18x Background Radiation, ST Louis MO 5/13/11 Evening

This sample was from less than 50 drops of rain water on my SUV, taken on the evening of 5/13/11. The sample stabilized at 0.186 mR/hr. The reading is high given the small amount of water, and data from EPA's RadNet that a significant amount of Gamma and Beta radioactive fallout had washed out of Saint Louis air approximately 20 hours earlier in a overnight rain storm. for details see:  [ALERT] Avoid Produce and Dairy: EPA shows Radioactive Fallout Dumped in STL
