Technology:
Toshiba developed a
new remote decontamination robot in alliance with the Ministry of Economy, Trade
and Industry. The new robot sprays fine particles made of dry ice at high
pressure to clean floors and walls contaminated by radioactive materials. Test
operation will start this month in Fukushima.
After checking the performance, it will start operations this summer. Toshiba
compared and discussed more than 1,500 decontamination technologies that the
ministry collected from the general public last year and established the method
effective for the place that dried after being exposed to contaminated water.
The new robot
decontaminates the floor using the impact created by spraying dry ice and the
expansion force created by dry ice when it sublimates into carbon dioxide gas. The
movable arm moves while spraying dry ice and decontaminates up to two-square-meter
per hour. The new robot collects contaminated materials created by cleaning simultaneously
as a vacuum cleaner does.
