So you get your geiger counter and shortly thereafter you get bored because there is nothing to measure. Then naturally you begin to wonder if it really does anything at all. A simple circuit could generate random chirps and flashes. How would you know? I was mildly surprised to see that this was available.
My sample came verified at 1150 CPM. My Mazur GC reads it as high as 5K! Definitely got what I paid for. I also like that it comes verified for a Beta & Gamma (no Alpha) level as well. Most of the cheaper GC's do not read Alpha so if you have one of those it's nice to know what reading you should expect in that application.

Just to make it clear for everyone...here are pics of what you'll get...
I have to admit that I misled myself on this purchase. The closeup of the metaloid container that ships with it didn't help. I was thinking that container was larger than it turned out to be and that it was a container designed to provide shielding of radioactive materials. I wasn't aware that a small, gravel sized piece of rock with a ho-hum cpm could fetch about $50. Now I know. I took pics of everything you'll get and I included a penny so you can get a good idea of the scale. The container is made of a substance that's at least part metal. It's the thin metal used in holiday candy assortments and such, with a sticker on it. They packaged the product well and shipped it in a timely manner. I don't actually think it's a good value for $50, the sample you get isn't especially radioactive and it definitely isn't large. Or medium sized. It does come with a homemade, official looking certificate which swears to the value of your newest acquisition's cpm. If you don't have high expectations this is a well rounded type of gift.

So after a few weeks I finally had the balls to open the container and see what's inside. The item came in white cardboard container which displays the radioactivity symbol and the warnings about the product, and it's probably the best part because of its semi-menacing look. Inside that container was a smaller metal container which was very well protected in bubble wrap and foamy things. This metal container has no labels of any kind. Inside the metal container is the uranium inside a plastic bag surrounded by more foamy things. The uranium looks just like any other little rock, and when I say little, I mean little. It was disappointing it didn't glow like kryptonite, because I don't have a Geiger counter to check it and see if it's really radioactive, so this could be just a little rock and not uranium.
So, I paid $7 for the right to say I ordered uranium on the internet, I guess, not bad, better than $40.
One thing, on the white container the warning says that the "specimen emits alpha, beta and gamma rays", I'm not sure about the beta or gamma, but I definitely feel the alpha rays because immediately after opening the container I got this impulse to drink beer and watch sports.
