Some rocks such as granite tend to have above-normal concentrations of certain radioactive elements, particularly Uranium, Thorium, (and their daughter isotopes) and Potassium-40; but not all granites are equal. Some are benign with no discernible activity (with my meter at least), while others are quite active!
I live in the state of New Jersey, USA, all granite sampled here is imported from elsewhere. As a challenge to some fellow radioactive enthusiasts out there, go find some granite tombstones (during the day) and make a video response demonstrating their activity, to see if the trends of one color being hotter than the others is the same nation/worldwide, or if any kind of granite can exhibit marked radioactivity depending on location (which would have to do with where it was quarried.) If you do this, please respect the sites and do not show the names on the stones to prevent targeting from vandals, and definitely do not take any pieces of the stones with you! However if you find a wild granite outcropping somewhere, then go right ahead lol.
@k95c Radiation is everywhere..

hmm, I do strange things most of my time , but measuring granit radioactivity in the graveyard didn't "pop-up" in my mind YET...

I would be inclined to agree, looking at the way the numbers on this Geiger Scout jumped around from 0.35 to 0.60. Soviets? Sure they got a lot of things wrong but disaster control, they had that nailed. They've used nukes to seal runaway abiotic oil wells (abiotic oil being a Soviet discovery) five times, and then - Chernobyl? I think they had this stuff pretty well cased out!

Haha I read the description, wild granite.
The first thing you need to know about wild granite is never, ever get near a mother granite's cubs.
