Abstract
Bu çalışmada, Siirt bölgesinin farklı alanlarından toplanan tuzlu sularda toplam α ve toplam β seviyeleri ve metal içerikleri PIC-MPC-9604 model α/β sayım sistemi ve dalga boyu dağılımlı X-ışını floresans spektrometresi ile ölçüldü ve değerlendirildi. Örneklerde, minimum ölçülebilir derişimler (MÖD) (0,11 – 0,20 Bq L-1) ile toplam α aktivite derişimleri (0,44 – 0,62 Bq L-1) ve MÖD (0,10 – 0,17 Bq L-1) ile toplam β aktivite derişimleri (0,93 – 1,67 Bq L-1) olarak tayin edilmiştir. Tuzlu sularda bulunan radyoaktivite ve element konsantrasyonlarının karşılaştırılması Dünya Sağlık Örgütü (WHO), Birleşik Devletler Çevre Koruma Ajansı (USEPA) ve Türk Standartları (TS) tarafından bildirilen değerleri ile daha önce yayınlanan çalışmalarda raporlanan değerler kullanılarak yapılmıştır. Tuzlu suları, metal derişimleri ve aktivite seviyeleri açısından kategorize etmek için ana bileşen ve küme analizleri kullanılmıştır.
Bulunan üç ana bileşen, verilerdeki toplam değişkenin yaklaşık % 90,4'ü olmuştur.
In this study, gross α and gross β radioactivity concentrations and metal contents in saline waters collected from different areas of Siirt region were measured and evaluated by using PICMPC-9604 model α/β counting system and wavelength dispersive X-ray fluorescence spectrometry. The gross α activity concentrations (0.44 - 0.62 Bq L-1) with minimum detectable concentrations (MDC) (0.11 - 0.20 Bq L-1) and gross β activity concentrations (0.93 - 1.67 Bq L -1) with MDC (0.10 - 0.17 Bq L-1) in samples were determined. Comparison of radioactivity and element concentrations found in the saline waters were made with the reported values from World Health Organization (WHO), the United States Environmental Protection Agency (USEPA), the Turkish Standards (TS) and values reported in previous studies. Principal component and cluster analyses were utilized to categorize the saline waters in terms of metal and activity concentrations. Three principal components found were nearly 90.4% of whole variance for the data.
