Hatay ve Çevresinde Çevresel Gama Radyasyon Ölçümü

Hatay ve çevresinde havada yapılan ölçümlerde gama doz seviyelerini belirlemek için 183 farklı noktadayerden yaklaşık 1 m yükseklikte, cihazın belli bir dengeye gelebilmesi için 2 dakika beklendikten sonraölçümler alınmıştır. Ölçümler ucuna SPA-6 model plastik sintilasyon dedektörü bağlanmış EberlineSmart Portable (ESP-2) model bir cihaz kullanılarak yapılmıştır. Açık havada soğurulan gama doz oranı(ADR), gama doz kullanılarak radyo çekirdeklerin varlığına bağlı, havadaki yıllık etkin doz oranı (AEDE) veyaşam boyu kanser risk değerleri (YFKR) belirlendi. Hatay ve çevresinde dış gama dozu kullanılarak,gama doz ölçümlerinin aritmetik ortalaması 61,9 nGy/h, yıllık etkin doz eşdeğerinin ortalama değeri ise75,91 μSv/y olarak bulunmuştur. Bu çalışmada sunulan sonuçlar, Türkiye'nin farklı bölgelerinde yapılanbenzer çalışmaların sonuçları ve dünya ortalamaları ile karşılaştırılmıştır.

Measurement of Environmental Gamma Radiation in and Around The Hatay Province, Turkey

Measurements were taken after a waiting time of 2 minutes for the device to arrive at a certain balance at a height of about 1 m from 183 different points in order to determine the gamma dose levels by measurements made in the air in and around Hatay province. Measurements were made using an Eberline Smart Portable (ESP-2) model connected to the SPA-6 model plastic scintillation detector. Annual effective dose rate (AEDE) and lifetime cancer risk values (YFKR) were determined by using the gamma dose rate (ADR), gamma dose in the open air, and the presence of radionuclides. The arithmetic mean of the gamma dose measurements using external gamma doses in and around Hatay province was found to be 61.9 nGy /h and the mean value of the annual effective dose equivalent was 75,91 μSv /y. The results that are presented in this study has been compared with the results and the average of similar studies conducted in different regions of the world and Turkey.
