Optiksel Uyarılmayla Lüminesans Yöntemi Kullanılarak Kuvarsit Numunesinin Dozimetik Özelliğinin İncelenmesi
Abstract
Bu çalışma Koçyazı formasyonundan alınan kuvarsit numunesinin optik uyarmalı lüminesans (OSL) yöntemi kullanılarak elde edilen doz-cevap ve tekrarlanabilirlik deneylerinin sonuçlarını içermektedir. Çalışmada doza bağlı OSL ölçümleri 1-1100 Gy arasında 13 farklı doz değeri için yürütüldü. OSL sinyal şiddetinin doza karşı davranışı incelendiğinde, 1 ile 600 Gy aralığında lineer bir davranışa sahip olduğu gözlendi. Ancak, dozimetrik malzeme olarak değerlendirilebilmesi için önemli testlerden biri olan tekrar kullanılabilirlik testinin sonuçları incelendiğinde 4. çevrimden sonra sınır olan %5 değerini aştığı görüldü.

Abstract
This study includes the results of dose-response and reusability experiments obtained by using optically stimulated luminescence (OSL) method of quartzite sample taken from the Koçyazı formation. In this study, dose-response OSL measurements were carried out for 13 different dose values between 1 -1100 Gy. When the behavior of the OSL signal intensity against the dose was examined, it was observed that the sample exhibited a linear behavior in the range of 1 to 600 Gy. However, when the results of the reusability test, which is one of the important tests to be evaluated as a dosimetric material, were examined, it was seen that it exceeded the limit of 5% after the 4th cycle.
