      All batteries are made up of a number of cells. What people commonly call a "battery" (like an AA, a C, a D, or an AAA), is actually a cell. If you look at your car battery, you might be able to see that it is made up of six cells. Each one has its own compartment, and its own plug on top for adding more water if it gets low.

      The reason for this is that a cell puts out about 2 volts. To get a higher voltage, you have to connect several cells in series to make a battery. For a car, you need six cells to make twelve volts. For a telephone exchange, you need 24 cells to make about 50 volts. You can also connect several batteries together in parallel to get more current or more power.

      Most parts of a computer are "immune" to xrays. Meaning that the computer doesn't get damaged by them.

      However, CMOS EEPROM cells that are designed using buried gate transistors (which is the most common type of EEPROM these days) can be damaged by xrays. If an xray passes through the buried gate to the channel, it'll ionize a bit of the silicon dioxide insulator between the buried gate and the channel. This makes the charge leak out of the buried gate somewhat faster. The more xrays that pass through that area, the more ionization and the faster the charge leaks out. This ionization is irreversable, and causes permanent damage.

      Whether the damage actually causes the bit in question to revert to a 1 depends on the strength of the xray source and how long (total across all the sessions) your computer has been bathed. An airline xray machine is unlikely to erase a bit if your machine passes through once. But if you travel a lot, then its almost certain that you'll suffer at least a one-bit error.

      In short: don't let the airport security goons xray your laptops, palm pilots, digital cameras, or anything else that has CMOS EEPROM memory.

      Every airport security checkpoint in the US has alternate procedures for electronics (generally involving a swab and a "portable" gas chromatograph to search for nitrogen compounds). The goons will argue with you, but it's worth the annoyance.

      I've done this in Las Vegas, Los Angeles, San Fransisco, San Jose, Seattle, Denver, Sioux City, Minneapolis, and New Orleans. Those airports pretty much run the gamut of size from little podunk warts to huge transport hubs.

      Answer: The X-ray levels used are very low and may cause damage to 1 in a 100,000 units.

    5. Re:X-Rays and computers? by sinster · · Score: 2, Informative

      When I was in college, the probability was closer to 1 in every 1000 scans. These days, the airport xray machines are much stronger than back then. I can't cite a new probability, because I don't know the new radiation strength, but it must be lower than 1 in 1000.

      The critical question is, "Will you notice the damage?" We're talking about a one bit error, here.

      Take your average PC. You've got pretty much three firmware chips in there: one for the system BIOS, one for the hard drive firmware, and one for the video controller. No matter which firmware suffers the error, there's first a question of whether or not the error is in a memory cell that ever gets accessed, and second whether or not the error changes the value in a way that makes a difference. If we're talking about one of those lame bootup graphics that a lot of manufacturers like these days, you'll probably never notice a one bit error. And if we're talking about code that drives a piece of hardware that you don't have installed (or dont use) you won't notice that error either. But if you get an error in your POST code, you're dead. System BIOSes these days are pretty fluffy. Lots of extraneous stuff in there. Video firmware is also pretty fluffy, but not nearly as bad as system BIOS. And drive firmware is quite tight. Almost any error you get in there will be in some code that gets executed.

      But on the other hand, the Intel opcode set is full of lots of unused bits. There are a whole lot of examples where flipping a bit from 0 to 1 doesn't change the opcode or operands. And recall that we're talking about errors that can only change a 0 to a 1; there is no way that xray damage could change a 1 to a 0. If the bit that gets damaged is already a 1 (~50% chance of that) then your dead memory cell is still functioning exactly the way you want... until it comes time to do a firmware upgrade.

      So that brings us to the last two issues: given that damage occurs, and given that its noticeable, then how long will it take for you to notice it, and will you ascribe the damage correctly to the airport xray machine? Many users are perfectly happy to ascribe crashes and corruptions to Windows. And while Windows certainly accounts for more than its fair share of errors, on a machine that crashes once every 40 hours, are you going to notice and correctly assign a failure that makes it crash every 39h30m?

      Lastly, we're not talking about a bit suddenly changing from 0 to 1. Normally a buried gate transistor will hold its charge for around 150 years (each transistor will be different). No insulator is perfect. You zap it with a single photon, and maybe you've chopped a year off that. Of course, a xray machine isn't going to output a single photon. It's going to bathe your machine in a tremendous number of photons. So maybe one airport xray machine will drop you from 150 years to 130 years (I'm pulling that 20 year figure out of my butt, pretty much, but it's within an order of magnitude of being right). Do it again, and we're down to 110 years (it'll always reduce the life by the same number: a single xray photon opens a single ionizied path in the silicon dioxide, and that single ionized path will saturate at a small fixed current). So after 8 hits in the airport xray machine, you've probably got a number of one bit errors. And then the discussion above about whether or not you'll notice the error and whether or not you ascribe it correctly comes into play.

      PS: these days, most microcontrollers, PICs, CPUs, MMUs, and other assorted large chips also have EEPROM cells on board. But in any particular computer, the technology used to design the EEPROM cells in functional chips is usually 5 to 7 years ahead of the technology used to create EEPROM cells in memory chips. That means that if your CPU is using a .2um technology (that tells us that the transistor channel will be .2um x .4um in EEPROM memory cells), then your bulk EEPROM is probably using a .5um or 1um process. That means that not only does your bulk memory have far more EEPROM transistors, but that each one is 6.25 to 16 times as large. For this reason, we can ignore the probability of getting a one bit error in your CPU when discussing the likely places for errors to occur. But a rigorous discussion would require that we pay attention to all EEPROM cells in a computer.

For example, visible light is easily blocked by little solid matter, even a 1mm sheet of aluminum is enough to block all but the most intense lights. On the onther hand, radio waves will go right through. That's why you can pick up TV signals in a room, even if little outside light is getting in.
