High radiation level detected 30km from nuke plant

[FBaggins]

Japan's science ministry says radiation levels of up to 0.17 millisieverts per hour have been detected about 30 kilometers northwest of the quake-damaged Fukushima Daiichi nuclear power plant. Experts say exposure to those levels for 6 hours would result in absorption of the maximum level considered safe for 1 year.

The ministry gauged radiation from 9:20 AM to 3:00 PM on Thursday at 28 spots, in areas 20 to 60 kilometers from the plant. The ministry also observed radiation levels of 0.0183 to 0.0011 millisieverts per hour at most of the observation points.

It says these levels are higher than normal but pose no immediate threat to health.
