Abstract
Bu tecrübede Türkiye’de mevcut ve MTA tarafından temin edilebilen tabiî kalsiyum florür numunelerinin hepsi, termolüminesans personel dozimetresi elde edilmesi maksadıyla ayrı ayrı incelemeye tabi tutularak içlerinden uygun olanlar seçilmiştir. Bu incelemelerin yapılması maksadıyla toz haline getirilmiş olan CaF2 numuneleri çeşitli tane büyüklüklerine ayrılarak (80-140); (140- 180); (180-325) kılcal cam borular içerisinde 2-3 miligramlık dozimetreler hazırlanmıştır. Bütün deney boyunca aynı dozimetreler kullanılmıştır. Doz olarak (1 - 1000) R aralığı seçilmiş ve zaman zaman daha yüksek dozlarda denenmiştir. Seçilen en hassas üç numune ile toz metodu kullanılarak (fading) kaybolma deneyleri yapılmıştır.
Twenty types of natural CaF2 samples are investigated to find their dosimetric characters in order to obtain personal dosimeters. The samples are cleaned, ground and sized in mesh ranges of (80- 140); (140- 180) and (180-325), then furnaced at about 400°C for ten hours, (140- 180) meshes are used as dosimeter which packed in glass capillaries in few miligrams weight. Co-60 and Cs-137 γ rays are used for expesures in the range of (1 - 1000) R. Using powder method, three sensitive natural CaF2 samples named as blue, green, and mixed color are used in fading experiments for one month duration.
