Three Geiger Counters Challenged | Weak and STRONG samples
HTML-код
- Опубликовано: 31 май 2024
- My hottest, radioactive sample is finally measured - but also a new, unusually weak sample with tritium. Will all of my three Geiger counters handle it?
The RadiaScan-701A (discontinued) and tritium-bearing memorial (discontinued) were donated by Radiascan, which is now Radiacode:

I love how the RadiaScan releases an S.O.S in morse code, very creepy
Being the smart ass I am, I searched for "morse" b/f I was going to add the same comment.
my favorite part is when it says fuck it and just screams.

That alarm is meant to be warn when walking around chernobyl or something, to alert you when you are wandering into a hot zone.
@@RKSNomad but isnt sos ...---...
@@superzucc7343 yeah... in unsure what your point is.
That's one chicken scanner - it sends out SOS when radiated.
Peter Riis i guess that's to warn the handler to get the hell out of wherever they're scanning immediately
I hope that feature can be turned off. Otherwise I'd be very tempted to do a photonic induction on the thing.
@@plushifoxed
Really?

Nice illustration with the glowing balls
Yeah that looked really cool
I thought it was CGI lol
Absolutely! Looked like it was made on a computer until the hand came in :D
It was nice. I would have like to have seen him use blue for negative to differentiate from green neutral, but he probably didn't have blue fluorescent paint. Or the blue showed up as green on camera or something.
Why am I dirty minded
Thats one serious and very creepy geiger counter lol
It immediately sends out SOS on Morse code damn
It's a warning to get the hell out of there.
Make more videos with radioactive stuff, love it
As a Nuclear Physics student, this "home" video is truly pretty accurate
With the possible exception of needing to handle the uranium ore with such care...the biggest worry there is the radon--you couldn't get enough on your hands to cause any harm...
@@jomiar309 I mean I'd assume the worry is more about breathing in particulate from the uranium ore, not just being near it, right? It's not hot enough to be an immediate danger in the short-term but you do not want pitchblende dust in your lungs
I gotta say... That little atomic demonstration was pretty awesome.
Another outstanding video my friend

Thanks to this video, I purchased my own RadiaScan. Quite happily, the most radioactive thing I found in my house was a stack of napkins made from recycled material.
I have a GQ gieger counter, and I think it's click is probably one of the most iconic gieger counter sounds. I haven't found anything radioactive above 50 CPM on my property, but I really like taking measurements of things, and a gieger counter is one the tools that you will likely never really need, but when you do need it, you really need it.
Cool😊
I really appreciate your attention to detail and clear explanations! I hope more and more people watch your videos and learn from them. Also, your accent is very pleasant to listen to. :)
Can you please test a cathode ray tube monitor (maybe an old tv) with your new device
Thanks
btw why is the reading still at 40 µSv when you placed them on the dinnerplate at 10:57
is it due to Potassium decay?
I think it's one of his uranium coated plates, so it's quite radioactive by itself if you mean that
@@swabianscience Yes, one common brand which used uranium glazes was Fiestaware. It wasn't done for the radioactivity but rather for the properties of uranium compounds as dyes.
@@swabianscience thank goodness for the context, I was about to be scared of all my dinnerware...
@@vamp97 Even if all of your dishes were coated in uranium based glaze, it wouldn't be dangerous. The amount of radioactivity is tiny (You'd have to hold it next to you for years to significantly increase your cancer risk), the only danger is when the glaze is damaged, it emits uranium dust, which you really don't want to breathe.
So, where do you store those? In your noisy neighbor's yard?
I might put them in the middle of some water canisters to absorb the radiation.
I store my strongest samples in a 'cage' of multiple layers of concrete garden tiles outside my house. Blocks the radiation to a tolerable level :) Thanks for watching!
What do you know about ions? What can be used to detect and read how many are being produced.
@@21gioni :
Smoke alarms with Am241 measure the number of ions in the air near the Am241 source.
en.wikipedia.org/wiki/Smoke_detector#Ionization
@ louis tournas thanks for your comment but the smoke detector produces ions and reads only a disruptive molecule that reduces the ability of ions to move. It doesn’t give an actual reading showing how many negative or positive ions present.
Both smoke detectors and emergency lights contain radioactive substances and if you don’t know what you are doing best not to play with them.
Brainiac, your videos have this special kind of atmosphere / feel to it, please never change this. It's sooooo moody
I've been following you since the first geiger counter video!
So glad you're still on youtube :)
I'm speechless! Good luck in the future! The meter is singing to the user when in high levels :p
Love the visualisation of the atomic nucleus! Especially the neutrino :) It was really good and effective.
Production quality on this video was amazing. So much more work being put into the video. loved it.
Nice! I was just watching your videos, thank you for the exemplary work!
Same
Thank you, John. You certainly were here fast ;) More to come!
I like how the RadiaScan uses SOS in Morse code to warn the user.
Just like all your other videos, fantastic! Thank you and keep the good work
Love this channel what a voice!
As always a terrifically interesting and educational video! Thank you!
