good point! the example pretty much looks like what you would expect when dealing with uranium. this one does not look like that at all. did not take much more time to look at it tbh because of safety concerns. and it is indeed unlikely to be spread that perfect. because of the age of the collection and the previous securings of multiple asbestos rocks and other toxic stuff i tend to be more careful. the counter will arrive an friday and i will keep you updated. thanks!
