İstanbul Boğazı’nda 137Cs Konsantrasyonun Belirlenmesi

Öz

Tıbbi atıklar, endüstriyel faaliyetler, nükleer testler ve nükleer reaktörlerde meydana gelen kazalardan kaynaklanan antropojenik radyonüklidler, çevre üzerinde ciddi etkilere neden olabilecek kirlilik kaynaklarıdır. Çernobil kazasından sonra birçok antropojenik radyonüklitin Karadeniz'e girdiği bilinmektedir. Türkiye'nin kuzey kesimindeki topraklar 1986'daki Çernobil serpintisi ile kirlenmiştir. Bu çalışmada, toprak örneklerinde ¹³⁷Cs aktivite konsantrasyonları ölçülmüştür. İstanbul Boğazı Anadolu yakasının farklı lokasyonlarından toplanan yüzey toprağındaki antropojenik (¹³⁷Cs) radyonüklid aktivitesinin konsantrasyonları, HPGe dedektörlü yüksek çözünürlüklü gama spektrometresi ile analiz edilmiştir.¹³⁷Csaktivite konsantrasyonları0.74±0.31 - 6.21±0.16 Bqkg^-1arasında değişmektedir.

Determination of 137Cs Concentration in Anatolian side of the Bosphorus

Abstract

Anthropogenic radionuclides resulting from accidents in nuclear reactors, nuclear tests, industrial activities and medical wastes are sources of pollution that can cause serious impacts on environment. It is well known that many anthropogenic radionuclides entered the Black Sea after the Chernobyl power plant accident. Soil in especially the northern part of Turkey were contaminated by the Chernobyl fallout of 1986. In the present study, the activity concentrations of 137Cs in the soil samples measured. The activity concentrations of the anthropogenic (137Cs) radionuclide in surface soil samples collected from different locations in Anatolian Side (Bosphorus) were analyzed by the high-resolution gamma spectrometer with HPGe detector. The activity concentrations of137Cs ranged from 0.74±0.31 - 6.21±0.16 Bqkg-1.
