Very nice! This is a great video! I've never had a chance to measure Cm-244 and Np-237, but I have with the rest of the radionuclides that you use. Pu-239 (and/or Pu-238) doesn't show up well on a gamma spectrum, due to its very low branching ratios of low-energy gamma rays. Even with a high-grade spectrometer, it can take about a week of measuring to develop a spectrum. Plus, it decays to U-235, which does emit some gamma rays of various energies. However, U-235 is also far more stable (t½ ≈ 703 Ma), making it pretty much impossible to detect and identify. I also have a source of C-14. It doesn't emit gamma rays-at all, however I can detect (or see) it with an alphascope/spinthariscope-at contact-in the dark, and of course, my SEI Inspector USB G-M counter can easily detect Pu-239 (211 kBq) and C-14 (370 kBq). This is a great video, and I don't even have a _RadiaCode_ detector. What are your thoughts on the _SEI Inspector USB_ G-M counter-if you've used it? It has now been replaced by the _SEI Ranger,_ which is very similar. I think it's an excellent digital G-M counter! I got it brand new-for really cheap, too! Thank you very much! Cheers from the USA!

@@KarbineKyle 211kBq of Pu-239 is definetly more than we have in the lab. I think scraping everything together I might find 3kBq but from all isotopes: Pu-239,40,42,44😅 The radiacode is the first detector for private Person that I used. Since I work in a nuclear lab, I don't have to buy (expensive) detectors, as I can (thanks to my super chill Professor) just use our lab equipment ;D I'm sure there are other people with way more qualified opinions on these detectors on the Discord server (linked in the seminar series Video description)

[@KarbineKyle]

Thank you very much! I really appreciate it! I'd love to see a possible future _RadiaCode_ model that uses a CeBr3 scintillation crystal, or a CZT semiconductor crystal! That would be awesome! Radioactivity has always been fascinating! I'm glad that I got extremely interested it ~ 16 years ago, and it became my main focus-to this day! It's always so great to see others with shared interests just enjoying what they love! Thanks a lot! Cheers!

[@WR3ND]

14 days is the magic length of time for a full measurement sample on this device.

[@donaldhoot7741]

I've got one. It's fun to play with and is pretty amazing!

[@antigravity8247]

Wenn du das Smartphone um 90° drehst, siehst du das Spektrum wesentlich besser. Turn the phone 90 degrees!

[@GigsVT]

The gamma from an alpha emitter is usually low energy gamma caused by isomeric transition as the excited daughter products return to ground state.

[@SimonsNuclearchemistry]

Can you Name from which Isotope the Gamma came? ;D Am-241, Cm-244 or Np-237?

[@GigsVT]

@@SimonsNuclearchemistry americium has a low energy gamma peak

[@Havron]

Simon, can you do a video comparing the Radiacode to the Raysid? I have the latter and I love it! I am wondering which device you would judge is better overall, and in which ways one or the other is superior.

[@Adiki3]

Maybe try to compare Radiacode to RaysID, especielly with efficiency for higher gamma energies.

[@SimonsNuclearchemistry]

Would love to^^ maybe they also send me one hehe

[@terrydavis8451]

I want one soooo bad.

[@wakkowarner7391]

Go on, treat yourself.

[@Adiki3]

3:50 Pu-239 will have a contamination of Pu 240 enough to have some gamma emission. Unless you have obtained a supergrade or at least weapon-sgrade plutonium :) Well, probably you have :D

[@SimonsNuclearchemistry]

Yeah we have a fairly pure Standard but there are traces of Pu-238 and maybe Pu-240 but traces from 800Bq is equal to basically zero😅

[@Adiki3]

@@SimonsNuclearchemistry Checked the branching ratio of Pu-240, looks like I was mistaken by a zero or two... possibly in the long term it could show, Though I wonder if it could be possible to check alpha activation of aluminum...

[@SimonsNuclearchemistry]

@@Adiki3 Alpha activation of aluminium? You mean the nuclear reaction that produces neutrons from Aluminium? I could Cover that topic and say a few Words but the RC-103 won't be able to detect these neutrons

[@Adiki3]

@@SimonsNuclearchemistryNeutron would be hard to detect, sure - but resultant P-30 should undergo a ß+ decay, so we would get 511 keV gamma photons if I recall correctly...

