Re: Spark Counter and Bragg Peaks
This is a fantastic post and I enjoyed the video earlier today. (subscribed to your channel) At the risk of asking the following question (on this forum that will make me look stupid instead of YouTube), "What is the source you're using?" (The black cylinder used to generate the alpha part...

Re: Mobile spectrometer
As for the "efficiency" of the RadiaCode I took some measurements using both my RadiaCode and my 2" CsI crystal that was shielded in my GS-STANDUP filled with Lead shot (and lined with copper and tin) and was surprised a bit by the results. Basically, I tested several Cs-137 sources (...

Re: Mobile spectrometer
Greetings ChrisqMalibu: I own and have used the RadiaCode 101 and quite like it. Like you I don't expect an iOS solution any time soon; it works reasonably well with Windows 10 and Windows 11 on my Surface Go for mobile use (though it collects data without being connected to either a phone or comput...

Re: Calibration Question for Building an Instrument
GMtubesNsample.png The easiest answer is that the source should be located (relative to the GM tube) where you expect to be taking measurements with the fully calibrated instrument. Remember that distance matters in radiation measurements. Attached are drawings of an instrument that I'm assembling ...

Re: Building an XRF detector with CsI(Tl)
Can't wait to see the spectra once you've finished this detector. Hope you'll post a price to make more if it works!
Re: Apatite
Hi Stefan - As for the paper, the first few paragraphs will answer most of your questions (the EXAFS analysis is not so interesting to me for reasons I mentioned earlier). As for the older post, what is so interesting to me is how different your spectrum was from that collected by Matthew Pickard (P...

You might also want to check out the spectrum collected by "Photon" on 16 September from an Apatite specimen that contained a fair amount of Thorium: viewtopic.php?f=5&t=635

Re: Apatite
Stefan: That is a beautiful sample of apatite and a fantastic spectrum. I was a bit supersized that there wasn't more Uranium in the sample (just from a quick initial scan of the data), but that can happen depending on the source of the mineral. Apatite is well known for incorporating Lanthanides an...

Being from Utah, and having several pieces of tyuyaminite in my collection, I'm impressed you can say and write it without Google. I still can't... I love your posts - excellent spectra and a wonderful presentation each time! Keep up the great work!
