Ayrıca hesaplamalardan elde edilen verilerin yardımı ile alfa ve beta aktiviteleri için tanımlayıcı haritalar üretilmiştir. Çalışma alanını tanımlayacak bir şekilde 102 istasyondan su örnekleri alınmış ve bunların rastgele seçilmiş 50% si (51) model için kullanılırken geriye kalan %50 si (51) model sonundaki doğrulama testi için kullanılmıştır. Sırasıyla alfa ve beta aktiviteleri için maksimum ölçüm değeri, 0.771 Bq/L, ve 0.808 Bq/L ve minimum değerleri 0.005 Bq/L ve 0.0013 Bq/L olarak bulunmuştur. Çalışmanın sonucunda universal kriging yönteminin ara değer tahmininde ordinary kriging yönteminden daha iyi olduğu belirlenmiş ve oluşturulan haritalarda küçük alanlı yerel değişimlerin daha iyi gözlendiği görülmüştür. Simülasyon ve tahmin haritaları karşılaştırıldığında sulardaki toplam alfa ve betanın dağılımının iyi bir şekilde temsil edildiği belirlenmiştir. N2 - This study figures out the estimated values of total beta and alpha activities for non-sampled points in the study area of natural spring water in Artvin province by using geostatistical prediction methods (ordinary kriging and universal kriging). Water samples were taken from 102 stations which describes the study area and randomly chosen 50% of the samples (51) were used for the modelling and the other 50% were used for the validation test at the end of the model. The maximum measurement values were found to be 0.771 Bq/L and 0.808 Bq/L and minimum values were 0.005 Bq/L and 0.013 Bq/L, respectively. In addition, both gross alpha and gross beta distributions were specified by using simulation method (conditional gauss simulation). With the help of acquired data from prediction and simulation, descriptive maps were drawn for gross alpha and gross beta activities. Comparing simulation and prediction maps, it is specified that gross alpha and gross beta distribution in water was represented efficiently. At the end of the study, it was seen that universal kriging method was better than ordinary kriging method for interpolated estimation value CR - Kobya Y, Taşkın H, Yeşilkanat CM, et al.
