  • 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!

    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.

    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.

    Hi! Just wanted to chime in and say that I fly CubeSat satellites in low-earth orbit. They face a ton of radiation all the time. One of my satellites has 5 different SD cards onboard, and they're all just normal ones you can get at any electronics shop (not radiation hardened or anything like that). They haven't had any data errors, which is great!
    One thing to be aware of is that SD cards require a relatively high voltage (over 10 volts or so) to erase their contents. This voltage is generated by a "charge pump" which boosts the voltage from the normal supply voltage. However, charge pumps aren't very good in radiation environments, so over time they can die, which ultimately ends up making your card fail into a read-only state. You'll never see issues with your files, but you will find that you can no longer CHANGE the files.
    Just a thing to be aware of, might be worth testing these irradiated cards for this failure, or give them some more time and see if they go read-only!

      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.

      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.

      The handling techniques in this video are vastly, VASTLY overkill for the levels of radiation and contamination present. He's doing it that way mainly for entertainment value. The risks from handling a piece of uranium ore for a few minutes that isn't shedding any significant amount of dust and washing your hands after touching it are probably on the order of taking a flight from NY to LA - ie. utterly trivial. Phil Mason's personality may leave a LOT to be desired but his radioactive material handling practices are perfectly adequate.

    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.
