== Decontamination ==

Removal of highly dispersed radionucleotides deposited in complex and heterogenous solid materials is harder than removal of diluted atmospheric CO2.

Attempting clanup with mobile nanobot like devices highly dispersed into a natural environment might be '''fighting evil with an even bigger evil'''.
Relative to the contaminated mass only a small fraction of cleanup device mass is practical. Thus if at all possible cleanup devices must work fast and be pretty moile to cleanup faster than the natural decay would. Especially the mobility aspect of the [[reproduction hexagon]] is violated and there is the danger of being unable to recollect 
the purpously spilled nanomachinery. Theres the possibility of toxicity for all lung breathing life forms.

Withought weighing an atom it is impossible to determine whether it will decay or not. 
Radiation contamined soil and porous concrete and the like are complex materials.
They can't be simply systematically sieved through for radioactive atoms.
One could attempt to cut out micro sized pieces, evaporate them in hermetically sealed micro-chambers and try to catch only those elements that make the most trouble
like e.g. calcium test their mass and sieve them out if they're radionucleotides. (This is related to the recycling of [[slack]] problem. The more elements of the periodic table one is able to handle the better this works.)
Such a form of cleanup amounts to complete thermal destruction of any structure that was there and would require tremendous amounts of energy.

One can't really avoid destroying way more than necessary since radiation detection devices (e.g. geiger counters) can not be constructed in the nanometer size range.
So one can only get a very rough idea where the radionucleotides are located and needs to cut out huge blocks (cubic centimeter) that need to be thermalized.

Using chemicals to bind radionucleotides goes into the [[non mechanical technology path]].
