>>The main contaminants are Cesium 137 and Cesium 134, they are split about equally. The radioactive halflife of Cs 137 is 30 years the radioactive half-life of Cs 134 is 2 years. When the robots find a radiation source they dig it up. In that process they have the ability to interact with the waste and to sort it. High level waste is vitrified in situ by a CNC plasmic vitrification machine, which this is an example of. Waste is vitrified into a stable glass like material. >>Mid and low level waste are left in the landscape as artifacts of the contamination. Their shape is directly dictated by both the substrate that they are adhered to and the levels of radiation that they have. The shape is dictated again by an equation of shielding-for a certain thickness of material there is an amount of radiation reduction that takes place across it. So for any shape thereâ&#x20AC;&#x2122;s a mediating attribute to it. The creation of those shapes is driven by the specificity possible though CNC controlled plasmic vitrification. >>High level wastes are taken out of the landscape and transported back to the actual Fukushima Daiichi site for permanent sequestration. At the entry of the project they are scanned and quantified to be catalogued into a robot readable waste archive. High level wastes are then reprocessed and concentrated into archival blocks while low levels wastes are separated out and used to fabricate adaptive shielding. Similar to <this> material. The thickness of any given tile in the network is dictated by the amount of shielding necessary at that point. So the thickness reduces the initial dose on the ground to a background dose on the new surface, effectively nullifying it.
