      Not really, once dna has become significantly damaged it is very difficult to repair it.

      At the moment there is not, as you radiate the cells you mutate the DNA and it cannot replicate as the DNA contains the instructions on how to make a cell as soon as the radiation damages this, the cell can no longer replicate and ceases to be.

      Not with the medical technology we have available- DNA contains the information to repair itself and any affected cells, but DNA damaged by radiation often cannot repair itself, and its information can be lost.
