Determination and calculation of gamma and neutron shielding characteristics of concretes containing different hematite proportions

To obtain gamma and neutron attenuation characteristics experimental measurements and Monte Carlo simulations were carried out for hematite-loaded concrete samples. Also, the mechanical strength of samples was studied. However, the results for neutron attenuation reveal that there is no effect of hematite inclusion in concrete with respect to the neutron absorption capability. Gamma-ray attenuation capability and the mechanical strength both increased with increasing the hematite percent. (C) 2011 Elsevier Ltd. All rights reserved.
