Abstract
The gross alpha and beta data were generated from EURISYS MEASURE IN20 low Background multiple
(eight) channels alpha and beta detector stationed at Center for Energy Research and Training (CERT), Ahmadu Bello
University, Zaria. Eight samples of drinking water collected from local boreholes in Gombe metropolis were evaporated
to obtain the residue. The residue was later counted for gross alpha and beta activity. The mean gross alpha and beta
activity obtained were 1.03 and 18.69 Bq/l respectively. The gross alpha and beta activity values were used to estimate
the annual committed effective dose (ACED) due to alpha and beta emitting radionuclides. The mean ACED obtained
due alpha emitting radionuclides were 0.41, 0.82 and 1.65 mSv/yr for infants (≤ year), children (1-12 years) and
teenagers/adults (> 12 years) respectively while the ACED obtained due to beta emitting radionuclides were 7.51, 15.01
and 30.02 mSv/yr for infants, children and adults respectively. The results obtained were compared with the world
standards and realized that most of the sample locations were above the world standards. It was concluded that the water
collected from these sample locations will be threat to human health and the environment. Therefore, it was
recommended that further studies need to be carried out to ensure the safety of the masses around the areas and the
environment
