Radiological and chemical monitoring of Dikili geothermal waters, Western Turkey

Measurements of Radon Content in the Thermal Waters in Sakarya

“…As can be seen from Table, radon levels recorded in the present study are relatively low when they are compared to corresponding radon activity measured in Italy [5], in Venezuela [8], in Iran [9], in Serbia [10] and also is lower than those reported from other parts of Turkey namely Dikili [12] and Bursa [14], but comparable to radon levels reported from Yalova [11] and from West Anatolia [13]. It is interesting to note that both of Yalova and Sakarya lie on North Anatolian Faulth Zone.…”

“…However, a very high level of radon in ingested drinking water can also leads to a significant risk of stomach cancer [7]. Because of its potential health hazard, radon level in thermal waters and associated effective doses have been documented in many regions worldwide for decades [5,[8][9][10] and also led to extensive surveys in Turkey [11][12][13][14][15]. In the present study, the radon contents of thermal waters located in Kuzuluk and Taraklı regions of Sakarya were measured and the results were evaluated according to international recommendations.…”

Radon concentration in drinking water sources of the region adjacent to a tectonically active Karak Thrust, southern Kohat Plateau, Khyber Pakhtunkhwa, Pakistan

“…However, the mean radon concentration and the total mean annual effective dose of the drinking water samples of this study are higher than the mean radon concentration and the total annual effective dose of 2.07 Bq l -1 and 0.0076 mSv a -1 , respectively, in the drinking water samples from the Varahi, command area of India [33]. The mean radon concentration of 9.4 Bq l -1 in the drinking water samples from the studied area is slightly higher than the mean radon concentration of 8.2 Bq -1 in the drinking water samples from Dikili region of Turkey [34], mean radon concentration of 6.8 Bq -1 in the drinking water samples from Milano area of Italy [35], and mean radon concentration of 6.1 Bq -1 in the drinking water samples from Kutahya area of Turkey [36].…”

“…Our mean anural effective doses of 0.002 and 0.024 mSv a -1 due to ingestion and inhalation from radon in water are similar (within error limit) to the mean annual effective doses of 0.002 and 0.025 mSv a -1 of UNSCEAR due to ingestion and inhalation, respectively. In Table 3 radon concentrations and mean annual effective doses due to ingestion and inhalation from the drinking water sources of the study area have been compared with the results of similar studies conducted in the different regions and countries [29][30][31][32][33][34][35][36][37]. The mean radon concentration of 9.4 ± 0.4 Bq l -1 in the water samples of this study is higher than the mean radon concentration of 4.38 ± 0.44 Bq l -1 in drinking water samples of Murre area, Pakistan [29].…”
