Getting more severe

Tepco has not yet solved its water problem.  Japan's nuclear agency has upgraded the severity level of a radioactive water leak at the Fukushima plant from one to three on an international scale where seven is the worst.  The water is so radioactive that teams must be constantly rotated and it is clear that most of the toxic water has already disappeared into the ground.  The radiation level is strong enough to give someone a five-year dose of radiation within one hour, so the repair crew has to be constantly rotated.
