Japan Radiation Maximum by Prefecture
The UN nuclear watchdog, the IAEA, warned today that the situation remains 'very serious' at the Fukushima nuclear power plant. Many Japanese citizens are therefore obviously worried about radiation levels.
This TargetMap creation uses Google Maps to show the real-time radiation levels by prefecture. The data comes from the the System for Prediction of Environment Emergency Dose Information(SPEEDI). The results shown are the maximum values recorded in the latest update.
RDTN.org Japanese Radiation Levels
RTDN have created a Google Map of radiation level readings in Japan with data from Pachube and Marian Steinbach.
Each marker on the map displays the radiation level and the time of the reading. RTDN are also looking for people to submit their own accurate readings to the map, which you can do via a short form.
To provide context for these map you should also check out O'Reilly Radar's Open Street Map visualisations of radiation levels in Japan. The O'Reilly maps compare two days of recent radiation data with the normal radiation levels in Japan.