[@SimonsNuclearchemistry]

@@Adiki3 no😬 the P-30 in this nuclear reaction isn't comparable to the ordinary P-30 radionuclide. During this Alpha,n reaction the P-30 is a compound nucleus. They are VERY high energy Versions that only last 10^-19s. Same with the C-13 when talking about Be Alpha,n. This C-13 isn't the C-13 we know from NMR Analysis :D

[@thesciencefurry]

I have the radiacode for a few weeks rn and I'm pretty pleased with it. I'm interested if the "activity" function is any accurate. You can put a point source 5cm in front of it or put it into a marinelli container. Maybe you can make a video testing that?

[@The-One-and-Only100]

I have a radiacode 102 for months at this point, and I still couldn't figure out how to set up the different options for the activity function (or where to get a marinelli container or food or water contaminated with cesium 137)

[@thesciencefurry]

@@The-One-and-Only100 Yeah I was wondering aswell where I can get the containers. It would be great if you could just 3D print them aswell. But the point source option should work without a container.

[@The-One-and-Only100]

@thesciencefurry I don't have a point source like a needle source, but I wonder if a button of americium would be considered a point source if it's an umbrella term for sources like disk sources and other small sources

[@thesciencefurry]

@@The-One-and-Only100 I would think a point source doesn't have to be an actual point. But that's a thing to test with the Radiacode aswell.

[@dg0mg]

Have in mind: The Activity-Function only works for Cs-137!

[@ShawnC-sn1mz]

Could you please post a link to the programs you recommend to use along with the 103?

[@SimonsNuclearchemistry]

Will do so :D I also forgot the Word and Excel document😅 I will answer you, when I implemented both^^

[@SimonsNuclearchemistry]

wouldn't mind^^ but not planned for now

[@Muonium1]

There is another channel on here claiming x-ray fluorescence spectroscopy is possible with this device but I really doubt it and think it's probably overinterpretation of the data. Maybe you can test?

[@SimonsNuclearchemistry]

Its possible for some high energy lines. You can see Cs X-Rays but I would rely on it. To be fair thats clearly not the use it was intented for. The channel Resolution isn't high enough to make good statements. Will go further into it but first I should make a Video about classical XRF and X-Rays in Nuclear chemistry ;D

[@The-One-and-Only100]

I have a radiacode 102 and I tested out what pyrotecnical did and I saw silver xrf (I don't have enough of other elements to test it out) the experiment was simple just have your radiacode behind lead have the target within eyeshot of the crystal and the source (I tested with americium and radium and americium worked better because it was cleaner at the under 100 keV range)

[@osmanfb1]

could you show a link to site with a gamma ray spectrometer that costs 100 EU less? Thanks.

[@SimonsNuclearchemistry]

I meant more like: if you know electronics, you might be able to buy a NaI(Tl) Scintillation Crystal and with knowledge, transistors from Alibaba and stuff like that, one might be able to get all the parts for a bit cheaper... all scraped together 😬 as you can read: I am not the kind of person, who knows that kind of stuff.

[@michaelborsato2092]

Theremino Gamma Spectrometer is completely DIY, an italian project. Buy good 2'' NaI(Tl) probe and connect all to the PC.

[@bazhdarnooraddin]

would do mind tell me what range of dose rate is?

[@SimonsNuclearchemistry]

I don't understand the question

[@bazhdarnooraddin]

​@@SimonsNuclearchemistry thanks, I mean does range of the dose rate of radiacode 103 starts from 1 microsevert/hour to 1msv/hr or from 1 microsv to 10 msv/hr ?

[@SimonsNuclearchemistry]

@@bazhdarnooraddin it starts below 1uSv/h and the Display on the device can only Show values up to 1mSv/h past that it states ">1mSv/h" but in the app you can definetly values up to 20mSv/h. I can't tell you more, as I don't use it that often 😅 I'm sure there are people that use it more often and can tell you more. But 0,1uSv/h to 20mSv/h is measurable with that

Nope ;D there where two samples. It doesn't show counts with the pure Pu-239. But it does detect something from the mixed Alpha source: Am-241, Np-237 and Cm-244
