- I bought 5 cheap Geiger Counters on Aliexpress (all below 35 US Dollars) and tested them against each other (and against my Radiacode 102 as a Reference Detector). Some of them are actually really cool! and some others are utterly horrible ;) Join me if you wanna find out which are my favorites!
PS: I am not planning to become a Review Channel, but once in a while, these are Fun! :)
I used my Radiacode 102 as a Reference Instrument, tested Geiger Counters are the following:

I made a kind of follow up Video for everyone whos interested in a deeper look ;) If you wanna see how i put a vintage SBT-11a Tube into a BR-6, take a look here! :D ruclips.net/video/X6RCCVnnNjU/видео.html
Have you seen the new Gmc 800 ?
You think thats a devent counter?
This was great, thank you! "Does it click?" is totally important! If I have a Geiger counter, I want the drama of knowing how scary something is!
I love my Radiacode 101. I just pre-ordered the Radiocode 103G, it should arrive soon.
Great extensive test thanks, I've just purchased the br-6 before I watched your video so I'm glad it won the test 😂
Thanks was looking for this video last year, and when searching for it again your video came up. Thanks, alot for the in depth tests I was already looking at the BR-6 and finally decided to buy one.
This video is very exciting; I hope to see more radiation measurement instruments.
I bought BR-6 without reading reviews and I'm quite content with it. I liked how it doesn't have any gimmick. Just a board with the tube, a buzzer that can be turned off, a display and a box. Nice spacing between the grates and the tube, nothing wobbles, nothing is too covered. It also works on two AA batteries, which is nice as I greatly dislike built-in lithium cells.
I'm gonna use it to hunt uranium glass in thrift shops and possibly some minerals from waste piles. I think it will do well for that purpose as it's quite fast reading and sensitive. Thanks for confirming my intuition for the product.
Fantasitc video! I bought an HFS-P3 last night along with the GC-01 GM's. Good to see I didn't waste my money on the HFS-P3. I got them from AliExpress :D
I'm suspect of the right-to-left checkmark technique. I've never seen this before.
probably want to compare the radiacode directly to the GMC series since those are the most popular brands that people would buy. Ive never heard of this chinese stuff.
Hello. What about the Pudibei NR 750 that Lily told. Is it better than BR-6?
i dont now the nr750, also i didnt see lils video on it ;) but looking it up on google it looks pretty similar :)
Cool video, i have the last one at home :D
I really want to like the sharpie marker sized one, it's too bad it doesn't perform. Would it be possible to modify it with a Russian tube (are the voltages appropriate out of the box?) Also, is there any mod that can make them click, like a simple speaker soldered on the right place?
yeah it would be really cool to modify the HFS-P3 :) I only have one soviet tube that would fit, i did a quick test but it kinda performs similar.. im not aware of any good tubes in this size unfortunately (but im shure theres one out there!;) the voltage should be okay for most standardish 400v tubes i would guess, even if its abit on the lower side (i made a voltage sheet somewhere in my other video;) for youre click idea.. i had an idea for that but never tryed if it works ;) if youre good at soldering, maybe try to connect the positive of the LED (it flashes for every click) with the inbuilt speaker ;) cooould work! or use the LED positive to drive a tiny extra piezo or something.. i think LED positive is youre best chance for the click ;)
The BR-6 probably picked up more Beta than the others because of the open grill on the back. Beta is easily blocked even by a thin sheet of plastic.
I'm new to the whole thing, but I heard that radiocode 102 doesn't pick up the alpha and most of the beta radiations (like the 101 before it)
Is that true? 🤔
..im pretty shure none of the radiacodes pick up any alpha, maybe they do get some hard beta. but in general i would say dont worry too much about alphas and betas if youre a "beginner". Gamma is the bigger topic anyway ;) There is the Measall KC 761 if you want a full spectrum device, but im pretty shure is not very "beginner" friendly ;) PS: Check out the Channel "Studio 326", he has great videos on all that stuff! :D
I’m pretty upset that I got the white plastic one, I didn’t know it was a fake not real Geiger counter! Wish we could still return it :(
Great video, I just got the HPF-P3 in the mail and didn't knew it didn't have the audio.. ordered a BR-6.
What are you looking to add to yours? I haven't understood.
