Investigation of Nanoparticle Effect on Radiation Shielding Property Using Monte Carlo Method
Abstract
Investigation of Nanoparticle Effect on Radiation Shielding Property
Using Monte Carlo Method
Radiation protection and choice of appropriate materials in the areas of medical and industrial applications has become one of the major research topics. In this study, the increment in mass attenuation coefficients by doping of nano-sized barite (BaSO4) into the lead (Pb) have been investigated. The validation of generated MCNPX simulation geometry is provided by comparison with the previous experimental and theoretical studies. This generated geometry was used for the definition of nano-BaSO4 into lead material and calculations. It was found that nano-BaSO4 doped lead increased the amount of radiation absorbed in the material inside and as a result of which affected the radiation attenuation properties of material. This study also showed that MCNPX is an effective code on nano size studies and standarised geometry can be useful for further investigations.
Radyasyon Zırhlama Özelliğinde Nanoparçacık Etkisinin Monte Carlo Metodu Kullanarak İncelenmesi
Radyasyondan korunma ve uygun malzeme seçimi medikal ve endüstriyel radyasyonun kullanıldığı alanlarda başlıca araştırma konularından bir tanesi haline gelmiştir. Bu çalışmada, kurşun (Pb) içerisine nano boyutlarda barit (BaSO4) katkısı yapılarak kütle zayıflatma katsayısında meydana getirdiği artış incelenmiştir. Oluşturulan MCNPX simülasyon geometrisinin validasyonu önceki deneysel ve teorik ölçümler ile sağlanmıştır. Oluşturulan bu geometri nano BaSO4 parçacıklarının kurşun malzeme içerisine tanımlanmasında ve hesaplamalarda kullanılmıştır. Sonuç olarak nano boyutlarda kurşun içerisine katkılanan BaSO4 nanoparçacıklarıkurşunun kütle zayıflatma katsayısında bir artışa sebep olmuş, malzeme içerinde soğurulan radyasyon miktarı artmış ve malzemenin radyasyonun zayıflatma özelliklerini etkilemiştir. Bu çalışma ayrıca MCNPX kodunun nano boyutlardaki çalışmalarda etkili bir program olduğunu ve standartize edilen bu geometrinin gelecek çalışmalar için kullanılabilirliğini göstermiştir.
