Analysis of radon concentration in drinking water in some locations at Baghdad City Iraq

الملخص EN

One of the most important characterizations of social health is existence the availability of safe drinking water.

Since one of the sources of water contamination is nuclear contamination from radon gas, so in this research 222Rn concentration levels in water supplies in Baghdad (capital of Iraq) is investigated.

10 water samples were collected and analysed using RAD7 detector.

Review the results of these measurements show that, Radon activity concentration in the range of (0.289- 0.072) Bq.L-1 with an average value of (0.1) Bq.L-1 ,and the effective dose for human exposure to radon was (0.008) mSv.y-1 .

Upon comparing the radon concentration values obtained with EPA it was found they were far below the maximum contaminant level of EPA (11.1 Bq.L-1) , To reduce radon concentration, it is better to effective dose due to radon ingestion is consistent with WHO (1 mSv.y-1 ) recommended dose level with keep water in open pools in contact with air before the water is delivered to users.

Has been chosen this subject of the current study of the importance of water in human life and living, and the lack of previous studies in the study area.
