Radon (222)‎ content in bottled water of Kurdistan region using active and passive methods

الملخص EN

In this research, radon activity concentrations in the available types of bottled drinking water samples were available in Iraqi Kurdistan region markets were measured by using passive (CR-39 SSNTDs) and active (Durridge RAD-7-H2O with a closed loop) methods.

Radon concentration in bottled water ranged from (0.050 to 0.585) Bq/l for CR-39 with a mean value (0.143) Bq/l and ranged from (0.030 to 0.213) Bq/l for RAD7 with a mean value (0.074) Bq/l.

The values of activity concentration were below the Maximum contamination level (MCL) suggested by USA-EPA which is (11.1) Bq/l.

The rate of total annual effective dose for human drinking this water is also determined.

The results indicate that the total annual effective doses were lower than the MCL of 0.1mSv/y proposed by (WHO, 2004) for intake of radionuclide in drinking water.

The Cancer risk and lifetime heredity levels were also calculated and the mean value was very low compared to the acceptable limit of 1.0x10-3.
