Now I read it through again, I'm sure you're right Adam. I stand corrected.
The subduction idea is not bad, only it's very hard to find a place 
where you could actually get the stuff moving into the zone, there's 
more chance of it being pulverised and distributed into convection 
currents back to the surface - there have been ideas of droppng it into 
the Marianas Trench too, but who knows what those kinds of pressures 
would do. However, the greatest problem and safety risk is still 
transporting it to wherever it's to be dumped.Although Chernobyl was so 
long ago, and relatively far away, there are still official warnings 
here about picking and eating wild mushrooms, apparently they still 
contain too much Strontium 90.
