According to Asahi Shimbun which is quoting the Japan NRC, the Fukushima event has just surpassed Three Mile Island in terms of seriousness, and has been upgraded from Level 5 "Accident with Wider Consequences" to Level 6 "Serious Accident." Only Chernobyl is a Level 7 event. We believe Fukushima should get there within 2 weeks as ever more of the current devastation becomes public. Of course, all of this is a paper-pushing formality since it is quite clear now that a cover up of the real devastation is in place.
They simply had to raise the level to avoid losing credibility after two workers at Fukushima plant were diagnosed as having sustained beta ray burn injuries.
TEPCO said radioactive water may have seeped through their radiation protective gear. The injuries are caused by direct exposure to beta rays, the utility added.
