Nice collection, there are several people here that collect radioactive elements and things, I remember a thread about it a long time ago. The only thing I have are some uranium glass marbles.

Interesting. When I was a Nuclear Reactor Operator in the Navy one of the places I was assigned was a ship tender and was in charge of nuclear waste material and nuclear maintenance and received enough radiation that I wasn't allowed near it again for a long time. Went to a specific school for it. Shipped the waste material to a holding facility. Trust me, it was a big deal. We had a lot of different radiation detectors and none of them were as simple as that. Ours looked like something you would expect to see in sci-fi movies. Was medically retired in 96 and let all that information drop out of my head. Did a lot of things other than just sitting in a chair and controlling the reactor. Odd for me even to think about now as I was in from 86-96 and it practically feels like it never happened.

My friend, Seoul_lasers is looking for a source for some Cs137. If you know of any, you might send him a PM. Thanks for sharing.

If he is in seoul hy might find some a bit up north, say where the north koreans did nuclear tests ;)

I doubt you'll find much of it otherwise. There are very limited practical uses for the stuff, and due to its biological dangers other isotopes are preferred when possible at all. It's only produced in nuclear fission reactors and -bombs, and even used to date things being produced before or after the WW2 atomic bomb (tests).

Actually, he's in Canada, but needs the sample because of a gamma spectrometer he's built and is testing the spectra of the radioactive decay of different isotopes. He has a thread I've been following from 3/2015.

Nice collection :) I recently got myself an old polish Geiger counter from eBay, but the only things I have is some Uranium Glass, Tritium and an unknown beta source that mysteriously came with the Geiger counter. Strontium-90 sounds like something I would like to own :eg:

If you only need them as calibration or experimentation sources i'd suggest just getting some disk sources, perhaps from something like united nuclear. These will probably cost you around $100 a piece for common isotopes, which can be good value compared to any other source.

These sources should not be that hard to obtain really, they are commonly used in training to get certification for working with radioactive materials. I remember using several different ones when i did my certification course, some emitting only alpha and some a combination of beta and gamma. Point of the exercise is to determine what isotope it is (from a list of options) based on how well a certain material shields the radiation and such.

Tritium would probably not be an interesting isotope when working with geiger counters since it only beta-decays with very low energy, trapping the emitted electrons in even the thinnest of enclosures (tritium in a glas vial cannot be measured because all the electrons end up in the glass).

Re H3; you can't measure the betas (at least I can't, and most others can't), but you can detect the bremsstrahlung if you have a low energy sensitive detector.

OP: nice collection. Nothing particularly hot here folks, so don't worry about exposure rates.

Click to expand...

I'll second this. Nothing really that dangerous. The Am241 is about as hot as you got there. It's probably 0.9uCi which is miniscule.

Beta "can" be measured via BCM420 highspeed scintillation detector plastics.
It requires a pretty fast discriminator and large amplification or very large PMT say 2.5-3"dia. H3 is pretty difficult to detect through the glass envelope.

BUT....

* Usually to really get a good measurement for H3 either HDT-He process or via a large area 2-3" high speed solid state SiPMT with CaF2/Eu doped crystal to get a proper reading in industry.

Ordinary geiger counters cannot measure the low energy beta's from tritium. There are 'windowless' and some pancake sensors that can though, albeit it a price. If the tritium is contained in a vial there is no way to detect it regardless of what sensor you have - the wall of the vial stops the electrons and at such low energy brehmstrahlung probably is hard to detect either.

If your budget of a detector is $1000 or so you might just want to forget measuring tritium at all. It's not that interesting an isotope anyway.

No you are right about the beta radiation, but I also have a sensitive gamma setting which will detect even low energy gamma rays. Tritium does emit low energy gamma rays that I have detected but again it is weak. I will probably look into getting myself a disc source. Thank you.
