According to that chart 100 millisieverts/year (or 0.01 per hour) is linked to increased cancer risk. The readings in cities near the reactor look like between 0.1 and 0.8. Not good if it doesn't go down.

#9This is a great idea but it would be much more useful if the pins were color-coded to indicate danger levels.

#10It lists figures like "800Gy/h" which is far higher than the radiation level at Chernobyl, right after the accident, standing right beside the blown reactor.
If you check the sources, the units are in nano Gy/h. Their conversion to milliSievert is closer but still off by a factor of a 1000.
So the highest reading I can find is 700nGy/h at Hitatinaka: http://www.houshasen-pref-ibaraki.jp/present/result01.html
If you turn that into a yearly dose, using a weighting factor of 1 as the monitoring station website suggests, that's 6milliSievert/yr: the average yearly dose from background radiation. Exciting!
There's really no justification to make such a website.
