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

Öz

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.
