Attention!!!! In this video I am searching for cheap and sensitive Geiger counters, so that people can detect even the smallest level of radiation. This is important if you want to check your food for if they have radioactive particles on the surface. The bigger GM Müller tubes are perfect for this purpose. I can definetly recommend the orange Geiger counter NR-750 by Pudibei.

The smaller GM tubes do not detect low level radiation very well. But they can detect really high radiation before maxing out. This can be important for when you are really really close to ground zero of an a-bomb. If you also want to detect really high level radiation I recommend more expensive Geiger counters that preferably have 2 Geiger Müller tubes at the inside (one small and one big)
I work with radioactive isotopes and we use survey meter's
Thanks for the review. Just found a 750 on Amazon in the US FOR 60$. Was about the 5th selection down on the search list.
@@bonedoc4556 nice 😃
Some of those are not real time readings. The white one has a 30sec refresh. If I remember
@@Mr_Wicked it is super slow. it sucks compared to the others.
Hopefully NONE of the Geiger counters will be reading any REAL high levels of radiation in the future.
God willing and
God bless and protect us all!
Hopefully. There can be things liks naturally occurring radon gas emissions that can buildup in basements or structures. These things can have more uses that in nuclear plants or wars.
@@theoldguy9329 how so?
@@joriskylie6857 I am sorry. Was the question about radioactive radon gas which is released by a number of naturally occurring minerals (actually not uncommon here in Canada). Mone tailings and erosion may also spread radioactive minerals. Or maybe things like the tailings from those old factories that put fluorescent dials on clocks watches, compasses, airplane instrument dials, submarine equipment, etc..
@@DaedalusHelios also wrap in tin foil before putting in cage
I'm really enjoying your posts, its nice to see someone with common sense putting out some really intelligent posts. Hopefully we don't need it but I am definitely interested in picking one up. I'm a 26 year military veteran and used to teach this stuff :)
Seems you don't know much from 26 years of brainwash. You and her is dangerous people. Common sense seems what you lack there.
@@hhbeck-ziegler9333 brain wash in what way :) Im talking from experience of what I have seen, not what I was taught or told

This is the only prepper review of Geiger counters I've ever seen. Thank you Lilly !
Thanks. I bought one on your advice and am delighted. The build quality is far superior to other more expensive devices. Does the job well. Thanks xxx
Thank you soo much for the review! I went and got the NR-750 on Ebay and made offer for $40 US + they accepted! great review + comparison, thanks!
Great deal!!
The cheapest GQ Electronics model (GMC-300E-Plus) is $128 USD. They have good support and easy to read screens. (I have their GMC-600+)
Just a quick additional upcheck 👍for the GQ 300 series counters. Currently Amazon has great deals going on the GMC300S and GMC320S versions. My 300S was only about $50 with a coupon, and the even more capable 320S is currently discounted with a $15 coupon to under $60. Both the 300S and 320S have the larger full sized more sensitive Geiger tube mentioned in the video, a large backlit sunlight readable LCD, a standard easily user replaceable 14500 lithium battery, and full-function onboard internal firmware which allows both USB PC logging and precision CPM/uSv instrument calibration (unlike the highly over-rated, over-priced POS 'Gamma-Scout'). With the slightly more expensive 320S, you get a few extras like automatic cell phone style display flipping, an internal electronic thermometer, plus a larger 1M internal logging memory - but even the inexpensive GMC300S model is enormously more sophisticated than most of the other tinker-toy counters in this video. So far as the testing in the video goes, Gieger tubes show widely varying sensitivity depending on the energy spectrum of the radioactive source, so testing counters against random radioactive rocks (especially up close where the levels are changing rapidly with distance), is NOT going to give accurate results. I have checked the accuracy of my new GMC 300S, and my new RadiaCode 103 (much more expensive, but also highly recommended), against a calibrated Cs137 check source at a calibrated distance, and found both were within 10% of the calculated theoretical gamma flux, which is surprisingly good accuracy for consumer grade devices.
