Matches background radiation.
My geiger counter could not detect any heightened radiation from these rocks.Any rocks you could find would be just a radioactive as these. I was worried I would be wasting my money.

1star reviewer doesn’t understand cheap Geiger counters can’t detect alpha particles-only beta/gamma
I didnt buy this product idk sellers, but I feel like the person who gave this seller a 1star review because their Geiger counter didn’t register much above ambient radiation doesn’t understand that most non-pro, cheap Geiger counters can’t detect alpha emissions only daughter particles, beta/gamma radiation of the U ore sample which is not the fault of the seller. Additionally, only have one GM tube [example of an entry level radex or GQ-GMC3...(300/320, below <500 which has 2 tubes, 1 specifically for reading low-level beta/gamma emissions), a entry level gmc320, or gmc300E or gmc300+ isn’t going to be able to detect alpha at all, or be accurate at low levels anyway. Even the 500+ @60seconds is +/-5%. Not really the fault of seller, more the novice detector + end user misunderstanding. Just saw this review + felt the need to clarify for anyone out there who is new to this & may get confused.
