摘要: abstract Radiation shielding properties of concretes containing barite and colemanite in different rates were eval-uated by using 133 Ba (80.99 303 keV) 241 Am (59.54 radioactive sources. Gamma rays werecounted a NaI(Tl) detector with resolution 122 keV at 662 keV. The study reveals that the con-cretes under research are effective than ordinary concrete for attenuation gamma rays. It wasdetermined values mean free path decreased increasing concentration bariteand linear coefficients increased ofbarite concrete. Theoretical obtained Penelope WinXComcomputer programs these compared experimental results. 2012 Elsevier Ltd. All rights reserved. 1.
