Natural radionuclides and dose estimation in natural water resources from Elba protective area, Egypt

Abstract

The concentrations of the natural radionuclides (226)Ra, (232)Th and (40)K in 15 different water samples from Elba protective area, south-eastern desert of Egypt, have been determined using NaI(Tl) detector. Gamma ray spectrometric analysis was performed and the concentrations obtained for each of the radionuclides expressed in Bq l(-1) ranging from 1.6 to 11.1 for (226)Ra, 0.21 to 0.97 for (232)Th and 9.1 to 23 for (40)K. A reasonable correlation was found between (226)Ra, (232)Th concentrations and pH, although no general trend was observed with conductivity and total dissolved solids. The mean effective doses of 0.56 mSv y(-1) for (226)Ra, 0.065 mSv y(-1) for (232)Th and 0.04 mSv y(-1) for (40)K were estimated for the ingestion of these waters by adults.

Assessment of radiation hazards a result of natural radioactivity in water from Abyan delta, Yemen

“…Also Th activity concentrations obtained in this study match with that reported by Saqan [25] for hot spring water at Afra, Barbeita and Al-Amir sites in Jordan and is higher than that reported by [20,21,23,24], and lower than that reported by Agbalagba [26] for lake water in Nigeria. On the other hand, 40 K values in the present study match with those values reported by El-Mageed et al [3] for spring water Yemen (Dempt) and El Arabi [24] for groundwater in Egypt (Elba) and lower than values reported by Agbalagba [26] in Nigeria.…”

“…As can be seen from Table 3, 226 Ra values from the present work are higher than that reported by Ahmed [20] for ground water in Egypt (Qena and Safaga), Al Fatih [21] for ground water in Sudan, Zhuo [22] for ground water in China, Kpegl [23] for surface water in Ghana. Also it's found that they are lower than the values reported by [24], [25], [26] and [4]. Also Th activity concentrations obtained in this study match with that reported by Saqan [25] for hot spring water at Afra, Barbeita and Al-Amir sites in Jordan and is higher than that reported by [20,21,23,24], and lower than that reported by Agbalagba [26] for lake water in Nigeria.…”

Natural Radioactivity in Soil and Water from Likuyu Village in the Neighborhood of Mkuju Uranium Deposit

“…This value was only 1.5 times higher than the value reported by El Arabi et al (2006) in natural water resources from Elba protective area in Egypt [13]. …”

Natural Radioactivity in Groundwater in Phra Nakhon Si Ayutthaya Province

“…Similarly, Zhuo et al (2001) [7] reported the maximum value of 0.93 Bq L -1 was found in groundwater sample taken in Fujian province (Table 2). Nevertheless, some samples contained higher concentrations of 226 Ra were observed in groundwater samples taken in Egypt [8] and Yemen [9] and Serbia [10]. However, there is a report of 226 Ra monitoring in groundwater samples taken in Roi-Et Province, northeastern part of Thailand [14].…”
