Abstract

Activity concentrations of the Naturally Occurring Radioactive Materials (NORMs) in some bottled drinking water brands obtained from some supermarkets in Accra were analyzed using gamma spectrometry. 40 K activity concentrations were in the range of 3.57 - 5.47 Bq/L, the highest occurring in brand L9. Similarly, 232 Th activity concentrations were in the range of 0.30 - 0.56 Bq/L with the highest occurring in brand L8. 226 Ra was identified in eleven brands with the remaining 5 below detection limit. The highest value (0.53 Bq/L) occurred in brand L9. Comparison of the mean concentrations showed significant differences at (α = 0.05) between the various brands of bottled water. Estimated committed effective doses were generally below 0.1 mSv/a for all age groups with the exception of children <1yr. Estimated lifetime cancer and hereditary risk were done using the ICRP risk assessment methodology.