Thanks for the great video
good choices! i really like both these detectors :) the HPF-P3 just to have in my backpack at all times, and the BR-6 for actual sensitive identification of low level sources like the Potassium in the Plant Ashes. What i already did is order 2 more BR-6es ;) One as is, one as experiment platform, and the last one i swapped the GM tube for a soviet SBT-11a (alpha beta gamma) Mica Window Tube. It works really great with the SBT-11a, its extremely sensitive with this tube! great for low level sources ;) I will post a video soon talking about the modifications ;)
@@BremsstrahlungChannel really looking forward for this video. Is it as simple as swapping it or support component on the PCB are required as well?
Its pretty simple, you dont have to tamper with the PCB. You only have to add a Resistor to certain GM tubes for them to work properly ;) @@DiaLFonZo
@@BremsstrahlungChannel I'm already looking around for a tube but can't find anything 😔
Yeah the market got quite abit more difficult in recent years.. i always went to sovtube.com a few years ago, but theyre almost sold out as it seems. there are some offers for soviet tubes on ebay, mostly from ukraine. prices went up a bit but you still should get sbm-20 for 30 bucks or sbt-11a for like 50 bucks max i think.. i dont really have experience with american tubes, but i think you can buy pancake style tubes online as well, may cost abit more ;) or the chinese tubes from aliexpress or similar sites! m4011 is a geat beta gama xray tube, and the j305 seems to be a good copy of that tube.. but so far i didnt see any chinese alpha capable tubes..@@DiaLFonZo
I have a question. Does the second cheapest one measure a beta type radiaton ?
good question! and after some further tests, i guess my answer is "maybe a little" ;) i dont have a "clean" beta source, but i did some further tests with the small J613 Tube thats in that detector, and as with most small tubes, the count rate is just very low. What i am pretty confident about however is that the BR-6 can detect Beta. BR-6 has the J305 Tube, wich seems to be the best of the 3 Chinese Tubes. I will post a new Video soon where i go into these details abit, and modify some Counters ;)
@@BremsstrahlungChannel Oh thank you for the answer, I've got at home few rad.a. things and I want to buy a dosimeter that is not so expensive but I want it to measure not just Gama waves. Actually I want to measure how much is my tritium chain harmfull because tritium is the most pure beta emitter
oh cool were talking Tritium! :D ive got some experience.. i have a small tritium keychain as a test source as well ;) and its my most difficult test source, even the plant ash is way more radioactive ;) i tested BR-6 with sbt-11a on the tritium and it can just barely pick it up. the only detector i have that can clearly detect the tritium is my Radiacode 102, but also with that, the count rate doesnt even really go up, but you can see the bremsstrahlung xrays on the spectrometer at about 5 kev. the thing with tritium vials is that they also emit a very small amount of x rays (because of bremsstrahlung interactions of the beta particles and the plastic/glass shield), so its also not really a "clean" beta source in practice. if you want my opinion, i would not wear it as jewelery on youre body, because it will give you a small dose of radiation over time (the x rays are not great over time eighter;). but if you have it as a decoration item somewhere in youre place, with a small distance to you, id say that should be harmless. ill do some of these tests in the upcoming video for shure ;) @@wufan.cz.
@@BremsstrahlungChannelIs the radiacode better than all the others in this video? I'm looking for one to detect radiation from nuclear fallouts/events as well as from reactor meltdowns. Need something applicable for that
yeass thnxx!
👍
I got an SBT-11a to install in my GMC-300+ but im not sure i have it working correctly. The background cpm went from ~20 with the M4011 to around 200-500 with the SBT11a but checking against some spicy pottery doesn't seem to change much.
ETA: just tested it again, background was 160-200 cpm on the SBT-11a modified GMC-300 and around 16k cpm combined alpha/beta/gamma on a fiesta plate. The only other unit i have to compare with is a CDV-718 and it is reporting ~3mR/h combined beta and gamma for the same plate.
I need a proper procedure for calibrating this franken-detector.
