μSv·y-1. The results also
showed that the pH number increases with increasing Uranium concentration and
have, in general, high values in well
water.
