It gets worse... "The cumulative releases from Fukushima of iodine-131 and cesium-137 have reached 73% and 60% respectively of the amounts released  from the 1986 Chernobyl accident.  These numbers were reached  independently from a monitoring station in Sacramento, CA, and Takasaki,  Japan.  The iodine and cesium releases are due to the cooking off of  the more volatile elements in damaged fuel rods." - SlashDot 
One of the best of the new radiation maps was developed by Portland’s Uncorked Studios. In only 72 hours they created RDTN.org,  an online display of up to date radiation levels across Japan and  neighboring regions. Their information is gathered from volunteer and  official sources and embedded onto an adapted Google Map. Three days  from concept to a working map that gives valuable and reliable data to  anyone who wants it for free, and not a dollar was spent in its  production. Amazing.
 Another great map of radiation levels was created by South Korean firm ISELSoft using their STUBBY web bots. The Stubby map compiles  data from the web, gathering readings from various monitors across  Japan, Korea, and Central Asia. It also color codes the data to reflect  hazard levels. While it doesn’t have as many data points as RDTN, it is  clear, easy to read, and regularly updated. Another winner.
 While many of those wanting to track radiation levels after the  Fukushima accident do so out of sympathy for Japanese citizens, let’s  not ignore the fact that many others are simply worried about when  dangerous radiation levels could show up in their own backyard. Along  with maps detailing Japan, there are also a few looking elsewhere on the  globe. The best example was created by Mineralab, producers of Geiger  counters and related supplies. Their Radiation Network  map shows radiation levels reported from individual monitors across the  US. It also marks the location of nuclear facilities. The map is  updated every minute, giving you radiation readings almost in realtime.
 There are several reasons why RDTN and the Stubby map are superior in  my mind to the Radiation Network: They include a large amount of data  from a number of reputable sources, they focus on the area most  concerned with the accident, and the quality of their images seems  better. Radiation Network, however, may give us a better idea of what we  can expect in the future. While the first two maps are specifically  geared towards the Fukushima Nuclear Power Plant crisis, the latter is  taking a much broader scope.
