Abstract
Bu çalışmada, Bafra Kızılırmak Deltası'ndan toplanan toprak örneklerinde, gama spektrometre sistemi kullanılarak doğal radyoaktivite seviyeleri belirlendi. Toplanan 30 adet toprak numunesindeki doğal gama aktiviteleri NaI(Tl) dedektörlü gama spektrometresi kullanılarak ölçüldü.Toprak numunelerinde NaI(Tl) dedektörlü sistem kullanılarak elde edilen gama ışını spektrumlarından 238U, 232Th, 40K ve 137Cs radyoaktivitelerinin ortalama değerleri sırasıyla, 37,24 ± 3,75 Bq/kg, 32,57 ± 2,17 Bq/kg, 412,99 ± 11,91 Bq/kg, 364,65±22,25 Bq/kg ve 13,76 ± 1,57 Bq/kg olarak ölçüldü.Elde edilen bu değerler Türkiye ve dünya ortalama değerleriyle karşılaştırıldı.
In this study, natural gamma radioactivity levels were determined by gamma ray spectrometry method in the soil samples which collected from Bafra Kizilirmak Delta. Natural radioactivity levels of total 30 soil samples were measured with gamma spectrometry system which has NaI(Tl) detector.In the analysis carried out with NaI(Tl) gamma spectrometry system, the average activity concentrations of 238U, 232Th, 40K and 137Cs were determined as 37,24 ± 3,75 Bq/kg, 32,57 ± 2,17 Bq/kg, 412,99 ± 11,91 Bq/kg and 13,76 ± 1,57 Bq/kg, respectively.The obtained results are compared with the Turkey and world average.
