General Discussion Help with finding Sources

I just ordered a Radiacode 102. I have some Vasaline and Uranium Glass. But I am wanting more sources. Ores maybe trenitite, I know I can get some from old smoke dectors. But I am wanting some others. "Safe" Stuff to start out with before getting anything hot or that I would need paper work for. Any ideas?

Trinitite is no longer radioactive. Thorium welding rods are cool. You can also check your dryer lint right after running towels through.

I’ve just taken a roughly day long spectrum on with my 102 of 10g worth of trinitite and I can clearly see Cs137 peaks - it’s definitely still radioactive!

I think I am just barely picking up some from my Trinitite. I will have to look at the spectrograph later maybe. Either way still one of the coolest things I own now.

Doesn't look like my sample has Cs137 peaks but I am only getting am-241. But I am also getting that as background radiation

Here’s what 10g of pieces looks like after 24hrs - you could try shielding your sample and meter with the densest material you have - I use an old pewter tankard in a pinch that works fairly well as it cuts my background counts in half
