Radon Activity Concentration Measurements in the Water Collected from the Lower Zab River in the Kurdistan Region of Iraq

This study aims to assess radon levels in the water of Lower Zab River. Knowing concentrations is crucial for understanding potential risks human health and implementing protective measures. ARAD7-H2O detector has been used measure concentration 28 samples from River Kurdistan Region Iraq. Results show that activity ranged 0.5 4 Bq.L−1, with an average 0.61 resulting annual effective dose (AED) varied 0.137 60.06 Sv.y−1, 12.08 Sv.y−1. The AED measured are below reference recommended by ICRP World Health Organization. Consequently, LZR suitable consumption use does not present any hazards related exposure.
