Konya-Ilgın-Çavuşçu Linyit Maden Yatağında Dış Ortam Gama Doz Oranlarının Belirlenmesi

Abstract

Bu çalışmada Konya’nın Ilgın ilçesindeki linyit kömür yatağındaki doğal olarak oluşmuş radyoaktif çekirdeklerden kaynaklanan karasal gama doz oranları belirlenmiştir. Ölçümler, toprak yüzeyinin üstünde ve NaI(Tl) gama-ışın detektörü kullanılarak gerçekleştirilmiştir. Ayrıca, ölçülen bu karasal gama doz oranları kullanılarak her bir ölçüm noktası için ortalama harici yıllık etkin dozlar hesaplanmıştır.

Keywords

Assessment of Outdoor Terrestrial Gamma Dose Rates in the Konya-Ilgın-Çavuşçu Lignite Deposit (Turkey)

Abstract

This study assesses the terrestrial gamma radiation dose rates from the naturally occurring radionuclides in the lignite coalfield of Ilgın district of Konya. The measurements were performed above the surface soil using NaI(Tl) gamma-ray detector. The average external annual effective doseswere also calculated using these terrestrial gamma radiation dose rates for each measurement location.

Keywords
