A novel type of flexible composite with tungsten powder filled in polymers (TPFP) homogeneously was developed as an alternative to lead (Pb) based radiation shields used in nuclear industries. TPFP had a density in the range of 4 to 11.3 g/cm3, which can be tailor-made according to the applications. In addition to the advantage of lower toxicity over Pb-based shielding, TPFP can be formed into various shapes, such as pipe shields, pipe wraps, safe floor shields, blankets, etc. The mechanical properties and attenuation of γ-ray was investigated for the developed TPFP.
