Buildup of gamma ray photons in flyash concretes: A study

Gamma-ray exposure build-up factors of some brick materials in the state of Punjab

“…The GP fitting formula is known to be accurate within the estimated uncertainty (< 5%), and Harima carried out an extensive historical review and reported the current gamma photon build-up factors and applications (Harima, 1993). Various researchers have investigated gamma-ray build-up factors in different materials fly-ash, concretes (Brar et al, 1994;Singh et al, 2010;Badiger, 2012a, 2012b), solvents (Parjit et al, 2008), polymers (Tejbir et al, 2010;, human tissues , soils & ceramic (Sandeep and Gurdeep, 2012;Jasbir et al, 2012;Tejbir et al, 2013), and fly ash (Sukhpal et al, 2010), which showed that GP fitting is a very useful method for estimation of exposure and energy absorption build-up factors.…”

Neutron shielding qualities and gamma ray buildup factors of concretes containing limonite ore

“…When gamma radiations have interacted with matter through Compton scattering, the energy of incident photon reduces and its direction also changes in the way that the results in creating scattered photons can be estimated by the buildup factor (Singh et al, 2010). The buildup factors have been widely studied by a few researchers (Küç ük, 2010;Singh et al, 2010;Manohara et al, 2010;Mann and Korkut, 2013;Kavaz et al, 2015;Singh et al, 2014aSingh et al, , 2014b. The buildup factors can be summarised by the following types:…”

Determination of Build-up Factors for Natural Black Obsidian Ores

“…Gama-ışını yığılma faktörleri konusu uzun süreden beri çok farklı materyaller üzerinde yaygın bir şekilde araştırılmaktadır. Bu bağlamda camlar (Sayyed et al 2017); barit, manyetit, limonit, hematit ve serpantin gibi çeşitli cevherler (Oto et al 2015); bazalt kaya örnekleri (Karabul et al 2015); dozimetrik malzemeler (Kurudirek, 2014); termolüminesans dozimetrik malzemeler (Manohara et al 2010, Kucuk et al 2013; topraklar (Dhillon et al 2012); seramikler (Singh et al 2013); çözücüler (Singh et al 2008); polimerler (Singh et al 2009); bazı bor bileşikleri (İçelli et al 2013) ve sıva betonları (Singh et al 2010) gibi faklı malzemelerde gama ışını yığılma faktörü ile ilgili başarılı çalışmalara literatürde rastlamak mümkündür. Bu araştırmaların çoğu radyasyon zırh ve koruma açısından yapılmıştır.…”
