Andon Bölgesi'nden Alınan Toprak ve İçme Suyu Örneklerinde Radyoaktivite Düzeyleri (Rize İli, Türkiye)

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, 238U, 232Th, 40K ve 137C 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.

Radioactivity Levels in Soil And Drinking Water Samples Collected from Andon Region (Rize Province, Turkey)

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 238U, 232Th, 40K and 137C 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.