..if i remember correctly, theres a thing with Resistors on certain Tubes ;) I think i had a 1 mega ohm resistor between the + terminal on my 320 and the + connection of the sbt-11a in serial. Its really been a while and i forgot alot of details about my modification project, but back then i found alot of good forums (in english and german) that explained the stuff really well, its just a bit of googling i guess ;) PS: the 200cpm background is for shure too much, this should settle down to around 30-40cpm with the resistor installed (both tubes have relatively similar cpm values). i think they tend to freak out on the lower end of the cpm spectrum if the resistor is not there. good luck mate! btw if i find the relevant article, ill post it here ;)
..just did a quick google search ;) so its 10 mega ohm, not one. this here seem very decent, he talks about bypassing the 3Mohm on the board and connecting the 10 Mohm resistor there, but in my amateurish knowledge i would say cleanest solution is to just add a 7 Mohm directly at the clip.. it also could be that i used a 5Mohm (plus the 3Mohm internal is 8, wich is close enough to 10 i guess :) www.reddit.com/r/Radioactive_Rocks/comments/15ivhv4/finished_gmc320_sbt11a_probe_modification/
@@BremsstrahlungChannel Okay, that's what I'm missing. Thank you so much!
I'm using a 2M resistor@@Yaivenov
im going on br6
Is FSG-001 reliable?
i dont own one of those, maybe try to find some forums on that model, im shure there are some people who have experience with it ;)
@@BremsstrahlungChannel Neither SGP-001?
@@RynaxAlien nope, i guess you have to test them yourself ;)
Nun, da hätte man sich noch ein paar mehr Testkriterien einfallen lassen können, z.B. wie lange hält das Gerät mit einer Akkuladung oder einem Batteriesatz durch? Wie ist die Ablesbarkeit der Displays im Dunklen oder im hellen Licht? Ticker haben die Chinadinger ja sowieso seltenst.
Zu Deiner Frage am Ende habe ich eine Antwort: In dem Test fehlte leider der seeehr weitverbreitete und ebenfalls billige FS2011, den ich bisher immer komplett verachtet habe. Aber: Für diesen gibt es eine alternative Firmware namens "RadPro" die ein wirklich benutzbares Gerät aus dem Billigding macht! Und obwohl das Gerät selbst keine Schnittstelle zum Auslesen hat, beherrscht das dann Datalogging. Man kann die Schnittstelle zum Auslesen der Daten aber nachrüsten, der Prozessor hat UART-Ein- und Ausgang, über den das läuft. Selbige Firmware gibt es für den BOSEAN FS-600 (hier im Beta-Stadium) dieser HAT sogar schon die USB-C-Schnittstelle, man braucht nichts umbauen. Der FS-600 hat btw einen schönen Formfaktor, der ist schön klein. Auch den in den Originalfirmwaren nicht eingebauten, aber wichtigen Ticker rüstet die Firmware nach. Sogar mit der Option, die Displayhintergrundbeleuchtung als optischen Ticker zu verwenden - sehr clever! Für Leute wie Dich, die andere Zählrohre adaptieren, ist dann auch der Kalibrierfaktor veränderbar, so dass die Dosisleistungsangabe wieder stimmt. :D
Danke sehr für die tipps! Und auch für die Kritik :) ..ich hab mir dass mit der Batterielaufzeit noch überlegt, hab mich aber der Videolänge wegen dagegen entschieden, wollte es irgendwie möglichst unter ner Stunde halten ;) Muss mir die 2 Geräte die du vorgeschlagen hast umbedingt mal näher anschauen, würde gerne mal probieren ob ichs hinkriege mit der alternativen Firmware. Mein GMC-320 ist glücklicherweise wieder zum leben erwacht, daher hab ich aktuell wieder nen logging fähigen Counter.. hab noch ein Wetterballon Projekt am start irgendwann evtl diesen Sommer, da würd ich gerne nen günstigen mitschicken und nicht meinen geliebten GMC-320 riskieren ;)
@@BremsstrahlungChannelAhaaa, sehr interessant! Mit Ballons kenn ich mich auch ein wenig aus - als Radiosondenjäger und vor Jahren auch einige Schüler-Ballonmissionen begleitet. Noch ohne GSM-Tracker und Internet, alles nur Amateurfunk und offline-Karten. Es gibt ja sogar Vaisala-Wettersonden mit Zählrohren - die sind aber selten, ich hab leider keine. Und wenn ich eine hätte, würde ich die auch nicht wieder auf die Reise schicken.
Aber warum willst Du loggen? Das erfordert ja immer das wiederfinden der Nutzlast - das ist nicht immer gegeben. In Jena hat einer (DO1VHT) eine Geigerzähler-Nutzlast für Wettersonden konstruiert und lässt die über die Jahre immer wieder in das Regener-Pfotzer-Maximum steigen. Hab selbst mal eine seiner Nutzlasten geborgen und zurückgebracht. Man sieht wohl, dass sich dessen Höhe langsam ändert.
