The robots being used inside the plant are made by Bedford, Massachusetts, company iRobot. Traveling on miniature tank-like treads, the devices opened closed doors and explored the insides of the reactor buildings, coming back with radioactivity readings of up to 49 millisieverts per hour inside Unit 1 and up to 57 millisieverts per hour inside Unit 3.
Ovo već znamo, ali poređenja radi:

The legal limit for nuclear workers was more than doubled since the crisis began to 250 millisieverts [per year]. The U.S. Environmental Protection Agency recommends an evacuation after an incident releases 10 millisieverts of radiation, and workers in the U.S. nuclear industry are allowed an upper limit of 50 millisieverts per year. Doctors say radiation sickness sets in at 1,000 millisieverts and includes nausea and vomiting.
U kontradikciji s optimizmom da će do kraja godine kriza biti rešena:

The head of the Atomic Energy Society of Japan, Takashi Sawada, said yesterday that fuel rods in reactors 1 and 3 have melted and settled at the bottom of their containment vessels, confirming fears that the plant suffered a partial meltdown after last month’s huge earthquake and tsunami.
“That would destabilise pressure and temperatures inside the reactors and the situation would become extremely unpredictable again,” he said.

Meanwhile, Japan’s Nuclear Safety Commission revealed this week that it had waited weeks to publish information on elevated radiation levels from the plant last month partly to avoid panic. “Some foreigners fled the country even when there appeared to be little risk,” said Seiji Shiroya, an official with the independent government panel. “If we immediately decided to label the situation as Level 7, we could have triggered a panicked reaction.”
