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 I get that you want a reference source, but in case the thing actually works, you might be able to trigger it at an antiques store that handles Fiesta ware and the like:

If you know anyone in surveying, some old surveyors' kits have (or at least had) a radioactive source, and a potent one.

Want to check if your freshly-assembled MightyOhm Geiger Counter kit is working? You’ll need something radioactive! But why pay over $100 for a professional test source when there are plenty …