@@bwilder2324 GQ also had good support. I had a bad LED in my GMC-600+ and they let me just swap it out with a replacement they sent, rather than the hassle of sending it in for warranty repair (and the risk of damage in shipping). Confirmed this wouldn't void the warranty. They have a good forum on their site where you can discuss issues and suggest improvements.
Personally, I would get an inspector. they’re very sensitive but they only give accurate doses for Cs137
I decided to purchase a Geiger counter a few months ago but had a limited budget. You will be pleased to know that I finally decided on the Purible orange one and it has been sitting with the first grab equipment since. Such a relief that you tested it. Thank you so much!
Most Chinese units run a glass Geiger tube that is also sensitive to certain wavelengths of UV. If you buy such a unit, make sure the tube is isolated from ambient light. Black heatshrink tubing works a treat and is easy to apply, as the tubes usually tend to be removable from their sockets. Good to see the newer units in this video came with shielding, I guess some mfrs caught onto the issue finally.
Also if you're going into Gamma Scout price range, the SE International Monitor 200 is a worthy contender. Made in America!
Hello, indeed it depends on tube. J305 is UV sensitive (could overestimate by x20 counting) whereas J321 isn't at all ;)
I grabbed a cheap 'non-brand' Chinese unit a while back to see how it would fare against my GS3 (at 1/10 of the cost) and was pleasantly surprised in terms of (reasonable) accuracy and features.
That said, the lack of an audio pulse feature is peculiar (it'd be so easy to include) and of course, no alpha detection.
Anyway, re UV sensitivity and overestimation, I've found the opposite to be the case with this thing (It's a GC01) which reads slightly (and consistently) lower that the GS3 when tested with a thorium mantle, possibly due in part to the thick, black rubber sections of the casing and a J321 (I haven't opened it up and the Chinese translated manual is a little spec vague but I believe it's the 321 in there).
Interestingly, to get an accurate reading, the unit needs to be positioned so that the rear is facing the test source. Pointing it towards a source (as one would with the GS3) only registers a slight elevation from background levels. This makes quite a difference too; 0.7ųSv shoots up to around 2ųSv. It is however, rather awkward to hold it in such a way that allows for an optimal reading.
Also, as I mentioned, it does generally read slightly lower than my go to unit and I'm wondering, provided that the rear casing has sufficient clearance from the tube / board and that the tube is indeed a J321, would drilling a series of small perforations through the back seem like a reasonable way of increasing the beta sensitivity to match that of the GS3 or would the difference be negligible?
The book nuclear war survival skills shows you how to make one from a small can and things around you home. If you do not have much money build one or buy a dosimiter.
Thank you, good tip.
There used to be a complete kit. To make one.
Lily if you are not okay with me posting the link. Let me know.
Thanks Lilly.
@@bobfall RUclips automatically deletes almost every link you post, so it's probably not going to work.
Interesting reviews but realistically, if it reaches a point you need a geiger counter to support your survival, you have much bigger things to worry about than radiation.
remember that jet stream will bring all those nuke particles around the world, now you can tell if you have any and how much!
Thank you, Lilly, for buying and testing all these geiger counters. Excellent fair review and recommendation. I trust you, and I value your opinion very much. Thanks again!
Boy thanks Lilly I just ordered the NR 750 after waisting over $60 on a different model that wouldn't even stay on. I tried everything. Keep up the great work ❤️
@mikemorris5944 I read that you can enable particle detection sound with NR-750 but other users only reported this feature with their NR-950.
Here are some instructions from another user:
"Go into alarm mode, then select the pictogram of three little speakers. This will register a beep every time the tube records an ionization event."
The NR-950 has features I don't need and is more expensive, so it would be great to know if NR-750 has this before I buy it.
@@sfdghjk1017 thank you as soon as I receive our NR-750 I'll test that and get back to this thread post. 🤔
Great video , love the disassembly part, so I could see the used tubes. Just bought the orange one, almost bought the least good one. Thanks for the video, stay healthy
Thanks Lilly, just bought the orange one. I was wondering for months what I should buy and kept on looking at the choices on Amazon. You rock! Beste Grüsse aus der Schweiz
I built one in a kit form 20 years ago and they still work today. Thanks for checking these out.
