Experiments, technical reviews and some profanity.
I live in southern China, when the COVID-19 pandemic hit, many of my friends left China. So, I started this little channel as a way to keep in touch with them. My first videos were about the situation in China and were all showing the area around where I live. After that, things have grown a bit, but the objective remains the same - making friends.

With scintillation devices becoming more popular, we may see even less popularity of B-radiation. Not every producer would want to build devices with plastic/ZnS(AG)/CaF2:Eu detectors to detect beta and alpha radiation. It looks like a fun DIY project tho to build own scintillator!
very entertaining! lol! beta are pretty hot to me when doing carbon dating ! hey what about hot sexy neutron ? lol
question, I am considering buying this device, but I am a complete noob to this sunject, Is there any table or other handsom information where i can compare the readings of this device so I can know what is safve and what is dangerous?
Thanks for the feedback! Typically, its not just dose rate, its total amount of dose that causes trouble. In other words dose rate multiplied by time. I know that's not terribly helpful but another way to look at this is look at the background (typically 100 to 200 nSv/h). This is safe for a literal life time, put simply you cannot avoid it anyway. If you take a long haul flight, you will be exposed to around 30x that but only for the duration of the flight. If you have a chest x-ray, you will get a dose rate of around 100000x background but for a fraction of a second. There is a useful chart here that you can download. www.acr.org/Clinical-Resources/Radiology-Safety/Radiation-Safety I hope that help to answer your question?
@@project-326 Thank you
I just want to say that no robots were hurt or damaged in the making of this video. All stunts were supervised and approved by PETR (People for the Ethical Treatment of Robots) and used highly skilled 'stunt bots'.
Thank you, the stunt-bots were really cool to hang out with on the set.
Another fantastic video. The 'graphics' were scientifically outstanding!
Thank you kindly!
WTH? is living in China good? how?
Thanks for the feedback, it all drives the algo... Well, its one of those things, I could spout on about why I think it is better, and preach (never a good thing). We could have a long conversation about freedom, idealism verses pragmatism, but frankly that isn't going to help anyone to learn anything new. My only advice, next time you are considering an overseas holiday, perhaps add a couple of days to visit here and see for yourself. Love it or hate it, at least you will have seen it first hand.
I don't get your intended audience. Things happen pretty slowly as does the narration. Some of the language makes it not suitable for school. Why do that? The subject matter should have much higher views.
Hi Charles, Its because everyone needs to do something different, otherwise life gets very boring. As of today, 7859 subscribers think that different is better and given that this is a fairly new channel, that is not too bad. Anyway, thank you for your feedback, agreeing to disagree is the mark of a civilized conversation. All comments are gratefully received, with the exception of hate speech and deliberate disinformation...
where is UV? my beloved UV!
UV will be back soon, I'm sure she will be pretty hot too! Tks!
What the... why did you change the thumbnail? 🙂 The theremino software looks quite useful, sadly the cmos of your webcam is recessed in the housing. Would be nice to get the source even closer, to not get "ripped off" by the inverse square law.
I didn't change it, we have two thumbnails running a YT experiment test. I'm sure you saw a couple of months ago that new concept being advertised to content creators? I know what you mean about getting closer, but for this source, its not really necessary but rest assured, later we will be trying some other CMOS sensor experiments and might need to get closer. Have fun with the Thermino software, it is a pretty interesting concept with more uses than just particle detection... And finally, I want to thank you personally for the inspiration to add the "seeing beta" experiment to this video, you reminded me that I had already done this experiment 6 months ago, thank you! I hope to be seeing more videos from you soon!
@@project-326 Thank you for the kind words. I wasn´t really aware of the "two thumbnail experiment" so i thought i was trippin :)
Love your videos. I've heard people complain about the robotic voice, but the sarcasm delivered in that tone makes it so much funnier. Oh, and yes please, would love a video on some bremsstrahlung experiments.
Don't worry about the haters, Arthur has a words for those folk, call sign foxtrot-oscar... I'm gonna have to dream up some interesting brem experiments.
I had a ZX80 !! Love your work !!!
