- Have you ever wondered if radioactivity affects the data on flash memory like the SD cards in your camera? In this video I will test an SD card against some naturally radioactive minerals. They are thousands of times stronger than natural background radiation, but will they erase data on the card? Time to find out!

#Radioactive #SDcard #Yourwaytospace
This will be useful when I bring my SD cards to Chernobyl.
The SD card will survive the elephant foot but you won't.
Chernobyl is not that bad unless u go to some of the real bad areas but there pretty much offlimit unless you bribe considerable amounts
Hmmm
Or when you have to run your phone through the x-ray machine at the airport.
😂😂💀
I participated in a study investigating the vulnerability of different semiconductor circuits against ionizing radiation during my student years. We came to the conclusion that flash memory is pretty much indestructible when it comes to gamma radiation (at least against the intensities we could create). The vulnerability is the flash controller. Gamma radiation can cause current surges within the electronics when they are powered up, frying them. Even with a surge protection circuit it can cause the flash to be erased because of a current surge on the control lines. So you might wanna try again with the card inserted into a powered card reader for example.
The problem is that alpha particles are incredibly bad at penetrating things. They probably didn’t make it through the SD card plastic cover
Agree, alphas won't do much on an SD card. But there is a lot of gamma radiation coming from the samples too. Look up gamma radiation from bismuth-214 for example. But the intensity from natural samples do seem to be to weak. Thanks for watching!
Those 2 Mev gammas are hitting the SD card like a pebble would hit a tank. You'd need Gev gammas to see an effect.
@@brainiac75 *_Brainiac75, Nice name-!!_*
@@brainiac75 better way to see data change after tests isnt just hashes, but also those hex editors that can compare data bit by bit so u know where exactly the data changed.
@Lasagne did u read EVERY WORD of my comment? do u know what "...isnt *just* hashes, but *also* ..." means???
Me: ‘puts sd card somewhere safe’
*Sd card corrupted*
Brainiac75: *Exposes sd card to radiation and works perfectly fine’
The fact that the geiger counter does an SOS morse code is still hilariously terrifying.
Yes, SOS is a call for help, not a warning to get out!
The uranium is sentient
Why would that be terrifying? I bet it's a built-in function
@@mortbobkanciastostopy9038 It's like Geiger counter, whose existence is to just sense radiation and would be expected to be accustomed to normal radiation dosages, too is terrified of the amount it's seeing and is desperately calling for help.
Radiochemist here. A Geiger counter is not a real thing, that would be refering to a specific type of radiation monitor (sometimes called a radiation counter) that uses a Geiger-muller tube as it's method of section. The device in this video wasn't even a radiation monitor as it wasn't measuring counts, it is what is called a dosimeter as it measures radiation dose rate.
These are exactly the kind of experiments I want to see! So happy to have found your channel. I hope to get/find some of my own radioactive samples one day!
Next time, on brainiac: SD card vs dark matter.
Oh yes, I am looking for other ways of testing the card without visibly destroying it ;D Thanks for watching!
SD card vs Anti Matter
I think that is already on going. Nothing seems to happen.
SD card vs. neutrinos.
@@brainiac75 jeg har en Radium kilde fra en DP-63-a der giver omkring 2mSv/h eller der omkring med beta og gamma. Jeg har ikke en geigertæller der kan måle højt nok desværre, så jeg kan ikke være sikker på aktiviteten. Men du må gerne låne den hvis du vil 🙂 Jeg er fra midtjylland. den har det dog med at kontaminere alt den kommer i nærheden af.
Completely unsurprising result. Comparing the amount of radiation to background makes it sound like a lot but it's actually pretty miniscule. The card's shape works to it's advantage too; it's too thin to absorb much beta or gamma radiation when placed right up against a source like that, but the plastic case will be thick enough to shield the internal electronics from alpha particles.
"this is equivalent to over 40 years of background radiation"
over 40 years would do more to the SD Card than the radiation will ever do
exactly my thoughts
Yea but it's about radioactive radiation only, there's of course more than that
In theory, if it was kept under normal indoor conditions, maybe 70F and 50% humidity, it should still be fine even hundreds of years later. The issue would be finding a device in 200 years that would have the ability to accept the physical format.
i think the worst it can happen in 40 years is the pins having corosion
@Ben Smith still, it would be inserted and pulled out tons of times. The gold would probably come off after just a few years.
I'm happy you used the correct form of "data". Many people don't realise that data is the plural, and use awkward words around it.
