Abstract

Bu çalışmada, Recep Tayyip Erdoğan Üniversitesi Zihni Derin Yerleşkesinden alınan 15 adet toprak örneğinde yüksek saflıkta bir germanyum dedektörü (HPGe) kullanılarak yapay (137Cs) ve doğal (226Ra, 232Th and 40K) radyonüklidlerin miktarları belirlenmiştir. 226Ra, 232Th, 40K ve 137Cs için aktivite değerleri sırasıyla 43.78 ile 62.58, 29.85 ile 41.61, 132.48 ile 346.44 ve 3.90 ile 202.94 Bq kg-1 arasında değişmiştir. UNSCEAR (2000) tarafından verilen dünya ortalama değerleri ile karşılaştırıldığında, toprak numuneleri için ortalama 226Ra, 232Th aktivite değerlerinin daha yüksek olduğu fark edilmiştir. 40K ve 137C için ortalama aktivite konsantrasyonlarının, UNSCEAR (2000) tarafından bildirilen dünya ortalama değerlerinden daha düşük olduğu gözlemlenmiştir. Bunun yanı sıra radyolojik tehlike indeksleri hesaplanarak bu indeksler uluslararası izin verilen değerlerle karşılaştırılmıştır. Yapılan bu araştırma, çalışma alanında toprak örneklerine maruz kalanlar açısından herhangi bir sağlık sorunu olmadığını göstermiştir.
