All sources of available cooling seem to be at work. The Tokyo fire department is hosing water into Units 3 and 4 every time the water level drops low enough through dissipation, the power cable has been completed to run the emergency cooling system in Units 1 and 2. And some functional diesel generators are working on cooling Units 5 and 6, whose temperatures have steadily risen up to ~65 Celsius as of 4PM JST.
Radiation readings outside of the 20km perimeter show 8 areas with abnormally higher radiation than the rest: 158, 61.6, 95.1, 170, 59.3, 91.8, 58.6, and 167 microsieverts per hour. The remaining locations read around 10 microsieverts per hour, with the most part being under 5.
All of the high readings are picked up around 30km away from the plant in the NW or WNW directions and are thought to be the result of a controlled containment venting and a simultaneous fire.
High as it may seem, the level still peaks at 170 microsieverts per hour, which is equivalent to taking 2 X-ray pics per hour, I wish I knew how long it'd take for these to decay, though.