"next week I enrich the Uranium and see if the SD is resilient to a full Hiroshima equivalent detonation"
You indirectly and unknowingly spoiled the video.
If he wants higher energy radiation he can take it to CERN (though I suspect the scientists there have more important stuff to do).
@@marc-andreservant201 i think they would’ve preferred a sd card over someones head when it comes to putting something in the way of the particle beam.
He lived too.
Lmfao
@Waldel Martell The LHC particle beam consists of protons. Which are probably more damaging that gamma rays at the velocities they use.
Imagine if we just make a suit with lots of SD card and walked to Chernobyl
5:53 You called them beasts right as the counter displayed 666. 🤘
!!!!!
wtf lol
Uh oh....
coincidence?
He's saying their strong in radioactivity lol
Very clear format and visuals, interesting topic. Lovely video!
As soon as I checked my feed and saw this, my eyes lit up. Anything involving radiation or Chernobyl gets my attention. Immediately.
same
same
Me too!!
I assume you’re familiar with the Kreosan channel then
@@Jakefrc yes I watch kreosan!! I only discovered it a couple of months ago, but have binge watched alot of them. I love the mad experiments that they used to do in some of the older videos, also all the Chernobyl exclusion zone ones are good too!
Kong would have killed Gozilla with a SD banana if this guy did this video 5 months ago
Sounds like you need to partner with someone who has a particle accelerator! 😁
Oh yes, or build one myself :D Thanks for watching!
@@brainiac75 heh, I've sent a message before reading this. You wont be needing 1 MeV of a particle accelerator to achieve that effect on an microsd. Check you my message in here.
That would honesty be interesting did you hear about that person that put their head in one by mistake and has brain damage
Harrison Wells intensifies
Behold, the cancer-inator !!
Next: HDD (Hard disk drive) vs Radioactivity
This is awesome. Radiation is extremely interesting to me and I don't mess with it so watching you test this let's me live vicariously through your videos. Thanks for being safe and preaching that importance. I'd like to see more Radiation tests
Don't forget that during the disposal of the extremely radioactive graphite off of the roof of the sector 4 reactor in chernobyl.
they once used a robot to do that.
Guess how long he survived...
1 and a half shitty minutes
I bet you could get NASA to do an experiment to put the SD card on the outside of the ISS for a few months, and see if the most sturdy SD card you could find would survive.
The station isnt very shielded to begin with and the computers on the ISS have been running windows xp for like 15 years now
Irradiation tests aren't done randomly exposed to elements like that. You definitely don't need to go to space. There are much more intense sources. Usually a source like Co-60 is used because it's got a solid gamma decay, and an irradiation experiment can run at several Gy/h for a couple months and get kGys worth of exposure. In those cases you can start seeing the effects on matter.
@@sunryze3318 maybe ? i havent checked you might be wright, i just remember the tell tale green start button of windows xp on the vids ive seen of the iss
@@jeepsblackpowderandlights4305 wow they need to upgrade
It will not survive even a day. Take a look at some of the video footage shot on the ISS. The camera sensors are full of dead/faulty pixels, caused by interstellar radiation. And that's inside the craft.
First time on TH-cam I've seen a sponsor inserted into a video and I thought wow, that's cool!
i am from the Region in Germany where your Pitchblende Sample is from (Hartenstein is right next to my childhood home)
Pitchblende is so radioactive because it contains trace amounts of Radium.
@@kuroyami3471
most definitely!
the unusual high radiation of Pitchblende(compared to Uraniumdioxide)
was what led the Curies to discover the existence of the elements radium and polonium in their research in 1898
Here in the American Midlands (me personally in Chicago), or what is also called the southern / eastern half of the Midwest we have tremendous subterranean radium / uranium mineral deposits. This makes it actually quite dangerous to build houses with basements, and especially to live in basements or houses with underground foundations that have poor circulation and known ingress of radon and radium. Almost every house in my area has to regularly be checked for acceptable levels (almost none are free of radon incursion), and if you ever visit Chicago, be sure to look around at the houses for radon filtration (basically house air pumps), they typically have a radiation warning symbol on them and hang off the sides of homes as they vent to atmosphere (virtually all you can do is dilute the radiation). I remember reading somewhere that the reasons that such deposits are so close to the surface and so dangerous is that they were exposed by glacial till and removal of many layers of the surface during the last ice age.
