Abstract
Fukushima Nükleer santral Kazasının Anadolu Yarımadası üzerindeki etkileri üç farklı kaynak terim ile atmosferik dağılım modeli kullanılarak araştırılmıştır.. 131I parçacıklarının haca konsantrasyon değerleri 0.1 mBqm-3 ile 0.5 mBqm-3, 137Cs değerleri 0.01 mBq m-3 ile 0.05 mBqm-3, for 131I gaz değerleri 1 mBqm-3 ile 10 mBqm-3arasındadır. Bulunan değerler ölçüm değerleriyle kıyaslanmış ve bu değerler kullanılarak Anadolu Yarımadası için radyolojik doz değerleri hesaplanmıştır. Bulunan efektif doz değerleri Fukushima Nükleer Güç Santrali Kazasının etkilerinin Çernobil Nükleer Güç Santrali ile kıyaslandığında oldukça sınırlı olduğunu göstermektedir.
The effects of Fukushima Nuclear Power Plant accident over Anatolian Peninsula were investigated by using an atmospheric dispersion model with three different source terms. Air concentration amounts for 131I particles over Turkey were found between 0.1 mBqm-3 and 0.5 mBqm-3, for 137Cs between 0.01 mBq m-3 and 0.05 mBqm-3, and for 131I gas between 1 mBqm-3 and 10 mBqm-3. Results were compared with the measured values. The radiological doses were calculated over Anatolian Peninsula by using air concentration values simulated by atmospheric model. In addition the effective doses were found around nSv which shows that Fukushima Nuclear Power Plant accident has limited effects compared to Chernobyl Power Plant accident.
