The lack of an automatic repair mechanism makes things hairier, but while frozen, the radiation damage will be localized to the cells that get hit by radiation. By the time you get the tech to revive people from cryonic freezing, you’ll most likely have the tech to fix/remove/replace the individual damaged cells before reviving someone. I think you’re right that radiation won’t be a big limiting factor, though it may be an annoying obstacle.
