Speech Title: Development Of Advanced Non-Toxic, X-ray Radiation Shielding Material Useful For Broad Application Spectrum
Aims: For the first time a novel process for making advanced non-toxic radiation shielding materials useful for broad application spectrum like X-rays, CT scanner rooms and other nuclear installations in various polymeric matrixes has been developed at CSIR-AMPRI, Bhopal. The developed novel technology involves the use of industry wastes like Red Mud, Fly Ash etc. which inherently possesses multi-elemental, multi-component phases in them.
Methods: The developed technology basically involves chemical and ceramic treatment of Red Mud -An Aluminium industry waste.The synthesized fabricated material in the form of tile, panel etc. have high density with multilayered, multi-crystal and multi shielding phases necessary for achieving radiation shielding properties.
Results: The developed material has been evaluated for their diagnostic X-ray attenuation characteristics. The attenuation for different energies of X-ray photons have been computed and found to give very effective shielding properties. Also, the developed shielding material is characterized by using various sophisticated and complementary techniques like FTIR, TGA, DSC, FESEM, EDXA, XRD and AFM etc.
Conclusions: A novel process for making advanced non-toxic radiation shielding material useful for broad application spectrum has been developed by utilizing various wastes as resource materials like Red Mud, Fly Ash etc. in various polymeric at CSIR- AMPRI, Bhopal and have following significant features:- like Non Toxic – Lead free & rare earth free, capable of shielding X-Ray and is cost effective.
