I am joining mostly to publish my findings on the big map.
Here are the specs:
-Location: Redmond, WA (approx. 47.670436843289885,-122.1065757935866)
-Geiger counter: GQ GMC-320+V4
-Tube: Whatever is default with this unit
This is mostly an indoor counter. On the west coast there are many of us who have been watching radiological impacts due to the Pacific currents and Fukushima fallout. And, of course, because it is fun.
