Radioactive decontamination

Use Oxidizer, disinfectant, deodorizer, bleach, dye, tanning, radioactive decontamination of skin, reagent in analytical chemistry, medicine (antiseptic), manufacture of organic chemicals, air and water purification. 

Titanium dioxide, TiOj, is a white powder and has the greatest hiding power of all white pigments. It is noncombustible however, it is a powder and, when suspended in air, may cause a dust explosion if an ignition source is present. It is not hsted in the DOT Hazardous Materials Table, and the DOT does not consider it hazardous in transportation. The primary uses are as a white pigment in paints, paper, rubber, and plastics, in cosmetics, welding rods, and in radioactive decontamination of the skin.

Kaneka Corp., a Japanese chemical company has established an efficient radioactive decontamination strategy by using their biosurfactant, called Kaneka Surfactin, which is composed of surfactin. They successfully carried out decontamination of areas affected by the Fukushima No. 1 nuclear power plant disaster. Efficient surface and detergent activity of surfactin make it eliminates radioactive cesium and other contaminants from the polluted area. Strategy adopted by Kaneka Corp. for radioactive decontamination of roads using surfactin solution is shown in Figure 14.8.
