Bu çalışmada, bazı dielektrik malzemelerin (kehribar, pleksiglas, organik cam, kuvars, bakalit, NaCl, porselen ve mermer) transmisyon faktörleri (TF), lineer soğurma katsayıları (μ), kütle soğurma katsayıları (μ⁄ρ), ortalama serbest yol ("λ" ), radyasyondan korunma verimliliği (RPE), yarı kalınlık değeri (HVL) ve onda bir kalınlık değeri (TVL) ölçülmüştür. Soğurma ölçümü EDXRFS (Enerji Ayrımlı X-ışını Flöresans Spektrometresi) ile yapılmıştır. Çalışmanın amacı, teknolojik öneme sahip bu dielektrik malzemeler üzerinde yapılacak ölçümler ve hesaplamalar sayesinde yeni kullanım alanları oluşturulmasıdır. Elde edilen sonuçlara göre kehribar en iyi gama ışını zırhlama malzemesiyken, kuvars gama ışını zırhlaması için uygun değildir.

An Experimental Examination on the Determination of γ-ray Shielding Parameters of Some Dielectric Materials

Öz

In this study, γ-ray shielding parameters (transmission factors (TF), linear attenuation coefficients (μ), mass attenuation coefficients (μ⁄ρ), mean free path ("λ" ), radiation protection efficiency (RPE), half-value layer (HVL), and tenth value layer (TVL)) were measured of some dielectric materials (amber, plexiglass, organic glass, quartz, bakelite, NaCl, porcelain, and marble). The absorption measurements were done by EDXRFS (Energy Dispersive X-ray Fluorescence Spectrometer). The study aims to create new areas of use thanks to the measurements and calculations to be made on these technologically important dielectric materials. According to the results obtained, amber is the best gamma ray shielding material, while quartz is not suitable for gamma ray shielding.
