eli5: Himalayan salt contains minerals like Potassium which give it’s Pink Color. Does that mean that a chunk of it would be radioactive to a small degree, like a banana?

As some one who just owns a Geiger counter for fun. I will say almost nothing that is trace radioactive is even worth caring about. I tried bananas, nuts and fish. Nothing really adds more than 30% of my very low background rate. Now taking it to the beach was a different story saw almost a 3 fold jump in background from like 12 clicks min to 30+ that’s because granite sand has a little uranium and it’s fission decay products are much more likely to be detected when they aren’t stuck in a giant rock. The other place I saw a notable increase is hepa filter’s around 7 clicks min after a few months use. People are too I add 2 clicks and my wife adds 3 in-between us in bed gets 4 extra clicks per minute. Also found a rock in my basement that adds 12clicks but only if I leave the counter on said rock. Ps I would gladly bring that rock up and sleep with it the cancer risk is negligible at that level.
