Potentially Crazy High Radioactive Rainfall in Indianapolis

The samples were taken in Indianapolis Indiana on 7/3 and 7/4 of 2011 as part of our 4000 mile radioactive road trip
.
The 7/3 sample was bone dry dust wiped from the hood of my car; it had rained heavily approximately 6 hours earlier. The 7/4 sample was from fresh rainfall and returned a radioactivity of approximately 10 times greater than background radiation.

I decided against publishing a back-calculated radioactivity for the 3am 7/3/11 rainfall because of the known unknowns regarding the sample and the high radioactivity the calculation returned.
