Investigation of Polylactic Acid (PLA) / Titanium Carbide (TiC) Nanocomposite Films Gamma Ray Shielding Properties
Abstract
In this study, gamma rays absorption properties of Polylactic Acid (PLA)/Titanium Carbide (TiC) nanocomposite films produced by containing 5% TiC were investigated. In applications where radioactive sources such as industry and medical are used, protection from the harmful effects of radiation is very important. Researches on materials to be used in shielding as an alternative to lead are becoming widespread. Comfortable, easily shaped, thin, durable, non-toxic to the environment and the user are the features sought in an ideal shield materials. For this purpose, the gamma ray absorption properties of the PLA/TiC nanocomposite material and its effect on radiation shielding were investigated. The linear attenuation coefficient value of the sample with different thicknesses was obtained with the NaI(TI) scintillation detector. A monochromatic gamma source, Cs-137 gamma radioisotope with 661.62 keV energy was used as the gamma radiation source. To determine the gamma ray shielding ability of materials Half value layer (HVL), tenth value layer (TVL) and radiation shielding efficiency (RPE) parameters of the material were calculated.

Abstract
Bu çalışmada, %5 TiC içeren Polilaktik Asit (PLA)/Titanyum Karbür (TiC) nanokompozit filmlerin gama ışınları absorpsiyon özellikleri incelenmiştir. Özellikle endüstri ve medikal gibi radyoaktif kaynakların kullanıldığı uygulamalarda radyasyonun zararlı etkilerinden korunma oldukça önemlidir. Kurşuna alternatif olarak zırhlamada kullanılacak malzeme araştırmaları yaygınlaşmaktadır. Kolay şekil alabilen, ince, konforlu, dayanıklı, toksik açıdan çevreye ve kullanıcıya zarar vermemesi ideal bir zırhlayıcı malzemede aranan özelliklerdir. Bu amaçla, üretilen PLA/TiC nanokompozit malzemesinin gama ışınlarını soğurma özellikleri ve radyasyon zırhlamasındaki etkisi araştırılmıştır. Gama radyasyon kaynağı olarak monokromatik bir gama kaynağı olan 661.62 keV enerjili 137Cs gama radyoizotopu kullanıldı. NaI(TI) sintilayon dedektörü ile farklı kalınlıklardaki numunenin soğurma katsayısı değeri elde edildi. Malzemelerin gama ışını zırhlama kabiliyetini belirlemek için, malzemenin Yarı değer katmanı (HVL), onuncu değer katmanı (TVL) ve radyasyon koruma verimliliği (RPE) parametreleri hesaplanmıştır.
