Abstract
In the light of the peaceful nuclear power plants (NPPs) project of the United Arab Emirates (UAE), the operation license has been issued and the first unit is being in commercial operation. This work deals mainly with radiological surveillance of the coastal boarder and some Islands of UAE as a baseline reference natural and artificial radioactivity mapping. Ultra-sensitive hyper pure Germanium (HpGe) detector was used to carry out the non-destructive gamma measurements. The area of study was divided into; Abu Dhabi region, northern emirates and islands. About 85 soils, shore sediment and water samples were collected based on the scientific sampling mechanism. The samples were analyzed for X-ray diffraction mineralogy (XRD). The radioactivity in Bq/kg of the natural 238U(226Ra), 232Th and 40K were calculated for all the collected samples. The artificial 137Cs was also observed in very low activity. The hazard indices were also calculated and found to be less than the recommended international and regional limits. The correlations between the measured radioisotopes were also depicted. The results were compared, presented and given in 3D histograms.
Highlights
The United Arab Emirates is the first state in the Middle East to operate nuclear power plants for electricity production
The preoperational monitoring is a must for any nuclear power plants safe operation
The Surveillance and monitoring along the United Arab Emirates (UAE) coastal areas and some islands have been carried out to ensure that the radiation levels and doses received to the public are below the authorized national and international limits
Summary
The United Arab Emirates is the first state in the Middle East to operate nuclear power plants for electricity production. Preoperational monitoring mapping is a vital target to be carried out as pre-operational and postoperational safety measures. This natural background forms a baseline which the levels and impacts of other sources of radioactivity in the environment are subjected to evaluation. The UAEs started to commercially operate the first nuclear power plant (NPPs); the operation license for the first reactor has been awarded in Fab. 2020., There are very limited studies on the evaluation and pre-operational monitoring of natural and man-made radioactivity levels in the country (UAE). Establishing a baseline reference radiological map before the full commercial operation of the UAEs nuclear power plants is the main target and objective of this paper including the hazard indices calculations to evaluate any potential environmental threat
