Remember the Packbots from iRobots that went inside the Reactor buildings (1, 2, and 3)? The Packbots didn't go in from the south door of the Reactor 1 building because the radiation at the south door had measured 270 milli-sievert/hr the previous day. So the bots cannot enter if the radiation is that high, but the workers are obliged to dodge the debris with even higher radiation and continue to work. One unlucky worker got to remove the 900 milli-sievert/hr concrete piece.
Unconvincingly, however, the Kyodo article claims the high radiation level on the compound will not derail the schedule of the roadmap that TEPCO has announced.
I've read on several Internet message boards in Japan about how the workers have been doing their best to avoid the debris and water puddles on the compound because of the very high radiation, and how the dosimeter starts beeping right away just by standing in front of the Reactor buildings. I guess they weren't the "baseless rumors" after all, and it seems the workers are more expendable than the bots.

Fukushima radiation map exists
EX-SKF posted a good read yesterday. Apparently, TEPCO has a map of the radiation surrounding the Fukushima Daiichi nuclear reactors, and TEPCO is more concerned with protecting its iRobot Packbots than their human contract workers.