Awesome, I love it when you do these kind of videos! :D
Amazing video mate, absolutely loved it :)
Love your vids as always!
Thank you so much for the info! I just ordered my own Radiascan-701A
Love what your doing dude Keep it up!!!!
Hi braniac! Been watching for almost 3 years now, i think it would be very cool if you did a tour of where you store all of your samples/magnets/everything. Perhaps a future video idea?
You have a nice channel with nice videos! Really nice!
Your video editing has gotten so much more elaborate and sophisticated if you have an editor then give them my remarks and if you are doing it yourself then kudos to you and well done!
Always interesting and educational. Thank you.
Sehr interessantes Video! Weiter so!
You're just amazing. Thanks to you we can learn more about this things!
Great video mate! Subscribed!
Out of all my (many, many) subs, this is one of the few where I've never watched a video and been, like, "meh". Always interesting, always informative.
Quality content as per usual
Really fine presentation.
Great work👍
Nicely done!
@3:00 ish, that was a very nice illustration of the elements. I feel we need more of that. ;)
Great video! I would love to do more stuff like this on our page. Keep up the cool stuff.
great vid keep them coming
Like always, Perfect video :)
Du er under vurderet og fortjener klart flere subscribers!!
Elsker dine videoer! :D
Yes would like to see the battery replacement. Also any schematics that you can find on the circuit board.
Thanks for the vid.
A schematic of a turd emoji would do it justice!
"This video features radioactive items" = instant thumbs up from me!
The quality of this video is insane.
Ahhh what a cool video!!! I had to pause it in the beginning to look up antimatter and it was a super intriguing subject, and the radition stuff was really cool as well! I wish I could support you on patreon but as I only turn 16 this year that's not possible. However, if you were to sell merch, especially something like shirts or pins of your wheel of hazards I'd definitely buy something like the nerd I am XD
By the way, i have to mention it but i think i saw a meteor yesterday! I would've thought it was some sort of firework or something but it made no sound, it was a orange/yellow kinda fire colour, sparks came of the end, its soared for maybe 1-3 seconds before disappearing pretty high up but much closer than the few stars that had come out and it was the most amazing thing ever
Thank you very much, Indra. Patreon support is totally optional. It's an even bigger support to always watch, like and comment on my videos like you do. That matters more! I don't have plans for merchandise at the moment, but who knows what the future will bring. I dream of a Brainiac75 line of neodymium magnets. All grade N52 looking good in black epoxy with my yellow logo on them x) But your suggestions are more likely to be realized.
Sure sounds like a shooting star. The sparks at the end were the meteor breaking up in small parts from the extreme friction heat etc. when entering the Earth's atmosphere. Very cool display indeed - congratulations :o)
This is such a great demonstration. If I ever work at a national lab again, I'm definitely getting a 701a.
You won't
the atomic diagram was really cool and informative! very easy to understand.
Ok that was actually awesome, I extremely enjoyed watching that and also remembering that I've already watched the other one from the 2015 , you are real great and I extremely appreciated this video the radiation really does scare me I hope you stay safe keep up the amazing work that you are doing I can't wait to see your next video
PS greetings from Iran 🌷😊
Thanks, Abteen. The pitchblende sample does need to be treated with respect, but for short amounts of time near it, it's no problem. I actually received less of a radiation dose by filming this video that I would receive on an international flight (cosmic radiation in 10 km's height is a thing...). Thanks for watching once again and greetings back from Denmark.
awesome video as always!
I know it's been more than 2 years, but I'd absolutely love to see more radioactive experiments!
You are awesome! But I have a question. By looking at the working principle of a phosphor coated lamp, couldn't it be feasible to use radioactive materials for lighting? I'm just so curios.
Great video!
The Geiger counter beeping and the creepy music in the background...
Gives me chills.
Amazing!
Great video! The information about tritium is very interesting. I have one of those vials on my keychain so I can find my keys in the dark.
Amazing
RadiaScan 701A is a Russian device. I have one and it's one of the best radiometers out there. By the way, hi from Russia.
hi there, it's a geiger counter, or just a dosimeter?
@@0XAN A dosimeter is technically a geiger counter that can also count a the accumulated doese. A radiometer can only estimate the current level in real-time. Technically the Radiascan is all of that
Brian, I have 4 observations:
1. Very nice video, as always. Congratulations!
2. I found it very interesting how your new RadiaScan beeps S.O.S. in morse code, until it reaches about 700 uSv/h, when it goes "oh my god get me the hell out of here" constant beep mode.
3. I didn't understand why the uraninite was colder than the table (that was, presumably, at ambient temperature).
4. I also didn't understand why your Soeks and GammaScout devices zeroed the readings in 2015 and did detect radioactivity at this time...
Thanks and best wishes!!
tillykke med 500 tusind subs!!! håber at du får 1 million :)
Hello , where you bought the power plant model at the beginning of the video ? kind regards
Tak! Oh, and it would be cool to see you bring out the soldering iron!
Very good content 👌
Thank for a comprehensive review. As you have used that meter, would you explain what is the unit the meter uses in alpha and beta mode: cm-2 min-1. How this is related to CPM?
