Abstract

Bu çalışmada, topraktan ayçiçeğine radyonüklid transferini araştırmak için Türkiye’de Kırklareli ilinde 20 farklı tarım arazisinde toprak ve ayçiçeği örneklemesi yapılmıştır. Toprak örneklerinde bulunan 40K ve ayçiçeği örneklerinde bulunan 226Ra, 232Th, 40K ve 137Cs radyonüklid aktivite konsantrasyonları HPGe gama spektrometre sistemi kullanılarak ölçülmüştür. Ayçiçeği örneklerinde bulunan 40K radyonüklid aktivite konsantrasyonu 255,86±21,78 ile 426,51±29,42 Bq kg-1 aralığında ölçülmüş, fakat 226Ra, 232Th ve 137Cs aktivite konsantrasyonları ihmal edilebilir seviyelerde bulunmuştur. 40K radyonüklidinin topraktan ayçiçeğine transfer faktörleri hesaplanmış ve 0,34-1,17 aralığında bulunmuştur. Ayrıca, elde edilen ortalama transfer faktörü değeri Dünya’da yapılan diğer çalışmalarla kıyaslanmıştır.
