Radiation too high after nuclear melt-through to allow clean-up crews into the facility? Just air out the facility and spread all the radiation fun around. Problem solved.
From NHK World:
Tokyo Electric Power Company plans to open the doors to the reactor Number 2 building at the Fukushima Daiichi plant for ventilation, to lower humidity and start restoration work.
Tokyo Electric said on Thursday that an air purification device, which has been working since last Saturday, has reduced radioactive concentration inside the building to levels that have little impact on the nearby environment.
The utility said the concentration of radioactive iodine in the air has been reduced to about one-10th of former levels and radioactive cesium to about a quarter, as of Wednesday night.