I'm not sure if this is common elsewhere, but it's definitely interesting, and somewhat concerning as I rent a garden apartment (a basement) myself.
@@kuroyami3471 my hometown also has a 30% chance radon levels in the basement are over 300bq/m2
there is a famous hot spring nearby whose light radiation caused by the radon content is considered healthy for all kinds of skin diseases.
pitchblende however is a different story - longer exposure, or worse skin contact/dust inhalation will give you severe radiation poisoning and probably kill you.
If something is not x-ray proof it's possible that it could still be resistant to gamma rays because the higher energy particle is more likely to pass through without exerting any energy into what it hits
"aw damn it, I accidentally dropped my sd card in Chernobyl"
"Oh dont worry, your data wont be lost, I just found a random youtube video regarding to this"
Perfect for those toughest times at the radioactive power plant
2:04 "I'm told it's the equivalent of a chest x-ray, so if you're due for a check-up..."
yea but chest x-ray is a short flash like the flash of a camera (actually even shorter). Sieverts x time = actually danger :)
@@BruceCarbonLakeriver Congratulations, the joke was right in front of you but you didn't notice it. That is a quote from Chernobyl TV series, " " were a clue, it's a rather famous radiation joke among people who watched the show. Also the units displayed by the meter already are in correlation with time, uSv/h.
@@bluef1sh926 oh it might be, sure. But I don't have the time for watching tv shows bud :)
@@BruceCarbonLakeriver r/woosh????
Can we now call this a hot SD card, or a spicy SD card.
YES!! He uploads on a friday. By far my favorite youtuber!
Thanks, David :D I usually aim for uploading the last Friday every month. This month I was a little ahead all the way. Sunshine and spring gives me an energy boost!
Thanks for the warning about data loss in outer space.
I'll keep that in mind next time I go there.
Oh good, that's reassuring. I had concerns that my Takumar lens with a thoriated (and therefore radioactive) rear element could scramble the firmware on the Metabones adapter I was using it on. This pretty much proves it's a nonfactor, as the worst numbers I could find for Takumars was around 8 uSv/h.
I didn't realize how much I needed to know this 🙌
Torbenite
Focuses on uranium
Insanely radioactive polonium decays
Something tells me that the micro SD card is in more danger of you dropping the sample on it than exposing it to radiation
I got atomic ache after watching this video. Thank you brainiac75 :)
when the geiger counter says SOS in morse, you know it’s time to get out.
No one
Absolutely no one
You:
Let's expose a SD card to uranium
Technically is not uranium pure, or the FBI will be on your door xD
Hehe, I am a niche channel with original videos. I will let mainstreamers take care of the mainstream :D
@@brainiac75 Mainstream is boring lol... Your channel is always informative and definitely filling in the cracks that many don't touch
I've wondered this tons of times. Every time I go through airport security I wonder about bit flips in my phone. I will wonder no more.
I think the nature of solid state storage may have something to do with the null result here; when unpowered, the data is in its most stable state. The data would be most vulnerable to corruption by ionizing radiation when it's in the process of being written to memory. You would need to have a device connected to the card and constantly writing data of a known hash to it while the card is being irradiated to have a likely chance of seeing a flipped bit.
Dam! was gonna swallow some of that stuff to erase the data on the chip in my head🤪
after reading this, the covid-19 vaccine chip in my head got mad
I don't know why i have head ache after watching this radioactive video
Try this again with a smart media flash card. They lack fancy things like memory controllers or error correction 😁
I could swear I've seen a few people at the airport ask for their SD cards to be checked manually instead of going into the X-Ray machine.
You can ask to have your junk checked manually instead of by the xray scanner. It is just as meaningless.
Nice testing! For the past few weeks I've been running a similar experiment, testing a Raspberry Pi 4 for online RAM bit errors using a radium watch dial (40cpm beta), with no bit errors detected yet. Evidently it takes quite a bit more radiation, or the energetic stuff like HZE GCR, to induce a measurable number of bit flips.
Maybe the testing data of these SD cards and RAM chips with beta and alpha radiation can be used to design high performance memory chips for future space probes. :)
@@thatguyalex2835 Yes! I actually started the experiment just to find out what data corruption pattern I should expect from radiation-induced soft errors, to help design error-tolerant software. (Two weeks ago I upgraded to a 500cpm thorium dioxide source, but I still haven't seen any bit errors in the 2GB of Pi RAM I'm watching...)
man really bought uranium to make a video, this is next level dedication
Would be interesting to see if there's any difference if the card is in operation vs powered, ie write a known file while in the radiation and then read it back both outside and then inside the field again..
