Per the Geiger counter's owner (CerebralProgrammer) 20 CPM (counts per minute) is the normal background radiation level. I first noticed an unusually high reading last night at about midnight CST. Tonight I have recorded a 2 minute or so sampling of high readings where 100 CPM is touched or exceeded, or 5x background.
