After the Great East Japan Earthquake, Iwamiya was concerned about the development of radiological shielding wear using her silk glass technology to coat glass on Japanese paper for making a polygonum filiforme “mizuhiki”. This technology is characterized by a chemical reaction technique based on the sol-gel method for glass, and by excellent bonding-ability of glass to both organic and non-base inorganic materials selected as a combination according to their application. In this time, a combination of tungsten powder and fabric was selected. A stable radiation-shielding cloth was produced through processes of mixing the powder into transcendental glass liquid, coating them on the fabric and heat treatment. By further crimping a soft shielding cloth, it became excellent in flexibility and better shielding properties. The radiation shielding property was equivalent to lead. A desired a half-weighted and more movable radiation shielding wear compared with the conventional one was successfuly made by using the three-fold crimped cloths.
