Özellikle taş, toprak, kaya gibi çevresel örneklerin doğal yapılarında farklı miktarlarda doğal radyonüklidler bulunmaktadır. Bu çevresel örneklerin doğal radyoaktivite seviyelerinin belirlenmesi çevrenın korunması ve insan sağlığı açısından önemlidir. Bu çalışmada, Basra petrol sahasındaki atık olarak ortaya çıkan yağla karışmış olan toprak örneklerinde Uranyum-238, Toryum-232 ve potasyum-40 doğal radyonüklidlerin aktivite konsantrasyonları ölçülmüştür. Bu ölçümler Süleyman Demirel Üniversitesi Fizik Bölümünde bulunan NaI(Tl) dedektörlü gama ışını spektrometresi kullanılarak yapılmıştır. Ölçülen aktivite konsantrasyonları kullanılarak, özellikle bu alanlarda çalışan işçilerin maruz kalacağı radyolojik tehlike seviyeleri belirlenmiştir. Elde edilen tüm sonuçlar tavsiye edilen limit değerler ile karşılaştırılmıştır.

Natural radionuclide content and radiological hazard levels of waste soil-oil mixture in the Basra oil field

Öz

There are different amounts of natural radionuclides in the natural structures of environmental samples such as stone, soil and rock. Determining the natural radioactivity levels of these environmental samples is important for the protection of the environment and human health. In this study, the activity concentrations of Uranium-238, Thorium-232 and potassium-40 natural radionuclides were measured in soil samples mixed with oil that emerged as waste in the Basra oil field. These measurements were made using NaI (Tl) detector gamma ray spectrometry in Süleyman Demirel University Physics Department. Using the measured activity concentrations, the levels of radiological hazards to which especially workers working in these areas will be exposed were determined. All results obtained were compared with the recommended limit values.
