Introduction: This study investigated the exposure rates of background radiations in selected locations
of Najaf and Dhi Qar cities, Iraq.
Materials and Methods: Exposure rates were quantified using a portable Geiger–Müller meter.
Frequent readings of gamma dose rates were recorded (82 and 101 nGy h-1).
Results: The lowest absorbed dose rate was found to be 43.5±17.4 nGyh-1 in Najaf (outdoor
environments), and the highest was 174±8.7 nGy h-1 in Dhi Qar city (outdoor environments). Overall,
the absorbed dose rates of background radiation fell within the worldwide range reported in other
regions.
Conclusion: The selected locations in Najaf and Dhi Qar cities showed normal absorbed dose rates with
no adverse biological effects on people in the studied areas.
