Due to work, waaaaay behind on everything. Diving into comments now, oldest first.
Saw the smoke links, this one from Sparkey. Old hat by now? The earlier post on airborne is probably well-past “worst-case” for the event. If not, I’ll break out the ALL CAPS.

(Click to enlarge.) Have yet to read it, but expect to study it.
“Skymaster” Ronny finds a “Dr. Weather Blogger” who is now done with the plume unless there’s another major explosion.
crosspatch continues with a close eye on the site’s radiation levels, says they’re still dropping (this was 11:18 eastern time). Also provided the link to the fission curve mentioned earlier.
Will you click that above link if told it was originally dubbed the “Jane Mansfield” curve, and later the “Dolly Parton” curve?
oldHP provided radiation info from the NEI, cleverly finding a report that spurned the Sv in favor of a man’s unit.
Rates at the plant site boundary range from 1 to 3 millirem per hour. Radiation dose rates in the area where fire trucks have been located are reported to be 2 to 3 rem per hour, with some isolated areas as high as 30 rem per hour.
…wait. “A man’s unit”…unintended, I swear!
Okay, let’s just go ahead and post the image everyone keeps sending:
It is great.
Finally, crosspatch has some “good news/bad news”:
4am (Tokyo) news from NHK
1km west (of “the facility”) 540 pm 494uSv
rose 1932uSv 1 hr later
dropped to 380uSv at 3am
Rise likely due to wind causing the “smoke” to blow toward the monitoring post.
Good news–those numbers seem lower. Oh wait! It’s one km away, not that 500 meter distance I was getting used to. Anyway, if the wind really is whipping ~ 1.5 mSv/hr. (150 mrem/hr.) materials back and forth through the air…urk.