I like your way of thinking. But I may have trouble testing it. I guess an external SD reader/writer could be opened and expose the card while writing. I just feel the intensity from my samples is still too low... Thanks for watching!
@@brainiac75 Easy enough to do, just get one of those USB memory stick card holders, and put the card in it. Then a ziploc bag around the card and a long USB extension cable, a powered hub and then the PC. Most likely the corrupted data will come from the USB converter, as those use much smaller feature RAM in them, which is a lot easier to flip bits on.
Another test will be to take an old desktop, nothing spectacular performance wise, with some DDR memory in 2 banks, with a gap between the banks (so a bank of 4 with only the outer ones filled) and place the green sample in a thin ziploc bag between them, and run Memtest for a few days, and see where you get the single bit flips, in the chips nearest the sample.
@@brainiac75 There are some really great little micro SD card breakout boards for like $2. The micro SD card holder is almost completely open and made of plastic. That should allow you to use an external micro SD card reader and a USB cable. That would be a great test.
At these levels there wouldn't be. This is not nearly enough radiation.
Well, I had never tought about this when we examined Uranium and 137Cs doses in biophysics class, I just put my phone right next to the samples haha. Quite interesting video, will look out for this in the future.- Pharm student
The flash memory chips are only on the top side of the PCB, since all that's on the bottom of the PCB is the solder mask (paint)
Uranium is so dangerous that I was afraid to click on this video
For the next video I'll blast this damned cards with a nuclear bomb.
The cards survive.
God damn it I have to make more content now!!!
2066: can a hard drive survive being shaken at 800k rpm while open?
@@UN4YA while there's a certain chance that the hard-drive can also create a blackhole.
If the cards do survive does that mean they are made out of nokia phones
@@genericname2948 you mean nokium?
Though, if you are talking about radioactive, then I think it should work fine. But the necular explosion is also causing the card to break since this thing got hit very hard.
Pretty sure that "x-ray proof SD card" is pretty much the same as "asbestos free cereals"
If you get an XRF spectrometer, one of those handheld ones, then point it at the card, that will do it.
Nice video! The reason for the absence of any bitflip is because the energy involved with this kind of radiation isn't nearly enough... even if the total amount is still considerable. Bit flip can occur from cosmic rays which travel at near the speed of light carrying an immense energy in comparison.
Lesson Learned:
Don't get your SD Card near that radioactive rock thing
Everyone: Radioactive
Me: I just love his SD card box, need one.
Neighbor : Son don't pick any stones from this man's home
Maybe you could try using RAM memory, using known good ram (memtest86), run the test again with some radioactive material strapped to it :)
That's an excellent idea. I would like to see that as well.
Yeah would be interesting
RAM doesn't store data when its not powered so this wouldn't do anything
@@GrandNebSmada It has to be in a motherboard and powered to run Memtest86 on it.

omg this makes my stomach drop to my feet. Just that little piece of green crap there. I found some when I was a kid that looked just like that at a Dinosaur Park. I played with and chewed on it. I noticed it was much harder than other rocks around, and I brought it to one of the scientists working there, he took it, asked me where I found it, then never gave it back. Did not tell me what I found. Just eek.
O: somebody uploaded, yay. this makes me happy
I was fully expecting some data corruption.
I decided to record the explosion of Herosima, but alas, the data was erased from the SD card, thanks for the video, next time I will be more prudent.
So now sd cards can survive laying between two rocks with a lot of radioactivity, but in the past when one chip factory used water with little radioactive particles, the chips were loosing data as hell
It's funny to believe that I would actually be a valuable candidate for the ESA in 6 years if I play my cards right as an Energy Engineer. That's honestly way better than I expected.
This whole time I was wondering if this channel was a continuation of the show Brainiac: Science Abuse
@Brainiac75 First of all, love your videos! I've experience on radhard for satellite R+D on microsd using Cobalt-60 ionizing source of a couple of curies of effective dose or aprox 200 gray hour. Originally intended to sterilising food products like dog/cat food or human food like apples for world-wide cargo shipment. Whatever we use, nothing can survive, but, the interesting thing you might be interested on is that we found the same equivalent results using radiotherapy low-end equipment, instead of spending thousands on a nuclear testing facility like before. Will gladly share anything on private.