My personal history was ZX80, then ZX81, followed by BBC model B. Once you own a Beeb, you will be a hardware engineer for life that has a strong background in firmware. Elite was the best game every made, even Arthur agrees!
Beta; often disguised, also uses the names, e-beam, Lenard ray, and positron. Always bring x-ray to the party too.
x-ray. Hmmm, sweet!
Can you use your spectrometer on bremsstrahlung radiation, and also the sparks that are generated in the air?
thanks for the feedback! I'm planning to measure the spectrum of the Brem in a later video. Yes the sparks were generated in the air, but I am based in a tropical region of the world, so need to be cautious on the distances.
@@project-326 I didn't know that regions of the world would have something to do with how dangerous the sparks are? Can you elaborate on that? I meant, can you also use your spectrometer on the sparks? Because I, for once, thought that it was due to blackbody radiation but I believe we should see discrete peaks if it's due to recombination of electrons. It would be interesting also to compare it with the radiation that is due to the burning of butane (generally in gas cylinders in India), in that case, it's due to blackbody radiation. It would be a nice demonstration of two different process though which light is emitted.
@@jayrashamiya2810 I just mean that in higher humidity, the normal assumptions about the distance to ionize air are not the same, ie the HV spark will occur at a lower voltage.
You rang? lol
I’ve started looking around for my own radiation check source for both beta and gamma. What are cheap ways to go and how do I treat my objects safely? Yes I’m a click whore but I would like to play with a cloud chamber and more.
For check sources, it's often best to look for old military counters on the second hand market that have a check source included. Sr-90 (a beta source) is the most common, Cs-137 (gamma) is pretty hard to get hold of these days. Am-241 from an ionization chamber smoke alarm has a few weaker gamma lines (29/60 KeV) as well as the predominant alpha emissions. Am-241 buttons from a smoke alarm will give you a source to test pretty much most counters. As for safety, for small sources, distance is the best shielding. I have a lead container and keep it in a small safe away from anywhere that I normally spend time. in terms of distance, anything over a meter is fine in terms of a good distance from your stored and shielded samples. always try and keep the Inverse square law is on your side... A cloud chamber does sound like fun.
Awesome! This is a great demonstration of the properties of electrons via beta minus decay! I have a couple of fairly strong Soviet-made Sr-90/Y-90 sources, but they're probably only about ½ to ¼ the activity (at least from what I can see) compared to the the PLA Type-77 sources. I'd like to get a Soviet DP-2 radiometer Sr-90/Y-90 source, but they're very expensive, and difficult to find. I just love the demonstrations! Except for the first demonstration, I've done these myself, too! Radioactivity is such a fun subject-with knowing the many risks it can carry! There is also another demonstration you could do, but you would need a pancake-type G-M tube and a C-14 source. The phenomenon is called "skyshine." I put the C-14 source (facing away) on top of the LND 7317 G-M tube (well, on the protective screen). The 156 keV endpoint energy beta minus (electrons) can't penetrate the back of the thin plastic source holder, however some beta radiation will scatter off of the air, and back into the G-M tube. Of course, denser materials-like lead, will deflect more of them-with a greater beta-flux density. It also has an activity that's high enough to produce scintillations in the dark on a ZnS:Ag screen, which many will say-only works with alpha particles. So, C-14 works really well, but you have to it at near-contact to get scintillations from the ZnS:Ag screen. It's also much safer, too. C-14 will only penetrate ~ 20 cm of air. The C-14 source I have is 10 μCi (370 kBq). It has an extremely thin Mylar window-on the active side, which provides excellent emissions. I really enjoy your channel, and the humor that comes with it! I love the little robot, too! Keep up the awesome work, and cheers from the USA! P.S. I recently bought a Bosean FS-5000 for ~ $48 from Aliexpress, thanks to you! It should arrive in about a week or two, hopefully with the J321 G-M tube! I figured it would work well for my hotter sources that overflow my SEI Inspector USB, but without dropping in counts, or dropping to zero, like the Gamma-Scat! I'm surprised yours somehow survived that EMP! I'm rambling now, but anyway, thank you so much! Have a wonderful day!
