A Small Update on the Ju-Ju Stickers and Such - Negative Ion Energy Ju-Ju Pt6

For all of the posts in the Negative Ion Energy Ju-Ju series, click here.

A radmon.org user arranged some stickers in a certain way around their tube they managed to get around 4300 CPM. So I tried too.

I managed to arrange nine of my stickers in a similar arrangement as Mercator and I get around 4200 cpm also! It peaked at about 4218, but is mainly around 4100.

I'm impressed for some cheap stickers! Excellent check sources. 😄

nzoomed, over on radmon.org, asked about a gamma spectrum, to try and identify the radioactive compound in these items.

I only have a Radiacode 101, which whilst it does something, I don't consider this to be a proper Gamma spectrometer. It does give an idea though. In another post (here), I pulled some beige/light brown powder from a negative ion wand thing. At the bottom of that page is a spectrum that I got some time back. I ran the same test with the same powder over last night, so got about 18 hours or so on the Radiacode. The lin and log spectrums are below.

It is a multitude of reasons I suspect this is Thorium dioxide. Mainly much reading on the internet and watching videos. The video you posted was one that I posted on my very first post about this Ju-Ju stuff and the presenter does a fair job of identifying the products as having Thorium in them. You can buy this stuff by the barrel load from Alibaba and other places. A simple search for 'Thorium dioxide for sale' reveals many sources, of which most seem to be in China. The powder I extracted wasn't pure white, so is most certainly not pure and probably contaminated with something. It may be a simple bulking agent so they don't have to use as much Thorium dioxide. It could also be Thorium Oxide, but my understanding is Thorium dioxide is much more available than Thorium oxide, and I think much cheaper too. Looking at the wikipedia page for Thorium dioxide it states 'it is mainly a by-product of lanthanide and uranium production.' This is what I was referring to when I said it was a waste product. Maybe not waste per se, and probably a bad choice of words on my part. I just noticed then in a google search the question 'How much is Thorium' and clicking the question gave this answer: 'Exports of unspecified thorium compounds were 63,200 kilograms through August 2023 with average unit values ranging from $29 per kilogram to $74 per kilogram and averaged $69 per kilogram.' That seems very cheap, especially if it can be diluted down in the resins or bulked with an agent. The ones I have seen for sale have usually been a white powder, and has usually been marked as 99% pure.

I took the (what I think is) Thorium dioxide powder from the Radiacode and have replaced it with a Thorium gas lamp mantle, which if the powder is Thorium the Gamma spectrum should be more-or-less the same. I'll leave this on overnight and see what it yields tomorrow.

And for full disclosure, I don't have a testing chamber, this is just literally plonked on a desk and left alone for some hours. So it is certainly getting some external counts. That said, generally the longer it is left (and the hotter the source), the better the spectrum. Will have to see what tomorrow shows, but looking at the spectrum (of the Thorium gas mantle) after just 30 minutes, it is showing a very similar spectrum.

Update.

It is definitely Th-232. I can't say whether it is an oxide or dioxide, but the spectrum is pretty much identical to a Thorium gas mantle. I do think the calibration is a little out on my Radiacode but as the spectra are the same there is no doubt it is Th-232. My little bottle of Thorium powder is almost the same activity as the gas mantle - Thorium powder is 2.31μSv/hr - gas mantle is 2.48μSv/hr.