Aber natürlich kann man auch mal 35 EUR für einen FS2011 ausgeben und den einfach mit ranbinden, wenn der Ballon groß genug ist. Das Umflashen ist wirklich gar kein Problem, auf GITHUB ist das alles erklärt. Und der materielle Verlust ist verschmerzbar, wenn die Nutzlast verloren geht - schade ist es dann nur um die Daten.
Auf meiner Kanalseite findest Du auch einen Link, wo man Strahlungsmesstechnik näher diskutieren kann, falls Du da nicht schon angemeldet bist.
Wow sehr spannend! Das war sicher ein abenteuer ohne gps und smartphone karten :) Für mich ist der Ballon einfach ein Projekt dass ich einmal im Leben mal gemacht haben will ;) Konnte vor paar jahren 2 US Army Ballons kaufen auf ebay, hab eigentlich alles beisammen von der Sonde mit Arduino und ein paar sensoren bis zum Fallschirm, hatte einfach noch keine Zeit das durchzuziehen. Natürlich geht es mir auch um die schönen Bilder bzw Videos, denke über den schweizer Alpen gibt das sicher wunderschöne aufnahmen :) Auch ist die Gesetzeslage in der Schweiz sehr "entspannt", braucht nicht mal ne bewilligung dafür hier ;) Naja und ein Geigerzähler gehört für mich da einfach dazu :) Schlicht um die Höhenstrahlung zu zeigen. Mal schauen ob ich das ding dann auch wieder finde, wird sicher ein schönes abenteuer :) PS: Meinst du mit dem Link das Geigerzählerforum? Natürlich kenne ich eure seite, habe da schon viel gelernt und schätze das forum sehr! Ich bin selbst einfach nicht so der forums schreiber, aber ich muss mir umbedingt mal einen account machen ;) @@dg0mg
@@BremsstrahlungChannel Okay, dann wünsche ich Dir schonmal viel Erfolg! Ich weiß nicht, wie das Grundkonzept Deiner Nutzlast mit Arduino aussehen soll: Live-Aussendung der Position (z.B. auf 433 MHz) oder nur mitfliegende Tracker die nach der Landung per SMS o.ä. die Position melden?
Bei beiden Varianten gibts Probleme, in die man unerwartet laufen kann: Bei Live-Aussendung ist zu beachten, dass die billigen Maker-GPS-Module über 10.000 Meter Höhe ihren Dienst versagen - die liefern dann einfach keine Daten mehr. Das ist unbefriedigend, wenn man mitten in der Flugphase plötzlich keine Position mehr hat - muss man also vorher austesten. Die GSM-Tracker haben ab gewisser Höhe keinen Handyempfang mehr - wenn sie in einer bergigen Gegend (soll CH ja sein :) ) in Tallage landen, haben sie womöglich auch kein Netz. Das hiesse, die Nutzlast ist u.U. verloren. Manche machen zwei Tracker mit SIM-Karten unterschiedlicher Netze rein, aber das artet imho alles aus. Andere Variante ist ein Peilsender, der einige Tage sendet. Wenn das Landegebiet ungefähr bekannt ist, kann man rumfahren und nach dem Signal lauschen.
Empfehlung: Fange langsam an, nicht gleich mit Kamera und großem Ballon. Zur Not auch erstmal mit Kinderballontraube. 10 Ballons mit 30cm Durchmesser heben auch schon eine kleine Nutzlast. Suche Kontakt zu einem Wettersondenjäger. Der hat VAISALA-Wettersonden übrig, die man umflashen kann. Dann senden die auf 433 MHz im ISM-Bereich. Modulation z.B. Funkfernschreiben (RTTY). Zum Dekodieren reicht ein Funkscanner und ein PC mit Soundkarte. Die Software FLDIGI hat die Funktion, die empfangenen Daten auf die Webseite HABHUB einzuspeisen, dann sieht man die Position auch in der Karte.

First
20 Minutes the white one which does not react to your souce is a Fake Geiger counter. Even the tube ist a Fake. Remove the tube and connect a cable between the 2 tube Ports and the counter Starts showing Fake results. I Just have one Here. The Volltage on the tube ist 3.7Volts and the tube ist only a Glass with a wire inside. Complete fake.
