Balıkesir&Çanakkale Bölgesi, Edremit&Ayvacık Sınırlarındaki Kazdağı Köylerinde Havadaki Yıllık Gama Dozlarını Kullanarak Kanser Risk Hesabı

Öz

Çalışmada Edremit ve Ayvacık ilçeleri sınırlarında bulunan Kazdağı Köylerinde, öncelikle havadaki gama doz hızlarının ölçülmesi hedeflenmiştir Turistik bölge olan Kazdağında özellikle yaz sezonunda oldukça yoğun nüfus ağırlanmaktadır Bu suretle sadece yöre insanını değil aynı zamanda ziyaretçilerini de ilgilendirmektedir. Toplamda 75 farklı ölçüm noktasında gama doz hızları alınmıştır. Ortalama doz hızı 162.04 nGyhr^-1 ve yıllık doz ise 198.66 μSv hesaplanmıştır. Bu değerler yardımıyla kanser risk hesabı yapılmış ve 6.95x10⁻⁴ bulunmuştur. Her üç değer de, literatürde geçen diğer ulusal/uluslararası değerlerle mukayese edilmiştir. Yine UNSCEAR değerleriyle de nisbeti görülmektedir. Bu çalışma, ileride yapılacak benzer/bölgesel araştırmalara referans olabilecektir. Yine muhtemel bir radyoaktif sızıntı sonrasında aynı ölçüm noktalarında yeniden alınacak değerlerle mukayesesi, sızıntı boyutu hakkında detaylı bilgi verebilecektir.

Cancer Risk Determination for IDA villages by using Annual Gamma Doses in Air

Abstract

Main focus of this study is to measure outdoor gamma dose rates for IDA villages around Edremit and Ayvacık districts. This touristy location, is so closest to seismic zone and thermal water sources, has lodgings huge human population especially in summer season. It is important that not only local people but also for visitors, too. Total measurings on 75 different stations, were obtained and then calculated the annual dose. Average dose rate was calculated to 162.04 nGyhr-1 . Annual dose is 198.66 μSv. On the other hand, access life time cancer risk was calculated for studing area. It is equal to 6.95x10−4 . These values were compared with the World’s references (UNSCEAR) and assumed. . This study would be referenced for futher works, besides it will be usefull while comparing with the different studies for IDA which, will be completed in the future, for example after a radioactive pollution, such as a reactor leakage, weapon’s effect, etc., too.