Nuclear physics are absolutely wicked, thanks for the awesome stuff !
thanks for the recommendation
I like how they don't have a word for Bremsstraglung :D
"Slowing Down Radiation" (SDR) or "Braking Radiation" (BR) is too long!
You should take them with you to thrift stores. There are stupendously radioactive things lying around there, mostly glazed ceramics.
Very weakly radioactive, especially compared to the pitchblende he showed in the video. There are some VERY spicy radium items out there (not the usual watches and clocks), but erm, those aren't so common in antique shops (thankfully!)
I absolutely want to see an attempted battery change. great stuff as always
I think a video on swapping the battery would be interesting. :) Good video.
That chunk of radioactive material is mad do you have a lead container to store it ???, this has to be my favorite video from you
nice, could you confirm a spec or two of the RadiaScan. Per their website it states: maximum range of radiation intensity: 10,000 micro Sv/h ( 1000 milliRem or 1 REM ) is this value for say gamma in-combination with the cover shield? Another spec has me curious : maximum range of integrated dose is 1000 millisievet ( 100 REM ). is this maximum value a counting dosage over time? is the pancake detector referenced to Cs137? ( would like to know the efficiencies, Cs137, SrY90, etc, do you know or have link to their datasheet? ). for under $300 it's interesting. thanks
I'd love to see you change that battery. How will you calibrate it though do you need a spectrometer?
woaw have I bin here for more than 4 years, time realy flies by
i just want to see moreee , i get adicted to your videos
Great video as always! How do you store that uranium oxide safely? Keep up the great work ❤
Wait how'd you get a black RadiaScan 701A; I've not seen an option for black.
To go into a bit more detail about tritium turning into helium-3, this is done through a process called Beta Decay, because when it happens, a beta particle is emitted from a nucleus [a high energy electron/positron]
In the case of tritium, a neutron was turning into a proton spontaneously. This happened because the quarks that make up the neutron are capable of changing into other kinds of quarks by exchanging a type of particle known as an Intermediate Vector Boson. In this case, it is a W- Boson, which can be thought of as a kind of messanger particle.
To avoid a whole lecture about quantum electrodynamics and field theory, the gist is that while this decay process is happening, a beta particle and antineutrino are being created in a pair. Every time this process happens, they always come in pairs.
Neutrons have a higher rest mass than protons. Essentially, it is that extra energy that goes into the beta particle and the antineutrino. There are also some photons involved but those aren't that important.
This can also happen with protons becoming neutrons. It's called inverse beta decay, and it happens whenever you have a high energy particle, usually a beta particle or high energy neutrino smash into a proton.
The kinetic energy of the collision supplies the activation energy needed to kickstart the decay process. An up quark in the proton by way of a W+ Boson changes into a down quark, and the nuclear potential energy between those quarks rises, giving the resulting neutron the extra rest mass.
Some photons, neutrinos, and a positron is also given off as the total energy of the neutron rejects the excess energy from the original collision. After all, quantum particles really love being in their ground states.
oof the quantum jokes. Now to figure out where they're going
Can you test DOSIMETER SMG2 please? or where can i get that sample ore to test myself?
Antimatter matters
Fascinating video. Thanks. Would love to see the battery change. You mentioned calibration - do you think that will be needed? Perhaps you can work that out too? Would be interesting.
Very informative. That 701 has nice clever features built in. Especially that discriminator system.
Yep, I haven't tested the functions of the 701 much yet, but it sure seems to work well as the video hopefully shows. It even has alpha, beta and gamma modes that I haven't had the time to test yet. Thanks for watching!
Where can i buy the black radiascan701a?
Interesting video, thanks for that... On my parent homes, there is old Tilley lamp parts. I suspect the wick the contains Thorium dioxide. Have you measured these items, how much radiation ? Also I have one older wrist watch that is slightly radioactive, I quess the paint material used on the minute / hour pointers could be responsible (radiation was measured for a long time ago, I dit not found the results anymore)
I love you dr. Brainiac
How do you measure the general background radiation? Which mode?
Can you perhaps power the Gamna Scout through the internal USB port if you plug it into a phone charger?
I love looking for radioactive rocks in the woods and I was thinking about getting gamma scout but now I think I'll go with radiascan considering it outperform gamma scout and it's also cheaper!
I learn so much Chemistry from you than in school
Thnx xd
Can't you apply the inverse square law or a function to use the detector that maxxed out at a greater distance and arrive at an approximate reading of the sample's radiation?
Have you done anything with the biohazard sign yet? If you have which video was it🤔
When the equipment screams in morse, you know your boned
you're*
And no, you are not boned. But you have to pay attention.
I like the way you show atoms with floressing materials.
Owao just amazing
Was that a firewire connection inside the geiger device? What's it for???
Quality > quantity I love your videos and your attention to detail mate.
That pitchblende rock is scary to me in a way I can't quantify. Thinking of all the potential accidents associated with keeping that in your home.
It's really not that big of a deal if you don't sleep on it. If it was, he wouldn't be allowed to have it in the first place.
Marie Sklodowska Curie was so hardcore.💙
