Abstract

Radon monitoring has been on increase worldwide because it poses significant health hazard to
human being. In this study, radon concentration in wáter was measured to assess the corresponding
radiological health implication in the study area. Sixty (60) samples of wáter were analyzed using
RAD7, electronic radon detector with special accessory. The measured radon concentration in
water samples rangess from 1.8 ± 0.2Bq????−1 to 17.2 ± 1.3Bq????−1 with mean value of 7.2 ± 1.8 Bq????−1.
The annual effective dose exposure to individual due to the measured radon concentration was
found to be 0.020 mSv ????−1, which is lower than the recommended safe limit of 0.1 mSv????−1 set
by WHO and EU council. The level of radon activity concentration in the study area is still within
the normal range, thus should not pose any significant health risk to the population.
