The government agency responsible for safety is saying "it's difficult to tell if there is any significant damage to the power plant"
This kind of statement is a complete lie. They are judging based on the radiation detected in the air. The operators have started venting to release some of the heat to cool down the core. Detecting radiation, I'm sure, is a fool-proof science that couldn't possibly be inaccurate (/sarcasm)
These guys are covering up ahead of a meltdown. I hope it doesn't come to that, but the Fukushima nuclear plant is FUBAR at the moment.
