AB  - Neutron particles are different, due to their nature of interacting directly with the atomic nucleus and making indirect ionization. In this study calcite containing and non-calcite containing concrete samples neutron shielding capabilities was compared with each other. CaCO3 (calcite) added concrete and pure concrete was experimentally compared against an isotropic Am-Be neutron source. Naturally, calcite containing concrete was in heavy form in comparison with pure concrete, means that the aim of these experiment is comparing neutron shielding properties of heavy and light concrete. In both samples, thickness of the samples was started with 2 cm and reach to 10 cm with 2 cm increases. The effect of thickness and the effect of material type on neutron shielding was investigated. According to the test results, pure concrete samples shows better shielding characteristics.

N2  - Nötron parçacıkları, atom çekirdeği ile doğrudan etkileşime girme ve dolaylı iyonizasyon yapma yapıları nedeniyle diğer radyasyon türlerinin oluşturduğu etkilerden farklı etkiler oluştururlar. Bu çalışmada kalsit içeren ve içermeyen beton numunelerin nötron zırhlama yetenekleri birbirleriyle karşılaştırılmıştır. CaCO3 (kalsit) katkılı beton ve saf beton deneysel olarak izotropik Am-Be nötron kaynağı karşısında karşılaştırılmıştır. Doğal olarak kalsit içeren betonun saf betona göre ağır formda olması, bu çalışmanın amacının ağır ve hafif betonun nötron radyasyonuna karşı koruyuculuk özelliklerini karşılaştırmak olduğu anlamına gelir. Her iki örnekte de örneklerin kalınlığı 2 cm ile başlamış ve 2 cm'lik artışlarla 10 cm'ye ulaşmıştır. Kalınlığın etkisi ve malzeme tipinin nötron zırhlama davranışı üzerine etkisi araştırılmıştır. Deney sonuçlarına göre, saf beton numunelerinin daha üstün özellik gösterdiği görülmüştür.
