Corporate Incompetence: TEPCo says Cesium building up inside reactor buildings, could be from mini explosions!

Tokyo Electric Power Company reporting that cesium levels inside Reactor 2 building are shooting up.  The latest measurements showed 65 times current government emergency limits for reactor buildings.

TEPCo has been monitoring airborne radiation levels inside Fukushima Daiichi’s reactor buildings, using robots, because radiation levels became too high for humans.

TEPCo says the build up of cesium-134 could be from steam and explosions from within the reactor.  But they admit they’re not sure why the levels are increasing, and will continue their investigations.

Why didn’t they do what Bill Nye the Science Guy said, and pave the thing over?
