Potassium Chloride Salt - Radioactive Salt

Hello Folks, It’s been a while from my last post. I’ve been busy with work, but in the last few weeks I still managed to put together a measurement. Some time ago I found myself in a conversation about food, it felt like one of those occasions where people end up taking pictures of what they are eat...

Re: A closer look at Trinitite below 40 keV

One day I will test again my Type-5 Trintite, your result is very interesting and I will give a good a read to the paper, thanks for that!

Re: Curit from the Congo

Nice sample...how many counts you got from it compared with background?

Re: Uranophane from the Black Forest (Germany)

Thank you guys. I am working on the next one, but it'll take some time. @GigaBecquerel, I can usually tell both those peaks, and often the 63 keV as well, while this time there's only a small bump there. Also when the sample is hot enough I don't use the lead shielding so I can rule out the 77 keV p...

Hello Massimo,

Thank you, now I'm finally one of the cool kids! ;-)
What do you mean by indirectly identifying the peak?

Uranophane from the Black Forest (Germany)

Hello there, Today I had some fun with this beautiful sample of Uranophane from the Black Forest in Germany. I had it for some time, but for one reason or another I never tested it, actually I quite forgot I had it, the other day I was checking the small safe where I keep some of my radioactive stuf...

Re: Fukushima Soil Sample

Welcome to the club Lukas,
i couldn't identify the first Cs134 peak in my sample with my 2''x2'' NaI(Tl), I had to do it indirectly.

An HPGe solves a lot of problems, the result is really nice.

Re: Unknown uranium mineral found in Penticton B.C. while on holidays

Really a nice find Conor,
Picking a sample in the field it's always more interesting than buying it online!

Re: Berries from the Ukraine and HPGe Spectra

Interesting, if you have to chance to find some more of these "Berries" let me know :)
Where did you get your HPGe detector?

Re: Uranium Glass – Different Glassware, Still Natural Uranium

Yeah, I think Iodine could be the right answer. Lately I've been in touch with a couple of authors of the Trinitire paper I linked in my last Trinitite thread and after finding that peak in yet another spectrum I asked them for their interpretation, because I really couldn't figure it out. Here's wh...