Lilly a very interesting video! I am in my late sixties and when I was a teenager we were fascinated by the old watches with the radium dial. Little did we know they were radioactive back then. Thanks for the content Lilly!
I used to wear one. We didn't know any better. But I don't think I've suffered any ill effects from it.
Omg this is exactly why I wanted to a Geiger counter for cheap because I wanted to test my grandfather’s old watch faces for fun and also I remember using a good gouged counter of my fathers when I was a kid to test things around my house 😂
Timely review as I have been searching for a Geiger counter. Well done!
I remember watching a program where tourist took a tour in a town in Japan that had to evacuate due to radiation the tourist had the cheaper gigor counters. Thank you for helping us out to know what to get
After watching Canadian preppers post today I just came back to this video of yours and as a result of watching your review here have placed an order for the NR-750 Radiation Monitor. Many thanks for all that you do keeping us informed, TL in UK
Hi, Lily! I bought the GQ GMC-300E Plus from Amazon a few years ago, and it works very well.
I have one as well, and it works well. Matches my Radex GC (Russian) exactly, and is sturdier than the Radex. I don’t buy on Amazon, too many problems, I buy from EBay or the manufacturer, and have been very happy without Amazon.
Talk about a detailed analysis! Outstanding and well-done Lilly!
Thank you for this information Lilly. Stay safe
Thank you so much for this, Lilly!
You did a great job in thei video and part 2. Everyone needs to have one and you made it possible to have the right one at low cost. Thank you.
Good job reviewing. Thank you for being so timely.
I wish I saw this video a few months ago. I bought the "wrong" geiger counter. A very insightful and appreciated post, Lilly!
Thank you for the great test and review. So glad I came to your channel to see some non biased reviews. I’m planning on getting one you said was good tomorrow.
Thank you , this is a great comparison and you did the research for us .
Your amazing Lilly. Thank you for your hard work doing this!
Hi Lilly, this is BigJoe from L.A., once again, thank you for the awsome insight and for caring about the survival community🙂.
Everyone here pissing themselves over nuclear war and I'm just here trying to survive antique stores. You wouldn't believe what kind of hot items you can find.
That’s exactly what brought me here. I just want a small counter so I can check the authenticity of all the uranium glass sitting at my local antiques outlet lol.
@@joshfrommilan6130 im here just to be sure that no scrapyard near me gets something extra spicy.
@@hardnachopuppy I’m reminded of an episode of House where a kid ends up severely irradiated by a scrap souvenir his Dad found in the family scrapyard. Now I’m sad.
Thank you for teaching me and showing us how these work
Thanks for doing the work Lilly. I just ordered the NR-750.
Thanks for your review/analysis and the Ebay link. Couldn't find it on Amazon but did on Ebay, so thank you, thank you, thank you. You're great!
Very useful. I had been wondering if any cheap Geiger counters would be any good. Originally for fun but now not so much! Stay safe and excellent idea about the faraday cage that I hadn’t considered ❤
Thank you for doing this test! I live in Sweden, and have recently also begun to consider buying a geiger counter. Crazy times, and you better be prepared.
Thank you Lilly, you are awesome, everyone else is just a waste of time but you get to the facts we need.
Thank you SO MUCH Lilly for this informative video. I pray to God we never need them but you've shown us the good from the bad. 🤗
Thank you for your hard work Lilly.
Thank you for this. I was overwhelmed with what I should get.
Thanks. Great info for your audience. I bought a bit more expensive one and hope to be able to test it some day.
The emission of radiation at low levels is relatively random in timing -- there are random number generators based on a radioactive sample decaying. What you get for a reading for radioactivity is an average over some time (likely seconds) which you may be able to adjust. That time may be the difference between fast and slow response. It is certainly not the reason for difference in levels.
As a dossimeter reading the total radiation you have been exposed too over hours you might get longer sampling times.
The sensitivity is dependent on the Geiger Muller tube having the correct voltage applied. Other than that it is the tube's characteristics ( standard calibration chart for the number ) and the circuit is just counting pulses over sample periods. Longer, and therefore slower, samples should be more accurate. The other refinements are just selective filters for the tube. Dead units really show a lack of quality control.