Thank you for the comment, rambling helps the algo and frankly it was all useful information. I have a good ZnS:Ag scintillation plate, I can get a very feint blue glow from alpha (half a dozen Am-241 buttons) but I don't get any response from this Sr-90 beta source, even in direct contact and with long exposure photography. One of these days I will take the plunge and buy a reasonable detector that has a good pancake detector, but need to save the pennies for now. Where did you get a C-14 source from? I will look into Skyshine.... I hope you have a good experience with the FS-5K, for a cheapo device, it's not too bad. It doesn't have all the flashy features but kind of does what it says on the tin.
In my tiny knowledge, bremstrahlung radiation happens when a particle experiences acceleration. So wouldn't your magnetic deflection have produced bremstrallung photons? BTW, gotta love Posh Arthur!
thanks for the interesting feedback. As far as our limited understand goes (and that is one of the reasons we want to conduct some more experiments) Bremstrahlung emission happens during inelastic scattering, ie when the charged particle loses energy (ie decelerates), the magnet that did the deflection didn't take (or add) any energy to/from the electron. So, I think this is a case of elastic scattering, rather like the the example of beta back-scattering (not sure if you saw our video on that on the channel). I think that the electron needs to actually strike something with mass to release Bremstrahlung? The main reason we do these experiments is to show what WE have learned, more of a learn-with-us, instead of a pupil/teacher relationship. So, please to keep up with the interesting questions, the mind needs good questions to be able to find new answers.
Actually you're right about this. Besides the fact it's called bremsstrahlung, every change of the electrons trajectory releases bremsstrahlung. The scattering within matter is just a side effect, bremsstrahlung can also be released in a vacuum by applying a strong enough electric/magnetic field. So acceleration/deceleration as well as change of direction (which is also change of the acceleration vector) will release bremsstrahlung:). Also not super deep into that topic but you could be right definitely. I can't tell how much x-rays would be released and my guess is that it's quite low if even undetectable. The underlying theory would support it tho and colission with matter is just the indirect cause of bremsstrahlung.
@@project-326 Thanks!
A good clean Beta source is Ni-63. Luckily the British Columbia government (Canada) used the best method of disposing of radioactive material (Ionscan 400 source, drug detector from airport security). The government sold these to the general public for less than $50 Canadian each. Had to buy one.
wow, your a lucky dude to get one of those for $50. Did you get any interesting experiments done with it?
@@project-326 Not yet, since I want to see first if I can get the machine to work. Then I will tear it apart, there is a excellent video by mikeselectricstuff (UK?) on taking one apart. The Canadian government surplus department sold me a Victoreen 190 with alpha, beta, gamma probe so I now can actually do some experiments with reliable results. It is amazing what provincial and the federal government sells at their auction sites. BC surplus was selling functional airport x-ray machines a few months back, wife said NO (-: wonder why
I need to find one of those! Ni-63 is a great, soft beta minus source! It's not as energetic as C-14 or Se-79, but definitely more energetic than H-3 or Re-187. I do know that the LND 7317 (500 V) and LND 7311 (900 V) will detect the endpoint energy (67 keV) beta particles of Ni-63. I'm curious as to how low the energy-to-activity ratio would be for certain mica-window detectors-using low-energy beta minus only sources. So far, at least for me, ~ 50 keV is about the max it will detect, with a "decent" efficiency. For the LND 7317 and LND 7311, the efficiency for C-14 is ≈ 3%.
How refreshingly political incorrect your presentation was, it should irradiate the snowflakes. Love your style......
yeah, certain sections of the robot community is up in arms about it. I had to promise that I would give equal treatment for 'sexy male' robots in a future video. Arthur isn't happy about that...

I appreciate that!
I was hoping you were going to combine the magnets and electric field with the image detector.
its all electromagnetic I suppose... :-)
@@project-326 I mean one at a time to influence the distribution of the dots on the sensor. You could put the beta source on the end of a sealed tube to give it some distance to have an effect. Then set up a electric field with your HV generator across the tube. If you wanted a longer tube you could evacuate the air.
Does a mobile phone contain a 3.6eV beta particle source?

Poor robot has to suffer so much during this video 😎 Perhaps the electrical deflection would have given more of an effect with an aperture in front of the detector, especially since the divergence of the beta-beam from the sample seems to be quite large to start with.
