Does anyone in #Philly have a #radioactive source that produces X-ray/gamma or beta #radiation, or know where I can visit / borrow one?

I bought a geiger counter alternative on Kickstarter, and I have no idea if it works. I could buy radioactive test material, but then I would be intentionally creating the situation I am trying to avoid: radiation in my house.

So I want to find a gamma or beta radiation source not in my house, to test my radiation detector, but I don't want to keep it.

@skyfaller Molecular biology labs and/or Chemistry labs usually have something around. Naturally occuring uranium salts don't even require containment (much to the distress of my lab mate who found out that our alphabetically organized chemicals had put a bottle over his desk for years!). But beta and gamma emitters are common, and while nobody would lend you a sample, they would let you put your counter next to theirs while pointing at it!
