A remote controlled robot that uses dry ice to vacuum up radiation was unveiled by Japanese researchers on Friday, the latest innovation to help the clean-up at Fukushima.
The caterpillar-tracked device blasts dry ice—frozen CO2—against floors and walls, evaporating and carrying radioactive substances with it, engineers said. The nozzle also sucks up the resulting gases.
The robot has two boxy machines the size of large refrigerators and moves on crawlers that are remotely controlled. Each machine has four cameras that allow the device to “see” what it is doing, an engineer told reporters....

This is a great start and something positive to talk about in regards to radiation.
Very good for decontamination of materials and equipment but a hovercraft type vehicle is almost needed to go over terrain and capture these radio-active particles.

who is going to clean the machine.. and add dry ice every half hour.. why dont they let prisoners volunteer to do some clean up.. where does radiation go.. it does not just evaporate... it must blow downwind.. I know of a ranch where people from Sendai can come in Hawaii if they have skills and want to get out of this crazy place for a while..

Kimokekahuna Hawaii - Just to break it down for you : Prisoners are HUMAN BEINGS and are affected by radiation, just like you would be. .......................... A Robot (on the other hand) is a machine so it can take all kinds of exposure. .....Certainly the clean up ,restocking of dry ice, and any "waste" dsiposal would be done in quarantined places with workers fully covered............................

I imagine this thing moves pretty slow given the size of it. They need to connect some kind of tube to it so it can keep working, otherwise the dry ice will evaporate before it gets anywhere useful.

so really... where do the store the dry ice once it is vacuumed?