Thanks for the feedback. No robots were harmed in the making of this video. The issue with deflection, using an electric field is that the electrons emitted by the source, start off with an average of about 800 keV of energy, so deflecting these with 8 kV isn't going to do much to them. Over a period of about 6 months, I have repeated that experiment with 3 different arrangements to try and find just one that would show some kind of results...
@@project-326 yes, they start off with this energy, but as you stated yourself, they also quickly loose energy in air. But of at an energy of 0.8 MeV the range in air is about 3 m, which means they don't loose that much in their first couple of cm. Still I believe that you should see a difference if you used a narrower baffle at the source and a slit at the detector.
Thanks for these amazing videos. Could you test out an older app that works on the same principle as the Theremino particle detector program? The app is for android it is called: Radioactivity counter it is made by Rolf-Dieter Klein. The app is preatty old by now but it still works. He has a youtube channel with an older video of the app working @rolfdieterklein.
Strange... Beta is the most mysterious one! And much interesting with antimatter and all! I really likes this video. Very well done! I am much intrigued by the webcam and theremino rig!

In the 90’s running up to 2000 cobalt 57 was extensively used for detecting B12 and TSH assays in the medical testing field. However it was tedious, requiring a ‘hot room’ with swabbing nearly 10 surfaces including the door knob with every batch of 100’s of daily tests. Once electrochemiluminescent tests came on the market it wiped out this beta emitter test.
There was quite a lot of measurement application that was 'beta powered' back in the day...

For a cost effective and sensitive a, B, y detector gm tube I think the Passport SI-8 is a phenomenally great value at $75 USD.

Thanks for making betas hot again! I noticed in experiment 1, the dose rate kept increasing as you raised the high voltage. Why was that?
Thanks for the feedback. Yes, experiment #1 (sigh). I ran that one several times, with different configurations over a period of 6 months. More work went into that one than the rest combined! I have hours of footage from all of those experiments. Yes, there was a slight increase, but I also tested with the electric field reversed and the same thing happened, so its not actually a deflection taking place. I think that either the high electric field is partially ionizing the gas in the GM tube of the counter, or perhaps messing with the counting circuits of the crappy Gamma Scout.
Thanks! I relay your nice vdeo. OK for the experimentation with X rays !
Glad you liked it!
demanding experiment, you may try to demonstrate the bremsstrahlung by different atomic mass materials, as used Wolfram in RTG tubes for best effect. You may compare the resulting gamma to aluminium. Also as the applied voltage makes angular distortion of radiation, the angle may possibly be used as measure of electric field. Static electric fields are more demanding to measure as they do not cause inductance like alternating. Still it may be exciting the effect of positrons on free radicals. Good luck!
the issue is going to be that the spectrum of Brem is going to be determined by the energy of the incident electrons, I'm not certain, but I think that the target material will likely just cause a small spike from inelastic scattering. But maybe that is a good thing to show as well!
Great video man, i would love to watch a video on the topic of the funny word i cant spell. Keep it up.
Noted!
That video is just utter BS.
Instead of just stating that, giving reasons and maybe even suggestions would not only be helpful, but would distinct a comment like that from pure subjective negativity from well-founded criticism.
@@leandroebner1405 Who told you that pure subjective negativity is forbidden? Haven't you noticed I express MY opinions, not yours. My opinion, in this case, was sure purely negative. And opinions, by deafult, are OF COURSE purely subjective. Would you like me to express MY purely negative opinion about the level of your smartness? 🤣🤣🤣
Beta = Booba. Some B+ experiments would be neat, at least for the street cred of saying you're playing with anti-matter.
nice idea
F', marry, kill. I would F' Alpha, Marry Beta and kill Gamma. How about you? I love "Bot boy"!!
Ngl, I would date beta Love all the beta focused experiments and a few ideas for more beta experiments. You could use a radiacode or kc761 or a cloud chamber or maybe figure out how to make a beta battery using strontium 90 just as a few ideas for future projects and bremmstralung projects using lead or tungsten and using a radiacode to see the spectrum from bremmstralung would be interesting Honestly, I'm not surprised the gamma sh*t is weak to EMPs Love your work and keep it up
Funny you mention the beta battery concept, I tried this quite extensively and got no results. The issue is that you can't just use a normal PN junction for this, its a very special semiconductor 'sandwich'. There is a British twat (forgot his name) that has a video where he put a AM-241 button next to an NPN transistor die and claimed it was a beta battery - complete BS...
