Escaped Artificial Radiation is caused by industrial by-products, of fission reactors, weapons manufacture, mine tailings, etc.
Natural radiation is normally not concentrated, in rock, in escaping Radon gas, and from outer space.

radiation detectors | encyclopedia
I purchased a radiation detector 2018. It takes some time to record local level, because normally radiation is weak and stray counts are scarce. I live at about 550 ft. elevation, and readings are usually 12 to 14 μSv here. Ambient radiation increases with altitude and proximity to other environment sources.
