Review on scope of metallic alloys in gamma rays shield designing

With an aim of efficiently using radiations in different fields, radiation physicists are continuously exploring different type of materials in terms of visualizing various parameters. Besides physical parameters viz. density, hardness/structural strength; special emphasis has been given to radiation shielding parameters which includes mass attenuation coefficient (mu(m)), effective atomic number (Z(eff)), electron density (N-e), mean free path (mfp), half value layer (HVL), tenth value layer (TVL), exposure buildup factor (EBF) and energy exposure buildup factor (EABF). In the present work, an attempt has been made not only to summarize the various investigations made so far on visualizing the feasibility of alloys as radiation shielding material; but also to provide comparative study for further consideration to be used in other fields.
