In order to protect from the unrecognized exposures to high‐energy γ‐rays, Yongsok Seo, and co‐workers, article number 1901448, prepared nonleaded metal (BiSn)/polymer and tungsten (W) composites. A multi‐layer (BiSn / polymer)/W laminate can offer a sufficient thickness with flexibility and an effective shielding against γ‐rays to be used for protective clothing or equipment.
To effectively attenuate unrecognized and/or unwanted exposures to high‐energy γ‐rays which leads to occupational hazards when accumulated in a wide range of industries, nonleaded metal (bismuth(Bi)‐tin(Sn))/polymer and tungsten (W) composites are prepared and tested. A eutectic alloy, BiSn, with a low melting temperature of 139 °C, is applied for the first time to prepare a γ‐ray shielding material...
