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.

Anahtar Kelimeler

Gama doz oranı, Ilgın linyit yatağı, karasal radyasyon

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

Öz

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.

Anahtar Kelimeler

Gamma dose rate, Ilgın lignite deposit, terrestrial radiation
