I was also having this thought. I did a little searching and came across this

http://mashable.com/2011/08/18/google-maps-weather/ what about adding a button that can toggle on and off the weather layer? (wind directions and rain)
I also came across a googlemaps nuclear powerplant layer with pinned info about the year it was build, the amount of generated power etc. Can’t find it right now but i will add a link as soon as i find it again.
EDIT: http://www.theguardian.com/environment/interactive/2012/mar/08/nuclear-power-plants-world-map
And i’m sure there will also be a list of militairy sites where nukes are stored or suspected to be stored. And a list of sites where nuclear waste is being stored?
combining all of the above could then paint a nice picture if/how uRAD readings are related to weather and nearby (or not so nearby) powerplants.
Not sure if there is also data of radiation from outer space (sunspots), ozon layer, and the earths magnetic field. But I guess there are not enough monitors online yet to actually make sense of that data on the larger scale.
