Abstract

Many of the Thermoluminescence dosimeters (TLD) are used in different areas in order to measure “personnel dose equivalent”. It’s analyzes must be done by determining different dosimetric characteristics and specialty of TL the material. Obtaining data which supplies energy dependence of the detector response function for TL supplies is very difficult when experimental methods are used and can be measured with a large error value. It’s possible to get the detailed information when these detectors are modeled at computers. In this study, Li2B4O7 material which is used as “TLD” doped with Cu activator is modeled. Directional photon sources, in different distances TL dosimeter detector response function of the energy dependence has been found by the method of the MCNP Monte Carlo simulation method. In previous studies with the results obtained have been compared with the values obtained in this study

Abstract

Özet: Birçok Termolüminesanas Dozimetreleri (TLD) “personel doz eşdeğerini” ölçmek için farklı alanlarda kullanılmaktadır. TL malzemelerin değişik dozimetrik özelliklerinin ve karakteristiklerinin belirlenerek analizlerinin yapılması gerekmektedir. TL malzemeleri için dedektör cevap fonksiyonlarının enerjiye bağlılığını veren verileri elde etmek, deneysel yöntemler kullanıldığında oldukça güçtür ve büyük hata değerleriyle birlikte ölçülebilmektedir. Bu dedektörler, bilgisayar ortamında modellendiğinde ayrıntılı bilgi almak mümkün olabilmektedir. Bu çalışmada, Cu ile katkılanmış TLD olarak kullanılan Li2B4O7 malzemesi modellenmiştir. Yönlü foton kaynaklarından, farklı uzaklıklardaki TL dozimetrelerin dedektör cevap fonksiyonlarının enerjiye bağlılığı MCNP Monte Carlo simülasyon yöntemi ile bulunmuştur. Önceden yapılmış çalışmalardan elde edilen sonuçlar ile bu çalışmada elde edilen değerler karşılaştırılmıştır.
