Abstract:
Nowadays, there are various types of x-ray applications in human daily life. The uses of radiation required proper shielding equipment to prevent overexposure of radiation. Shielding material made from BiPO₄-AC from used paper were investigated in this study. Three different ratio of BiPO₄/amorphous cellulose were prepared and tested using different ratio of silicone rubber (SR) as fabric coating. Radiation attenuation ratio (%RAR) were measured at 30, 40 and 60kV. The result showed that 1:1 BiPO₄-AC with 1:4 filler-SR performed the best shielding performance at 35.23% at 30kV with the presence of 0.569 g of BiPO₄. The increased of BiPO₄ content also resulted in the increase of shielding efficiency of the sample. Furthermore, BiPO₄/AC substance with higher ratio shown better binding texture. Hence, the addition of amorphous cellulose could enhance the strength of the BiPO₄/AC composited compound which give them ability to be further developed into different form of non-toxic x-ray protection equipment.
