Abstract

Bu çalışmada, Şile-İstanbul' da bulunan
Ağlayankaya plajından toplanan kumların doğal radyoaktivite seviyelerini
belirlemek için
226Ra, 232Th ve 40K konsantrasyonları gama spektrometre sistemi ile ölçülmüştür. Kum
numunelerindeki 226Ra, 232Th ve 40K aktivite
konsantrasyonları, sırasıyla 35.170, 31.637 ve 382.284 Bq / kg ortalamaları ile
27.368 ila 41.773, 22.147 ila 40.125 ve 293.667 ila 463.582 Bq / kg
arasındadır. Ölçümler sonucunda elde edilen 226Ra, 232Th
ve 40K aktivite konsantrasyonları kullanılarak soğurulan gama doz
hızı, yıllık etkin doz eşdeğeri, radyum eşdeğer aktivitesi, iç tehlike endeksi
ve dış tehlike endeksi değerleri hesaplanmıştır. Bunların yanı sıra, radyasyon
maruziyetinin bir sonucu olan yaşam boyu kanser riski (LCR) hesaplanmıştır.
Elde edilen tüm sonuçlar uluslararası kuruluşlar tarafından önerilen limit
değerler ile karşılaştırılmıştır. Bu sonuçlara göre, hem radyolojik zarar
indeksleri açısından hem de doz parametreleri açısından hiç bir zarar teşkil
etmediği sonucuna varılabilir.

Abstract

In this study, 226Ra, 232Th and 40K concentrations were measured by gamma spectrometry system to determine the natural radioactivity levels of sand collected from Aglayankaya beach in Şile-Istanbul. The activity concentrations of 226Ra, 232Th and 40K in the sand samples are between 27.368 and 41.773, 22.147 to 40.125 and 293.667 to 463.582 Bq / kg, respectively, with averages of 35.170, 31.637 and 382.284 Bq / kg. The absorbed dose rate, annual effective dose equivalent, radium equivalent activity, internal hazard index and external hazard index values were calculated using the 226Ra, 232Th, 40K activity concentrations obtained as a result of the measurements. In addition, lifetime cancer risk (LCR), which is a consequence of radiation exposure, has been calculated. All the results obtained are compared with the limit values recommended by international organizations. According to these results, it can be concluded that there
is no harm in terms of both radiological damage indices and dose parameters.
