In this study, the concentrations of radioactive including (_^40)K (_^226)Ra, and (_^232)Th in some tissues of most common Carpio fish collected from Baghdad city and their in Tiger river which is an important water source for irrigation and drinking in in Iraq during 2015-2016 were investigation and studied using a high purity germanium detector .
The results of fish sample obtained showed that the the effective activity concentration of (_^40)K : 97.65 Bq/kg in S_5 sample to 567.34 Bq/kg in S_9 , (_^226)Ra : 1.17 in S_3sample to 33.51Bq/kg in S_9 sample, and (_^232)Th are 2.39Bq/kg in S_9 to 11.89 Bq/kg in S_5 sample . These confirm that that never affected on the integrity of the environment and fisheries at Baghdad province, its indication a certain degree of bio-accumulation. That’s refers to conditions will help the fish to withstand sudden changes if available oxygen generators .
