Preliminary studies on groundwater samples from selected wells in University of Cape Coast and
its surroundings in the Central region of Ghana have been carried out to determine the annual effective dose
from intake of naturally occurring radionuclides. Measurements were carried out using gamma spectrometry.
The average annual effective doses obtained in this study were 0.15±0.04 mSv for Apewosika, 0.17±0.03 mSv
for Amamoma, 0.14±0.01 mSv for Kokoado and 0.17±0.03 mSv for Kwaprow respectively. The values
calculated were about 1.7 times higher than WHO guidance levels of 0.1 mSv/y from intake of radionuclides
in water. 232Th and 40K levels are lower than the world average values whilst 238U levels are slightly higher. The
total annual effective dose in the study area is lower than the ICRP recommended public dose limit of 1 mSv
per year.
Key words: Activity concentration, annual effective dose, p-values, radionuclides, underground water, University of Cape Coast,
