12x Background Radiation In 7/8/12 STL Storms

We captured our first live airborne radiation reading during a thunderstorm from our new outdoor radiation monitor. Live data from our Saint Louis outdoor Geiger counter may be seen at the following link.

The live data indicated an approximate 4 CPM jump from 14 CPM to 18 CPM. A sample swipe taken from our truck after the rain ended indicated levels about 12 times greater than background.