I kind of like a kit for basic counters because they have schematics, alignment and calibration procedures, and as the circuit is quite simple are easy to repair.
That insensitive unit probably just needs the voltage to the tube adjusted but without service information it is useless.
Thank you so much!! I just ordered the N-750 :)
Dont forget that the BR-6 tube is from one of the top corners to the opposite corner at the bottom, you can see the GeigerMuller tube through the grid in the back.. The window on the gamma scout is at the top of the unit. I have the similar to the BR-6, also the GC GMC-320 Plus, The radiation Network GeigerGraph (from Mineralab) has many many counters on line so you can see radiation counts all over the world. I have an actual Radiation sample/calibration disk from the early 1950's. Ah the black on has the mini GM Tube, by the way some of the older Counters have a metal tube, mostly the Russian ones. Great video, you really show how things work with the Geiger Counters.
And the allowable dose limit for the civilian population is 5 msv. For one year. Safe boundaries.
Thanks ! I bought the NR-850 for $65 on eBay. I appreciate your review.
Thank you for the recommendation. Been looking at these and now I know 100% which one to purchase.
Just bougt a "Better Geigor" off Amazon an awesome good quality geigor counter for 150 dollars, a High performance. Low cost. Simple to use. Rugged. Made in USA, A radiation dosimeter measures dose using a scintillator instead of a Geiger tube. Im very happing with it so far
I'm at their site and considering buying one. How long have you had it and have you tested it? Thanks.
@@MrFirstone23 I just got it yesterday and only turned it on to make sure it works. I have been researching these less expensive ones. If I was going to pay 500 dollars I would buy a an older 1960s/70s Victoreen survey meter or geigor counter but they are hard to find and expensive. So I reviewed the Better Geigor watched a couple videos and choose to go for this one. Im goung to order the source its about 40 dollars. Wish i could tell you more but do a youtube search on it there are a couple videos on it reviews can be seen on the web page. I like the fact it reads in MR/Hour and sieverts here in USA I worked most my life in a Nuke plant and used MR/hour
Useful information. Don't forget to keep it in a faraday cage with fresh batteries. An empty metal paint tin is a good EMP shield. It's worth buying potassium iodide tablets too.
everyone says buy iodide tablets, but fails to realize that IF there is need for those tabs, background radiation will be high enough to cause permanent damage to other tissue in body, not just thyroid. IMHO best way is to get good geiger counter/ dosimeter and RUN AS FAST AS YOU CAN if they start chirping.
@@ApocGuy I can't speak from experience because I've never myself personally endured a radiological event, but the use case I am anticipating is the detonation of a device far away but the dispersal of radioactive fall out in my vicinity. In that event I would stay indoors with my windows and doors taped up, and take the iodide tablets. I would wait out the fallout for maybe a month before going outside. I would use the Geiger counter to check to see when it is safe. I would also use it to check water and food. I would probably wear an N95 mask as well to minimize inhalation.
I'm not planning for a massive local event, just to minimize the health impact of fallout from an event elsewhere. Under those circumstances ingestion and inhalation is the enemy. I don't have unrealistic expectations, I just want to maximize my chances of avoiding long term health problems.
Storing enough water and food for a month is achievable. My biggest concern is having access to uncontaminated water. Water from a loft tank or aquarium can be drunk if you get caught short. Pet food and pets can also be eaten. Just my little joke.
Excellent reviews Lilly! Thank you. Cheers.
Thank you so much - I just bought the one you recommended for testing my Czech pitchblende specimens!
Great Topic Lilly Thanks!
WOW, what a great scientific demo/explanation Lilly! I can tell from your procedures and methods of data collection that you are a true scientist and probably have a BS degree in Physics if not a Phd. I am very impressed with someone who has her own Faraday cage! As we use these wonderful scientific instruments we must always give praise to the great German scientist Hans Geiger. Was Muller his grad student? Are the Sievert units of measurement also named after a great German scientist? BTW your English is excellent.
The reason why the BR-6 wasn't testing very accurately was because the tiny holes on the back of the dosimeter block most of the particles going into the sensor. Most people drill holes in theirs and cut the heat shrink on the tube to make them more accurate.