Is there any disadvantages to a scintillator like the Radiacode? Thanks very much
Well in general, i would say no :) Radiacode (and Scintillators in general) beats any kind of classical Geiger Mueller Counter in the same price range. The only things Radiacode can not do is measuring Alpha Particles, and with the Betas its a bit sketchy ;) If youre looking for a full spectrum device, maybe this here could be interesting for you: ruclips.net/video/jcWtnV2ACmQ/видео.htmlsi=B4NB7-Ivn5lHk2q3
@@BremsstrahlungChannel Well tbh I was just looking for something to detect radiation contamination in food and whatever other areas that might be useful if the world ends up in a nuclear war. Not sure if alpha particles are commonly part of nuclear war or nuclear reactor fallout.
@@ryaniam22okay cool :) dont worry too much about alphas, most alpha emitters also emmit gamma, so you should be able to detect most radioisotopes with a standard geiger counter. if you just want to get into the "hobby", i would suggest to buy a cheap BR-6 as first Counter. Theres alot of other stuff besides the "nuclear war" scenario that makes sence to own a Geiger Counter, for example you could go find old Uranium Glass or Radium painter clocks in Thriftshops, Flea Markets etc, or check Fertilizer for Potassium, go looking for natural Uranium or Thorium (depends on youre local geology) etc. If you like the Topic, you still can go for a Radiacode later :) I would not suggest a complete beginner to go for a Radiacode, because besides being very user friendly, it does also have its complexity. But Radiacode is amazing to learn more if you already have a basic understanding on how Radioactivity works ;)
Hi Manutek,
I'm interested on measuring cars that might have been subject to radiation from the Fukushima nuclear accident. Would this devise be suitable at detecting if the object was subject to such exposure and might be unhealthily contaminated?
Thanks.

Hello, and thanks for youre comment! Wow this is a serious topic, im happy if i can help out, but beware i am no expert ;) Well, i would say, if you are on a budget, buy the BR-6, or better 2 BR-6es. If you go for this option, make shure the device works properly, build quality is not always guaranteed with these cheap devices. maybe take it to a known hotspot and check if it really detects anything. If you can afford it, buy something from a known Brand, i would suggest GQ Company, i have the GMC-320 for many years already and its a really good device. Or also check out the Radiacode series, they have more options like a spectrometer, if you want to get more into this topic, radiacode is a great way to learn as well :)
The latest aluminium models are now able to measure β rays, as we have opened a window at the location of the Geiger tube so that β rays can easily penetrate into the Geiger tube. Woo woo we're late.🥲
Are you the Manufacturer? thats really cool! Thanks for reaching out ;) In general i like youre Product, the Design is Great! but i think there are some points you could improve ;) The Slits/Window is a great first step! The other main issue i see with this Geiger Counter is the Response Time of the Software. It is pretty slow compared to other Geiger Counters. For example the BR-6 is really fast, you see change in mSv/h immediately. On youre Device, it takes a few Seconds. If this could be faster, that would be great. The other thing is the J613 Tube. its pretty good for a small Tube, but all small Tubes are very limited in Count Rate. If you want to design a future Model, try to design it around the M4011 Tube (best chinese GM Tube on the Market, Beta Gamma Xray capable) or the J305 Tube (good copy of M4011). Just avoid the J321 Tube, this one is really bad.
Hello and thanks for your reply. Because the beta rays cannot penetrate the thick aluminum alloy shell, we have opened the window corresponding to the location of the Geiger tube, so the beta rays can easily penetrate into the Geiger tube, and this problem has been solved. But I want to explain to you another problem, that is, J613 has a significantly lower sampling rate than J321 and 4011 because of the limitation of its volume, and if the algorithm is the same as J321, it cannot achieve the measurement accuracy of J321. So we came up with the idea of another way, which is to find the actual amount of radiation of the measured object by measuring the average of the past minute. Doing so will cause our styles to appear to react significantly slower to rise and fall than other styles. (But this design can bring me a very big benefit, that is, our detector can pass the metrology certification of the Metrology Institute, and we test it in China's official Metrology Institute (Shenzhen Metrology Institute), and the result is: the deviation of the full scale is only about 5%~6%, which is why our products will be closer to your other model in terms of measurement data.) Sometimes that's the case, and if you want to be small and measure accurately, you have to sacrifice reaction speed, which is unavoidable.@@BremsstrahlungChannel
