Fukushima: Japanese Radiation Monitoring Data Google Maps Mashup, Fukushima source term

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.


Eron Villarreal has put this data in a data dashboard using Tableau Software.



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).

  1. I really appreciate the posts you've been making. This is opening up a world related to radiation monitoring data that I was just previously scratching the surface of.

    As a side note, the recent spike in Ibaraki Prefecture seems a little concerning, but it's likely due to nothing other than a change in wind patterns.

  2. Alan,

    Thanks.

    You know the more I think about it, the more I think there ought to be a larger network of open radiation monitoring data over several countries.

  3. I might be jumping the gun a little bit here, but I'm kind of thinking right now that after this incident - there will be one.
