This doesn't work, since the nanomachines are just as vulnerable to
radiation as biology. Building hardened systems might work, just as the
radiodurans bacterium manages to survive intense radiation by using a
large percentage of its energy for error repair. But it would require
plenty of time of preparation before the radiation storm to build an
ecosystem-wide nano-repair system.