Hi Marian! Glad to hear you like the videos. And thanks for sharing some of your experiences. I am definitely interested in hearing how you managed to affect a microsd with radiation. Can't write my e-mail here since all the bots will find it. My e-mail is however available on my channel here: th-cam.com/users/brainiac75about
If I saw a "gamma ray proof" label on an SD card, I would have so many questions...
Next step: Ship the card to the ISS and have them place it outside the station for a while
Are you chernobyl news reporter?
That SD card was formatted using the new TumorFS file system.
i love how calmly he talks about high radiation
Imagine accidentally tripping and falling face-first into the radioactive rocks.
Radiochemist here. The term Geiger counter is not an accurate term. It comes from the name of a type of detector used on a specific type of radiation monitor called a geiger muller tube. However other forms of detector exist such as a dual phosphor detector (other detectors on monitors are actually more common than the geiger muller tube). In general devices that measure activity in counts are referred to as contamination monitors and ones that measure dose rate are referred to as radiation monitors.
Pretty much all of the cheap hobbyist counters I've ever seen use GM tubes. They're geiger counters.
I have asked this my self but coincidentally I don’t have access to this sort of stuff, I expected something to happen considering how complex these tiny things are, incredible how durable flash storage is
This is more a demonstration of how feeble his radiation sources are and not how robust an SD card is.
_To conclude:_ The more expensive SD cards marked X-ray proof are nothing more than marketing bull💩.
the geiger counter doing an sos is like "Help me" "im outta here"
Thanks for telling me this. Now I know that my SD cards will not be harmed when I explode a nuke in them, except for them being vaporized.
The closest I got to something horribly radioactive was decades ago when my high school teacher brought out a clock with radium dials. The Geiger counter had a poop fit when he brought it near to the clock. Even at that young age I was horrified when he picked up the clock with his bare hands (hand touching the dial painted with radium).
uranium basically emits alpha radiation, which corresponds to the helium nucleus. a sheet of paper can shield this type of radiation. The card was covered with a sheet of paper, which shielded much of the radiation emitted by uranium. in addition, there is the plastic around the SD card chip, which will also shield much of the radiation. with that, the dose that the chip received was far below that shown in the video. for this type of test, the correct thing would be to use other types of radiation more penetrating.
Those angry rocks ain’t very scary to me. Can’t even hurt a puny SD card, I can take them on!
- famous last words
From my nuclear power plant experience of qualifying consumer electronics for nuclear use, I'd say that you would need multiple Sv (yes full Sieverts) to move the needle and see something happen.
“I want my sd card to be resilient in all situations...” So... you're planning to use it in a nuclear power plant?
Imagen having such balls to be near radioactive material, we just dont know if he had protection
Ugh, I hate when I accidentally take my SD card into a super highly radioactive room
the fact he uses powershell for checking the sd card and not CMD is incredible
Holy crap i forgot about this channel for so long
Fun fact: 860 micro siverts / h is 0.086 Roentgen / h. Chernobyl was 15000 Roentgen / h or 150 000 000 micro siverts / h (150 siverts / h)
Issue with this test is Uranium is mostly an alpha emitter and alpha particles will only interact with the surface of the card, not the inner data storing flash memory. You would need a strong gamma source to affect the internal parts of the SD card
Uranium ores have a massive amount of built up radium from millions or billions of years of decay of the uranium. The radium is the primary source of gamma radiation in uranium ores.
Wasn't sure what to expect going in. Seeing the results is nice to know.
WTF? Your strongest example is from close to where I live! Greetings from Chemnitz!
IT’S OVER 9000!! 6:16
A MicroSD card is actually not chips on a board, rather, the entire thing is a single flash chip with on-die controller. Some USB drives are also of the monolithic design.
"Natural samples didnt effect sd card"
Chernobyl reactor 4: hold my beer
this guy is 1 lab accident away from getting some super powers
Another question is, will the geiger counter fail if the radiation is too high? It contains flash memory and a microprocessor too...
Is he literally keeping an sd card on a radioactive element by holding normal tweezers with bare hands (in the intro and normal pair of gloves afterwards)!
a strontium 90 source may work in this situation since data on sd cards use electrons and strontium 90 is a beta emitter so that could work better great video though!
The SD card turns into the Hulk 😂
I don't like how they easily corrupt when we don't want them to
now i feel the weird urge to mill a microSD slot into a solid radioactive rock
I don't think that you can consider the natural background radiation in your house as normal background radiation...
