Via Japan Today: Elevated levels of radiation measured inside reactor buildings. Excerpt:
Elevated levels of radiation have been measured inside the buildings housing the Nos. 1 and 3 reactors at the troubled Fukushima Daiichi nuclear power plant, the nuclear safety agency said Monday.
The Nuclear and Industrial Safety Agency suggested that the readings—measured at between 10 and 49 millisieverts per hour for the No. 1 unit and between 28 and 57 millisieverts per hour for the No. 3 unit—put time constraints on any work that must be done inside the reactors.
