Background: Natural Radioactivity, though
natural requires concentration monitoring, especially
for the health/ environmental checks of the
populace. Materials and Methods: The activity
concentrations of 40K, 238U and 232Th in the waters
from wells with depths ranging between 141.0 -
214.0 feet were randomly sampled and determined
from 20 locations in Ago-Iwoye town in South
Western, Nigeria. Results: The activity concentrations
obtained were in the ranges of (9.9-50.9)Bq/kg with
mean value of (25.1± 10.7) Bq/kg for 40K, (BDL-15.0)
Bq/kg with mean value of (1.2 ± 3.2) Bq/kg for 238U
and (BDL-6.2) Bq/kg with mean value of (1.6 ± 1.7)
Bq/kg for 232Th. Conclusion: According to the results
obtained for the activity concentrations from 20 well
water samples in Ago Iwoye, Southwestern, Nigeria it
was observed that the v40K, 238U and 232Th values
were still within the tolerance level indicating minimal
radiological health burden on the human populace
and the environment. Iran. J. Radiat. Res., 2010 7 (4):
