Updated description of Radioactivity levels in the marine environment along the Exclusive Economic Zone (EEZ) of Qatar from
A study on 137Cs, 40K, 226Ra, 228Ra, and 238U was carried out along the EEZ of Qatar. Results serve as the first ever baseline data. The level of 137Cs (mean value 1.6 ± 0.4 Bq m-3) in water filters was found to be in the same order of magnitude as reported by others in worldwide marine radioactivity studies. Results are also in agreement with values reported from other Gulf regions. The computed values of sediment–water distribution coefficients Kd, are lower than the values given by IAEA. Measurements were carried out for bottom sediments, biota samples like fish, oyster, sponge, seashell, mangrove, crab, shrimp, starfish, dugong and algae. The ‘concentration factors’ reported for biota samples are below the levels published by IAEA and cause no significant impact on human health for seafood consumers in Qatar.
