Gamma ray interactions with flyash concretes for different geometries : 9783659762451 : 23 Jul 2015 : Different materials differ in their radiation shielding ability along with the cost, efficiency, space and ecology considerations. The only practical shielding material satisfying these requirements is concrete. The most costly and energy intensive component of concrete is cement and needs to be replaced by a pozzolanic material. So the radiation shielding properties of different series of concretes having varying flyash content (with different chemical admixtures) have been studied for different geometries with different energy photons. The safe disposal problem of flyash, encountered by thermal power stations can also be solved to quite an extent. So its usage in concrete can lead to dual advantage. The present book is an attempt for elaborating the radiation interaction parameters describing attenuation and multiple scattering of photons for narrow and broad beam geometry setup as t
