In this study, radiological distribution of gross alpha, gross beta, (226)Ra, (232)Th, (40)K, and (137)Cs for a total of 40 natural spring water samples obtained from seven cities of the Eastern Black Sea Region was determined by artificial neural network (ANN) method. In the ANN method employed, the backpropagation algorithm, which estimates the backpropagation of the errors and results, was used. In the structure of ANN, five input parameters (latitude, longitude, altitude, major soil groups, and rainfall) were used for natural radionuclides and four input parameters (latitude, longitude, altitude, and rainfall) were used for artificial radionuclides, respectively. In addition, 75 % of the total data were used as the data of training and 25 % of them were used as test data in order to reveal the structure of each radionuclide. It has been seen that the results obtained explain the radiographic structure of the region very well. Spatial interpolation maps covering the whole region were created for each radionuclide including spots not measured by using these results. It has been determined that artificial neural network method can be used for mapping the spatial distribution of radioactivity with this study, which is conducted for the first time for the Black Sea Region.

“…Thus, since the microorganisms in drinking water could lead to risks that could threaten human health due to long exposure to radiation, albeit in small doses, the quality of drinking water should be monitored continuously. Therefore, this necessitates the measurement, monitoring and limitation of radioactivity in drinking water and ground and surface waters, which are used as drinking water sources (El-Arabi, 2007;Janković et al, 2012;Chau and Michalec, 2009;El-Mageed et al, 2013;Kobya et al, 2010;UNSCEAR, 2000).…”

“…In addition, radon concentration studies were performed in home and outside air environments (Özen et al, 2018). Also, radionuclide activity measurements, total alpha and total beta analyzes were performed in drinking and natural spring waters (Kobya et al, 2010;Kobya et al, 2011) in the same Province.…”

In the present study, radionuclide and radon concentrations were measured in drinking water samples collected in Andon springs and Rize Andon Drinking Water Treatment Facility located at Rize province in Eastern Black Sea Region in Turkey and radionuclide concentrations were measured in soil samples collected in the same regions. Radionuclide activity concentrations in soil and drinking water samples were measured with gamma ray spectrometry, and 238 U, 232 Th, 40 K and 137 C activity concentrations were determined. Annual effective dose equivalents were calculated based on the measured results. Radon concentration measurements for the drinking water samples collected in the region were conducted with a radon gas analyzer (Alpha Guard PQ 2000PRQ). All measured radon gas levels and radionuclide values were found to be among the limit values recommended by international organizations. Andon Bölgesi'nden Alınan Toprak ve İçme Suyu Örneklerinde RadyoaktiviteDüzeyleri (Rize İli, Türkiye) Öz Türkiye'nin Doğu Karadeniz Bölgesi'ndeki Rize iline bağlı Andon içmesi ve aynı bölgede bulunan "Rize Andon İçme Suyu Arıtma Tesisinden" alınan içme suyu örneklerinde ve bu kaynakların çevresinden toplanan toprak örneklerinde radyoaktivite ve radon konsantrasyonları ölçülmüştür. Toprak ve içme suyu örneklerinde radyonüklid aktivite konsantrasyonları gama ışını spektrometresi ile ölçülüp, 238 U, 232 Th, 40 K ve 137 C aktivite konsantrasyonları belirlenmiştir. Ölçüm sonuçları dikkate alınarak yıllık etkili doz eşdeğerleri hesaplanmıştır. Bu bölgeden toplanan içme sularındaki Radon konsantrasyonunun ölçümü, radon gazı analiz cihazı (Alpha Guard PQ 2000PRQ) kullanılarak gerçekleştirilmiştir. Ölçülen tüm radon gazı seviyeleri ve radyonüklid değerlerinin uluslararası kuruluşlar tarafından önerilen sınır değerler arasında olduğu bulunmuştur.

This study has evaluated the levels of natural radionuclides and chemical components of mineral waters in the Eastern Black Sea Region (Turkey). The mean activity concentrations of (226)Ra, (232)Th, (137)Cs, (40)K, gross alpha and gross beta were found as 129, 33, 28, 714, 125 and 170 mBq L(-1), respectively. Due to consumption of mineral waters, the radiological impact of them on the inhabitants was calculated by taking the annual intake into account through ingestion of aforementioned radionuclides. The estimated effective doses from mineral water were found to be 13.20 μSv year(-1) ((226)Ra), 2.74 μSv year(-1) ((232)Th), 0.13 μSv year(-1) ((137)Cs) and 1.62 μSv year(-1) ((40)K). The overall contribution of these radionuclides to the committed effective dose from a year's consumption of mineral water in the region is therefore estimated to be only 17.69%, which is in concordance with the recommended WHO value (100 μSv year(-1)). The chemical analysis results showed that these waters contain Na, Al, P, Cl, K, Ca, V, Mn, Fe, Ni, Cu and Zn elements. These values were evaluated and compared with the internationally verified values. This study provides important information for consumers and authorities because of their internal radiochemical exposure risk from mineral water intake.
