Tungsten-Coated Cloth for Radiation Shielding Made with the SilicaTech® Coating Technique

Abstract

The radiation shielding cloth was developed by coating tungsten powder on polyethylene cloth with the SilicaTech®︎ coating technique in order to guard Fukushima children from radiation after the TEPCO (Tokyo Electric Power Holding Corp.) Fukushima Daiichi NPP (Nuclear Power Plant) Accident. The glass film was reliably adhered to both the cellulose of cloth and tungsten powders by the siloxane bond. Shielding ability was found to be more than two times compared with same weight lead in the experiments. The cloth is so softer than the other materials for shielding cloth that even woman can easily wear and move.
