I think the 13 workers who took undue risks (exposure to up to 32 Gy) were old workers from the company who volunteered to go in danger area to secure them, but i don't know if they were local (doesn't matter anyway, they are heroes). And the fact that none of them developed a cataract or blindness, no hypertyroid, and only one got a cancer (for now, radiation cancer can happen after a lot of time) is a small miracle. Workers who were around the danger area but did not enter them were probably banished from flying a plane or working in nuclear for a year or two, but should be fine.
