I just clicked the straw man here @nil by mouthj  - your contention is the FALSE one that radiation leakage is not commonly known?
If you'd read the article posted by myself and others in Popular Mechanics (I know you saw it because you referenced it, but clearly haven't read it) you'd see that it's commonly known and fully recognised that there was radiation released. Here it is again - please read it:

Also here's a follow up from ScienceMag on the analysis done on exposure of residents after the event.
