Abstract
A novel eco-friendly method has been developed for the fabrication of high dense (3.3-5.2 g/cc) red mud based material blocks for shielding high energy X- and γ-rays. The red mud based material blocks with various densities were fabricated by hot compacting partially melted red mud, red mud:Bi2O3, red mud:Ba(OH)2 and red mud:Bi2O3:Ba(OH)2 samples at 1150° C., 1000° C., 1050° C. and 1000° C., respectively. This material can be used to build radiation shielding structures in medical diagnosis, radiotherapy, industrial radiography, particle accelerators, food sterilization plants, nuclear power plants, and radioactive material storage rooms, without further structural support unlike lead (concrete walls). It is economically viable and will suppress the accumulation of hazardous red mud and associated environmental pollutions.
