Determination of natural radioactivity levels of some concretes and mineral admixtures in Turkey
Baltaş, Hasan; Kiriş, Erkan; Ustabaş, İlker; Yılmaz, Esra; Şirin, Murat; Kuloğlu, Emrah; Güneş, Banu Erdoğan (Asian Journal of Chemistry, 2014)Nine concrete samples with or without mineral admixtures have been analyzed for their naturally occurring radionuclide of Ra-226, Th-232 and K-40 using HPGe gamma spectrometry. Also, concrete raw materials such as aggregate, ... -
Gamma ray and neutron shielding properties of some concrete materials
Yılmaz, Erol; Baltaş, Hasan; Kırış, Erkan; Ustabaş, İlker; Çevik, Uğur; El-Khayatt, A.M. (Elsevier, 2011)Shielding of gamma-rays and neutrons by 12 concrete samples with and without mineral additives has been studied. The total mass attenuation and linear attenuation coefficients, half-value thicknesses, effective atomic ... -
