الملخص EN

This research is measuring the radioactive gas radon in samples of water (water liquefaction and river) in district of Al-Qassim for Babel province (100 Km) south of Baghdad,18 samples were collected from different regions from Al-Qasim, using the electronic radon detector RAD7, and the average concentration of radon ( 0.

17± 0.08 Bq.L-1) , and effective dose for human exposure to radon was (0.009) mSv.y-1.

And it was found that the concentrations of radon in the water are within normal limits set by the relevant organizations as the maximum allowable concentration of radon in water (11.1 Bq.L-1) (As defined by the Environmental Protection Agency).

This subject has been chosen because of the importance of water in human life and living, and the lack of previous studies in the study area
