Radiation is escaping from the Fukushima nuclear power plant after multiple explosions at the site.

BBC: Massive explosion at Japan nuclear power plant. With video, terrifying, of the Fukushima I plant blowing up. BBC News live report: 0227: There were two explosions at Reactor 3, the operator Tepco says – AFP.
ABC, Australia: Explosion at quake-hit nuclear plant.
We are implementing a measure to reduce the pressure of the reactor containment vessels, but, one of our employees working in the Unit 1 was irradiated at over 100mSv level(106.3mSv). Because of absence of industrial physician, so he will be diagnosed at a later day.
We measured radioactive materials inside of the nuclear power station area (outdoor) by monitoring car and confirmed that radioactive materials level is higher than ordinary level. Also, the level at monitoring post is higher than ordinary level.
Still is from live coverage from NHK of #3 reactor explosion.

A city map, in English, from Fukushima City; use the mirror copy since the municipal site is overloaded.
Original source: http://www.tepco.co.jp/fukushima2-np/monitoring/images/mp1.gif I am unable to determine precisely what the graph measures, but the metric is in "nanogreys per hour", a measure of radiation dose. The spike is associated with the first of the two explosions.
Evacuation zones, based on post collected by EMN, showing a 10km zone around both plants. I'm not quite sure who TMN is, and I don't read the Japanese. The zones have since been expanded.

A second wind map from the same source, collected just after the explosion at unit 3.
