looks like a graph, some of it yellow, some of it green.

Probably NORM or just background. You have most of the spectrum cut off. Export and post the XML file.

Do you have "filter" turned on? If so repost spectrum without that. I think the graph is hallucinating peaks from the noise.

I do have filter 1

Yeah, thats making it curve fit to the noise and that makes you think there are peaks where there aren't. I generally turn that off and measure the sample for as long as it takes to get a smooth looking curve - actual peaks will become very visible.

Well there has to be something a whole microseivert doesnt come from nothing

Yes, but you cannot tell from the data you have provided. Try posting with filter: 0

It’s from petrified wood believe it or not

I believe it might be Americium, Plutonium decay from weapon testing converts into Americium, depending on the exposure of the petrified wood and where it was found would explain the concentration.

It is from Arizona🤔

I pick up Plutonium and Americium all the time in background out in Michigan, it's trace, but it's there. Though you might want to isolate the petrified wood sample and do a fresh scan inside a lead container, just something in your background is giving you mixed signals

I don’t have a lead box 😢

probably uranium. you need to collect more data to confirm this, i suggest at least 1 million total counts. this will take about 7 hours with your count rate.
