BTW, this is also the basis of a story by Greg Egan. Diaspora. (Aside: I highly recommend Greg Egan's work, especially Diaspora)
The claim he makes in the fiction novel, is that a neutron star-neutron star collision event would be enough energy to sterilize 100 light year radius around the event. The one in the novel happens closer than 100ly.
