This paper presents the concentrations of naturally occurring radionuclides 226 Ra, 232 Th and 40 K measured in groundwater samples collected from Aden governorate South of Yemen Region using gamma spectroscopy. A total of 37 groundwater samples were collected from four areas in Aden governorate. The average activity concentrations for groundwater from Beer Ahmed area were 1.60 Bq/L, 1.25 Bq/L and 16.90 Bq/L for 226 Ra, 232 Th and 40 K respectively and from Beer Fadle area were 1.45 Bq/L, 0.87 Bq/L and 19.8 Bq/L for 226 Ra, 232 Th and 40 K, respectively, while that for groundwater samples from Daar-saad area were 1.27 Bq/L, 1.18 Bq/L and 18.28 Bq/L for 226 Ra, 232 Th and 40 K, respectively and Al-Masabian area were 1.55 Bq/L, 1.421 Bq/L and 19.03 Bq/L for 226 Ra, 232 Th and 40 K respectively. Furthermore, annual effective dose equivalent of ingestion of these waters was calculated. The results showed that the annual dose obtained in the present study was much higher than the recommended value (0.1 mSv/year) as reported by WHO. The results were compared with those for drinking water.