@project-326 Why not convert it to light using a phosphor I saw that video, and it hurt me on a personal level hearing alphas called betas, but it's not like a million people are making interesting videos on radiation like other topics like gaming or sports so hopefully it sparks another youtuber to make a similar video
@@The-One-and-Only100 That's a very good question, something I considered some time ago. The fundamental reason that my brightest Sr-90 source cannot light even a really sensitive phosphor is that although the electron energy is high, the number of electrons is tiny, compared to a really low current in a CRT. If I assume that my Sr-90 source has an activity level of about 50 uCi, so I will probably get about 20uCi on the window side, it is just sooo many orders of magnitude less electrons than just 1uA of acceleration current in a CRT. I tried with a ZnS-(Ag) fluorescent screen and it was a total disappointment. I have a small LYSO crystal arriving tomorrow, but I think its beta sensitivity will be close to zero.
Beta particles are cool to watch in a cloud chamber with a magnetic field. You can see them spiral.
We have really been wanting to build a cloud chamber for a long time, but something always seems to get a higher priority...
@@project-326 make a simple one with dry ice
Well they're called BETA particles for a reason. They are pathetic losers in comparison to the GigaChad alpha particles. Alpha Chads also dominate weak gammas, obviously. Posh Arthur, you are simply very confused and none of these are female robots. They are all male and you need to accept reality as a fully gay robot. You are very smart, so it is surprising the 3rd leg reference seems to have gone right over your head! 🍆🤖
Ultrasound blaster can be used as UFO thruster?
It moves back and forth. If you put some one way vents on it, then maybe, just not in outer space, since there isn't enough air.
of course!
I wanted to buy it today, thanks for review! I prefer more modern products like Radiacode/Raysid but wanted to get an additional meter for alpha radiation (just a hobbyist), so will probably get sth cheap or build one myself.
Alpha tubes are really expensive, it drives me nuts that I can buy a fully fledged gamma ray spectrometer for the price of an alpha sensitive Geiger counter... If you get the Raysid, please do let us all know your thoughts on the device, I have not tested one of those yet... The form factor is great.
@@project-326 True, I think I’ll get Raysid. I’m lucky to be Polish, Raysid is produced in Poland and there’s one second hand offer for 420 EUR. I can make a blog post to compare it to my 103, as a hobbyist.
Did you add the 100nF cap in series with resistor or only the capacitor ? I tried first 2.2K and the sound was weak, then I replaced it with 100n cap. and the sound became even weaker, now I'm running with 2K, but the click sound is still very weak. P.S. I ordered mine from aliexpress and it is with M4011 tube, google said it's the same spec. as J321.
The sound isn't the loudest, but there is a better solution. In this video I used only the cap. If you look on this channel you will find a video about a FW upgrade, which give very decent volume level clicks... You are correct, there is almost no difference between the M4011 and the J321. I hope that helps!
Stand on your front porch. If you go from pale-skinned to sun-burnt in .5 seconds...it's probably a nuke. There, I just saved you $180.00. You're welcome.
Uses a CdS cell with a x ray intensifier screen for a detector? That is purely garbage. Even using a naked pin photodiode would be better.
The original Russian one was decent. It dis more or less the same thing and the battery could be changed. A 10uCi check disk would get it to beep and was loud enough to easily hear it. It was only for detecting dangerous levels of radioactivity and also was only 25 bucks😂 180 bucks could get a decent geiger counter.
The Russian one used an actual GM tube, so it really worked with gamma... Thanks for the feedback!
For years I had planned to build one of those grating spectrometers, but I wanted to build it to higher quality than most of the ones I had seen in the internet. Of course that led to me never even getting started, until I watched this video and another video promoting the same product. I decided to give it a try - it arrived today and I can only acknowledge that it is a pretty decent piece of hardware. I immediately ordered a second one for the office.
Fantástico.
