Radiation Map : work in progress

 A recent news article got me thinking about Geiger readings in Japan, after a bit of Googling I came across some cool things like an upcoming Geiger shield from the Tokyo Hackerspace, and an aggregate data feed from Pachube with nearly 500 live datapoints. Excited to have all this data I decided to whip up something simple (in Processing) to plot it all on a map. I’ve been looking into to applying a predictive modeling construct (perhaps something like an ensemble Kalman filter with an atmospheric dispersion model for Cesium 137), to be able to plot the theoretical radiation levels in all of Japan. I tried modeling it simply with exponential decay, but the results were pretty abysmal.. hopefully I’ll hear back from my environmental studies contact and have something legitimately cool to show you shortly.
