Anders Sandberg looked at this question a few years ago.

His rather basic analysis of the problem indicates that there is a risk, but it is fare from uniform all over the galaxy, and isn't even 100% in the galactic centre.

Mapping this onto the densities of stars in the galaxy shows that there is a cluster of (probably) unaffected stars in the Galactic Habitable Zone near the plane, which is where we are.

This does mean that any civilisation near the Galactic Hub probably migrated there, or it must somehow have evolved to be highly resistant to radiation events.
