In this study the radiation dose absorbed from the surrounding area was determined for a polymineral ceramic sample that was found by an archeological excavation. Determination of equivalent dose is one of the critical points for luminescence dating researches. The sample used was prepared according to the polymeric content and fine grain technique without decomposing into minerals such as feldspar, quartz. The pre-heating temperature for the sample was determined as a result of experimental procedures. The prepared sample was preheated at 200 ° C for 12 minutes. A different method was used for the first time in our study, which is different from the methods commonly used for determining the equivalent dose in geological or archaeological samples. The details and observed advantages of this method are mentioned in our study. The equivalent dose values obtained range from 5,17 ± 0,09 to 7,06 ± 0,29 Gy.

Bu çalýþmada arkeolojik kazýyla çýkarýlmýþ polimineral içerikli bir seramik numunenin gömü boyunca çevreden soðurduðu radyasyon dozu (eþdeðer doz) bulunmuþtur. Eþdeðer dozun belirlenmesi lüminesans yaþ tayini araþtýrmalarýnda önemlidir. Kullanýlan numune feldispat, kuvars gibi minerallere ayrýþtýrýlmadan polimineral içerikli ve ince tanecik tekniðine uygun olarak hazýrlanmýþtýr. Kullanýlan numune için ön ýsýtma sýcaklýðý deneysel iþlemler sonucunda belirlenmiþtir. Hazýrlanan numune 200 0C’de 12dakika süreyle önýsýtmaya tutulmuþtur. Jeolojik veya arkeolojik numunelerde eþdeðer dozun belirlenmesi için sýklýkla kullanýlan yöntemlerden farklý bir yöntem çalýþmamýzda ilk defa kullanýlmýþtýr. Çalýþmamýzda bu yöntemin ayrýntýlarýndan ve gözlenen avantajlarýndan bahsedilmiþtir. Elde edilen eþdeðer doz deðerleri 5,17±0,09 ile 7,06±0,29 Gy arasýnda deðiþmektedir.
