Marian Steinbach decided to scrape the radiation monitoring data from the Japanese Radiation Monitoring Network (SPEED) we featured earlier here, so that people would be able to use these data for potential mash-ups. ( see An Update on Radiation Data from Japan ). Then, Geir Engdahl put this data in a google maps. The data is refreshed every ten minutes.
In particular south of Fukushima, near the town of Hitachinaka, we can see:
Here the dose is in nanoGray/hr. 3000 nGy/hr is equivalent to 3 microSv/hr given a weighting factor of 1.
It would be great if any simulations performed by any of the outfits we have mentioned earlier were to provide their data in a format that can fit a Google Maps mashup format (if you are one of these researchers but don't know how to go about this please contact us).
