Abstract The solid-state nuclear track detector tech-
niques were used in this study to measure the level of

uranium isotopes (238U, 235U, and 234U) that were found
in water samples collected from marshes (Ahwar) at
Dhi-Qar governorate, southern Iraq. The apparatus used
for this study purposes was TASTRAK CR-39 plastic.
In this study, we measured the following risk factors: the
radiological risk, annual effective dose (ET) of uranium
isotopes, the excess cancer risks, the chemical toxicity
risk, lifetime average daily dose (LADD), and hazard
quotient (HQ). Using different techniques, the water

samples were analyzed for other physicochemical prop-
erties such as hydrogen ion concentration (PH), electri-
cal conductivity (EC), and total dissolved solids (TDS).

This study has proved that uranium isotopes were found
in different concentrations in all water samples that were

taken from different places of marshes. The concentra-
tions of uranium isotopes in the collected samples were

ranging from 0.87±0.072 to 1.89±0.093 μg/L, with an
average value of 1.23±0.05 μg/L. The average values
(with SE in Bq/L units) for 238U, 235U, and 234U were
1.51±0.06, 0.07±0.002, and 1.53±0.06, respectively,
while the average values of ET, LADD, and HQ were
0.107±0.004 mSv/year, (0.326±0.013) × 10−3
, 0.040

±0.001 μg/kg.day, and 0.066±0.002, respectively. In
addition to the previous results, the study has showed
that the average value of PH, EC, and TDS with the SE
were 7.84±0.22, 3999.95±294.45 μS/cm, and 2601.35
±197.77 mg/L, respectively. The results revealed that
the concentrations of uranium isotopes in the studied
samples were below the instrumental detection limit (1.9
μg/L). Comparing the results of radiological risk and
chemical toxicity risk of this study with those published
by global organization and universal researches, it was
found that these concentrations were within the allowed
limits permissible to human consumption and domestic
use. Besides these results, the values of EC and TDS
were higher than the permissible limits of Iraqi and
international standards for irrigation purposes. For all
the aforementioned, it might be concluded that there are
no health risks to humans by drinking the water of the
marshes of Dhi-Qar Governorate according to uranium
levels, but cannot be assumed to be of good quality.
