Uranium Concentration and its Associated Health Hazards in Drinking Water of Nineveh Province (Iraq)
Measurements of uranium concentration in water samples for a total of 11 selected locations from Nineveh province were chosen for analysis of uranium concentration using fission track registration technique. A known volume of the water(two drops) was dropped on the CR-39 track detector. All the samples were irradiated with thermal neutrons in Am-Be neutron source with a thermal neutron fluence of about(3.0249x10 n.cm ). Uranium content in water samples of the study area ranges from 7.9 to 19.12µg/l, the 9 2 activities of U, U and U in taps water of Nineveh are in the range of9.75, 0.46 and 9.84mBq/l to 23.6, 1.1 238 235 234 and 23.8mBq/l respectively and the range of U is from20.06 to 48.5mBq/l. The results of the annual effective nat dose (E ) (µSv/y) of the uranium isotopes ( U, U, U ),ranged from 3.5, 1.7, 3.6, 7.3 in Talskuf to 8.6, 4.0, 8.6, T 238 235 234
Evaluation of radiological risk of uranium in well water in Nineveh Governorate, northern Iraq
Int. J. Nuclear Energy Science and Technology, 2023
Gamma spectroscopic technique with NaI(Tl) was used to measure uranium activity in well-water samples collected from the Nineveh Governorate in northern Iraq. The obtained results determined chemical toxic and radiological risks to humans through uranium content, either carcinogenic or non-carcinogenic, during lifetime utilisation by the population in the region. The activity of uranium ranged from 1.09 to 4.86 Bq.L-1. The radiological risks for excess cancer mortality fluctuate between 4.09 × 10-5 and 1.82 × 10-4 , while those for cancer morbidity risk range from 6.26 × 10-5 to 2.79 × 10-4. The measured lifetime average daily dose ranged from 1.20 μg.kg-1 day-1 to 5.37 μg.kg-1 day-1. All samples are clearly below the recommended value (4.53 μg.kg-1 day-1) except sample (W12). The current research may be of imperative significance in radioactive epidemiological evaluation, diagnosis and forecast of uranium infections within the current region.

This study aimed to assess Uranium content measurement in drinking water for some regions in Sudan using Laser Flourometry Technique.Water samples were collected from different region in Sudan in Sudan for the time interval from Feb. to Dec. 2008.The sources of these samples comprise dug wells, tube wells and hand pumps. Uranium is determined using laser fluorometry technique, while as for trace elements in soil and plant samples Inductive Coupled Plasma (ICP) was used.The values of Uranium activity in the water samples varies from 1.7484 Bq/L to 0.1364 Bq/L. These values are compared with safe limit values recommended for drinking water, and compared with quantity of radiation background for each area, in order to see if some correlation exists between the concentration of uranium and radiation background. The calculated values of Uranium activity in the water samples from different areas of state in Sudan ranged from 1.7484 Bq/L to 0.

Exposure due to natural radiation is of particular importance because it accounts for the largest contribution (nearly 85 %) to the total collective dose of the world population. Uranium is a heavy metal that is not only radiologically harmful but also a well-known nephrotoxic element. In the present study, about 30 water samples were collected from open-wells ,Bore well and supplied water from taps, from the coastal region of Porakad, Allapuzha District. The Uranium concentration in the water samples was analyzed by light-emitting diode (LED)-based Ultraviolet (UV) fluorimeter (Quantalase Enterprises Pvt. Ltd, Indore, Madhya Pradesh, India). The associated age dependent Uranium intake was estimated by taking the prescribed water intake values. Most of the water samples had the Uranium concentration below the standards set by United States Environmental Protection Agency (30 ppb).
Laser-Induced Fluorimetry has been used to measure the concentration of uranium in the ground water samples collected from the selected study locations of Bangalore city, India. The concentration of uranium in the collected water samples is found to be in the range 0.24 μg/l to 770.1 μg/l, with a geometric mean (GM) value of 18.9 μg/l. About 35% of the water samples show the concentration of uranium above the safe limit of 30 μg/l, set by the United States Environmental Protection Agency (USEPA). The annual effective dose associated with the ingestion of uranium by the adult population of the region has been estimated using the International Commission on Radiation Protection (ICRP) and World Health Organization (WHO) guidelines. Few physicochemical parameters of water such as pH, Total dissolved solids (TDS), major cations, major anions, and trace elements were also measured. The correlation coeffi cient among the measured parameters was determined to fi nd the dependence, if any, on the concentration of uranium in the water samples.

In this work, Uranium concentrations in groundwater and soil samples from some areas of Al-Najaf city, Iraq were measured solid state nuclear track detector (CR-39) detector technique. The uranium concentration in groundwater samples was found to vary from (1.617782869±0.04342) μgl −1 to (5.079235843±0.137827) μgl −1 , while in soil samples vary from (0.093558±0.000938) ppm to (0.184325±0.017511) ppm.

Purpose: As a way of prevention, we have measured the activities of uranium and radium isotopes (234 U, 238 U, 226 Ra, 228 Ra) for 30 drinking water samples collected from 11 wells, 9 springs (6 hot and 3 cold), 3 commercialised mineral water, and 7 tap water samples. Methods: Activities of the Ra isotopes were measured by ultra-gamma spectrometry using a low background and high efficiency well type germanium detector. The U isotopes were counted in an alpha spectrometer. Results: The measured Uranium and radium activities are similar to those published for other non-polluting regions of the world. Except in one commercialised gaseous water sample, and in two hot spring water samples, the calculated effective doses during one year are inferior to the reference level of 0.1 mSv/year recommended by the International Commission on Radiological Protection. Conclusion: These activities don't present any risk for public health in Morocco. The sparkling water of Oulmes is occasionally consumed as table water and waters of warm springs are not used as main sources of drinking water.

The mass concentration of uranium in water samples collected from the Bathinda district of Punjab state, India, was estimated using the laser fluorimetric technique. The study region has shown a pronounced number of cancer cases in the recent period. The study aims to calculate the human radiological risk and chemical toxicity associated with uranium consumption through drinking water. The mass concentration of uranium was found to vary from 0.48 to 571.7 µg/l with a mean value of 84.70 µg/l. The radiological risk due to consumption of uranium through contaminated drinking water was observed to be in the range of 1.34 × 10-6 to 1.60 × 10-3 with a mean value of 2.37 × 10-4.
