Does anyone have a Geiger device for reading the CPM on theese marbles as well as for Tritium? I know they are safe and all but for my peace of mind I know that normal gamma radiation is about 20-30 CPM all around us, and some uranium glass has about 300 or so, but isn't dangerous till about 1000. If anyone could test this I would pretty much appreciate it.
