23:35 Development of Tungsten Based Paper Capable of Blocking Radiation
Toppan Printing and Kyoto University have jointly developed a special tungsten-based functional paper capable of blocking radiation. The newly developed paper takes advantage of radiation blocking property of tungsten, blocking such radiation as X-rays as well as gamma rays. The new functional paper is very easy to manufacture, where it can be cut, folded, or even can be affixed to other materials such as films. Being lead-free, the new product can be used for both indoor and outdoor applications where it comes into contact with people. One such application is in area of medicine where the walls, doors and curtains of radiology rooms and radiation therapy rooms can be covered with the materials, or it can be used as simple shielding materials in operating theaters as well as medical wards where it is difficult to block radiations. It can also be used as shielding materials for floors that have been contaminated in nuclear medicine laboratories and for transport boxes for radioisotopes. Other practical applications involve in regions affected by the nuclear disaster and recovery work by protecting individuals working in radioactive conditions and simple radiation shielding of contaminated materials and waste. It can also be used as building materials for building new evacuation centers such as gymnasiums in the affected areas. Toppan Printing will make sample shipment of this new paper for the medical as well as décor materials industries.
