The video of his July 25 tour of the crippled plant has been uploaded by the IAEA.
As they approach Reactor 3, the survey meter keeps beeping, alerting them to a high radiation level even at that distance (about 1:32 into the video).
Devastation from tsunami looks just as bad as in the earlier videos (about 2 minutes into the video).
Toward the end of the video, the survey meter shows "88.3". I suppose it is in microsievert per hour.
