Hmmm. Could be pitchblende.
Lottsa uranium in that stuff.
Don't breathe the smoke or dust.
Handling is okay. Just wash your hands and face after. And any clothes contaminated by dust.
Unless you put a chunk in your pocket and carry it around. It's safe to handle.
Just don't store around people.
Actually shouldn't do that with any rock.
Here's a few samples.
Pick up one of these. Know for sure.
Quite an impressive device. For the money.
Phone connects to app showing spectral range and ID of all radiation thru net connection.
Love it !!
Worth every penny.
Wish I had this back when I did a little prospecting for it.
Only some kind of Geiger counter can tell for sure.
Some decent ones cheaper on Amazon.
Though will not specifically ID what radioactive ore you have. Like the Radiocode.
P. S.
Big chunky specimens bring a pretty good penny.
Mostly found in the SW. And an eastern region.
Radiacode is a portable radiation detector, dosimeter and spectrometer that uses a highly sensitive scintillation detector for analyzing environmental radiation levels in real time. 20 times faster than a conventional Geiger counter. Radiacode detects isotopes from the radiation spectrum...
