At 12:15pm, we took a paper towel swipe from a piece of sheetmetal that had been left out in this morning's rain. That sample returned 22X greater than background radiation. The reading is about twice as high as we would expect from the post Fukushima southern Jetstream.
Our full time airborne radiation monitor's average moved up by one standard deviation during the 3 hour rain to about 18cpm. The Jetstream was broken but position above Saint Louis during this reading period.
