One of the most characterizations of social health is the existence availability of sources irrigation water. Since the main source of water, contamination is radon gas. Six regions in Karbala province in Iraq were chosen to evaluate Radon level in underground water-samples by using (SSNTD-CR-39) Detector. The current measurements showed that highest level was in Al-Horr region to be 4.152±2.2Bq/L, where lowest concentration was in Hay-Rumdan 2.165±1.6Bq/L. The maximum Annual-Effective Dose (AED) was found in Al-Horr to be 14.34±3.5μSv/y, whereas the minimal value indicated at Hay-Rumdan 8.66±3.1μSv/y. In general, it has been found that Radon-level concentration, in the studied groundwater-samples, was less than allowed permissible value 11.1Bq/L and annual effective-doses were below the recommended international value 1mSv/y. Therefore, groundwater in all underground water studied in Karbala province is safe where the focus of radon obsession is not a public concern.
