[Good News] 2x Background Radiation Rain in STL @ 9:20pm 5/15/11

Its been more Seattle type weather here in Saint Louis, Mo; mostly nasty cold drizzle.
I just took a sample from the hood of my truck, it has been sitting in the drizzle for last 12 hours and was driven roughly 7 miles earlier in the day. The sample returned a max of 0.020 mR/Hr. The EPA RadNet charts indicate another washout of Beta emitters, but the Gamma emitters are still in the air. It is possible that the low cloud cover and drizzle may not have the same efficacy at washing out radioactive fallout as the strong storms have done here in the past. More data collection will be required to support any further analysis.
