Kırklareli Mermerinin Gama Radyasyonu Zayıflatma Katsayılarının Deneysel Olarak İncelenmesi

Kırklareli İli mermer örneği için toplam lineer zayıflatma ve kütle zayıflatma katsayıları, yarı-değer ve onda bir-değer kalınlıkları, farklı gama enerjileri kullanılarak araştırılmıştır. Üç faklı gama enerjisi; biri Cs-137 radyoizotopudan 661.7 keV, diğer ikisi Co-60 radyoizotopudan 1173.2 keV ve 1332.5 keV, olmak üzere kullanılmıştır. Ölçümler gama sintilasyon detektörü NaI(Tl) kullanılarak gerçekleştirildi. Ölçümlerden ve XCOM bilgisayar kodundan elde edilen sonuçlar mukayese edilip, literatür ile de karşılaştırılmıştır. Mermer disklerin ölçümü ile elde edilen sonuçlar, kireç tozu tabletlerinin ölçümünden elde edilen sonuçlar ile de mukayese edildi.

Experimental Investigation of Gamma Radiation Attenuation Coefficients for Kırklareli Marble

The total linear and mass attenuation coefficients, half-value andtenth-value thickness of marble samples from Kırklareli Province have beeninvestigated using different gamma ray energies. Three different gamma rayenergies one at 661.7 keV from Cs-137 and others at 1173.2 and at 1332.5keV from Co-60 have been used. The measurements were carried out using agamma spectrometer containing a NaI(Tl) sintilation detector. Comparisonbetween the results from measurements and from computer code of XCOMhas also been performed with the results available in literature. Themeasurement results obtained from marble disks and tablets of limestonepowder were also matched.
