The IAEA have just measured very high beta/gamma contamination 4,900,000 beq / metre squared in Fuk. Pref.

"At distances between 30 and 32 kilometers from the Fukushima Nuclear Power Plant, in a north westerly direction from the site, dose rates between 16 and 59 microsievert per hour were measured. At these locations, the results of beta-gamma contamination measurements ranged from 3.8 to 4.9 Megabecquerel per square metre. At a location of 21 km from the Fukushima site, where a dose rate of 115 microsieverts per hour was measured, the beta-gamma contamination level could not be determined."

Here is a map of Chernobyl's "Zone of Alienation"

I converted 40 curies / square km to 1.48 Megabeq / square metre



Also 1.48 is mentioned here:

We seem to have 4.9 Megabecquerels in Japan

edit: Forgot to mention not all of the radiation detected yesterday by the IAEA was from Cs137, there will be Iodine,Strontium,Cobalt etc and maybe Plutonium too. Also one site was "unmeasureable", but mSv was highest at that point !
