Edano said "1,000 milli-Sieverts" had been measured last night, but that it was down to under 800 now, and that at the gate the measurements were now in the milli- range as well (hence the evacuation).
Those are Edano's words, not the BBC's. I was told above that he was corrected by another person and that various translations have it as a different figure, but that isn't in the linked video.
