Description
Water from bedrock frequently contains higher concentrations of natural radionuclides than water from other sources. Groundwater from Assalamia-Alhomira and Juban areas (southeast of Sana'a) and hot spring water from Dempt area (south Sana'a) in Yemen were analyzed for 226Ra, 232Th and 40K activity concentrations. The average activity concentrations for groundwater from Assalamia-Alhomira area were 4.04 Bql-1 and 1.81 Bql-1 for 226Ra and 232Th, respectively, while 40K was not detectable, while that for groundwater samples from Juban area were 2.95 Bql-1, 0.72 Bql-1 and 34.9 Bql-1 for 226Ra, 232Th and 40K, respectively. On the other hand, the activity concentrations for hot spring water from Dempt area were 3.48 Bql-1, 1.01 Bql-1 and 16.05 Bql-1 for 226Ra, 232Th and 40K, respectively. Also annual effective dose equivalent of ingestion of these waters was calculated. The results showed that the annual dose equivalent obtained in the present study was much higher than the recommended value (0.1mSvyear-1) as reported by WHO. The results were compared with those for drinking water. © 2011 Elsevier B.V.
