On Thursday, March 17, 2011 13:57 JST (12:57 a, Thursday March 17 ET) NHK reports that "radiation levels at municipalities in Fukushima Prefecture continue to be higher than normal. But authorities say the detected levels pose no harm to human health. Health authorities say one-hour of exposure to radiation at any of the observed levels would range between one 500th to one 40th of the amount of radiation the body would receive in a single stomach X-ray."
As of 9 AM Thursday (08:00:00 p.m. Wednesday March 16 ET)

thanks for all the information!
Just wondering at what level of radiation, is a situation considered Hazardous to human health, or even a full on 'evacuate everyone' emergency?