Thank you Lilly! You are the best!
I hope, we never need one. ✌🏻
Great review! Thank you so much!❤
Thanks Lilly, Hopefully they will not be used. Enjoy your channel, keep prepping, watching from Canada.
Thanks Lily. A really nice overview.
Excellent review! Thanks for sharing your time, testing, and technical skills!
Excellent video. Thanks Lilly
Love your content Lilly! Thank you!
You answered my question thanks Lilly bless you!
Danke fuer dieses video Lilly. Sehr erleichternd 👍😁
Thank u Lilli for this video. Ordered mine on ur recommendation.
Thank You I was looking at those very counters just the other day.
Good idea to have two detectors with the one you plan to have with you when away from home being less than $100. If you lose your get home pack in the chaos of post detonation, it is not much of a total loss because you will still have your more feature packed Gamma Scout safely at home so you can test your food and anything outside the house before bringing it inside.
Great comparison content, Lily.
Thank you for all that you do!!! ❤️
Cheers Lilly for this very informative video 😁
Thank you!!
Ahhh thank you again Lilly for getting what needs to be done, done!! =)
Good research Lilly. Great Job !👍👍👍👍 Stay safe and warm ....Michigan, USA
Thank you so much! Love your channel.
Thank you for that great review! I currently cannot afford a gamma scout, and amid so many relatively sketchy ones on amazon, the NR-750 is a great and affordable alternative.
The China glass 4011 GM tube is a lesser expensive version of the Russian made SBM-20 and claims to be more sensitive however being clear glass it suffers from light sensitivity unlike the metal SBM-20 and that's that's why one had a black cover.
I watched both parts and picked up the NR-850. Very informative and useful information
Thanks for the selection! Thumbs up.
Thanks for the honest and thorough reviéw. It's not a product that should have fraudulent or useless, deceptive items foisted onto public. Maybe they will be the "free ones" handed out to public to "reassure them there's no danger here" Hoping those with good tech will help others if the awful events happen.
Thankyou for reviewing these, I have now ordered a pudibei 750.
Thank you for the Review... very interesting
Thank you for the information. We will definitely be ordering one soon
Thank You, Lilly!
Very awesome video. Thank you for testing the different equipment.
Thanks Lilly . Excellent review
Thanks for the review, ordered one :)
Thanks for the info. I think we all need it now more than ever.
Good morning from Syracuse NY USA my friend
Great! I’ve been curious for a few years on this very topic - especially considering your pinned comment. A perfect use scenario
The best geiger counter review on YT. Many thanks!
Great video, timely, informative and real.
Thank you and ❤ from 🇨🇦
Excellent! Well done and extremely timely
Thank you Lilly,this is a big help.P.S. Love all of your video!
Hello from the uk thankyou for another great informative video ive found the recommended counter about 60 pounds on amazon love your work xx
The review was fine to determine which counter was the most sensitive; however, after a nuclear strike, the levels of radiation will saturate (overload) these devices for the first 2 or 3 weeks after which the level of radiation will be much weaker and then within the range of these devices. I like the GQ GMC-500Plus Geiger Counter on Amazon which can measure up to 42500uSv/h or .042 milli Sieverts.
Sure, if you have the money you can always invest in a better geiger counter. But most people dont have so much money, especially after what is going on with the world economy. Also in my opinion these sensitive geiger counters are good enough to let people know what is going on.
@@SurvivalLilly I did not mean to offend you Lilly, I love your post and channel. The one I mentioned has come down in the last year and I just saw it on Amazon for $200 dollars. I also bought the white one that you reviewed and it worked well; but I found some of the test sources I have would max out the reading. I did not mean to put down the purchases you made, they are good for what they were designed for. I love your channel and hope and pray you will not have to go through a nuclear crisis.
After removing the rubber tube the white one still sucked LOL I'm glad you retested it. Thanks Lilly :)
When they melt in your hand it’s all over I guess. Informative video. Thanks. Demonstrates distance from sources is very important as well.
Great job Lilly!
Informative as always . Thank you
Sincerely appreciate you for doing this!😮
