Abstract
This study examines the levels of radon gas (²²²Rn) and the associated annual effective dose (AED) in
potable water supplies utilized for domestic purposes in the Al-Khidhir District, Al-Muthanna
Governorate, southern Iraq. In the study area, which included both the eastern and western regions of
Al-Khidhir City, 230 water samples were gathered from 23 residential areas. A calibrated RAD7 radon
in air detector from the Durridge Company in USA was used to take the measurements. Water aeration
and humidity control were done according to standard protocols. The average radon concentration in the
water samples was 10.30 Bq/L, with a range of 0.29 to 33.01 Bq/L. the average annual effective doses
from inaling radon were 0.0074 mSv/y, with a range of 0.000328 t0 0.07587 mSv/y. According to the
European Union (0.1 mSv/y) and the World Health Organization (100 Bq/L), all recorded values were
significantly below the uppermost permitted limits. The local geology, soil texture, building age, and
water distribution network integrity all contributed to the variations in radon levels in various locations.
Long-term use of radon-contaminated water at homes, may raise the risk of radiation exposure even
though the levels detected were low. This study provides vital baseline information for environmental
radiation monitoring and public health protection in southern Iraq.
