Robot Saves the Day at Radiation Lab 235

Posted by ScuttleMonkey from the johnny-five-is-radioactive dept.
An anonymous reader writes "Nature.com is reporting that records released this week by the US defense department read almost like a bad movie plot. Back in October a high-security radiation lab had a cylinder filled with radiation get trapped in its delivery tube network. Fortunately a specially designed bomb-disposal robot was able to retrieve the canister before the radiation was able to eat its way free.

    First the "Robot Saves Troops" story and now this. Pretty cool how robots are actually helping us nowadays.

    "By now, the robot had been in the radiation zone for 90 minutes. The team decided to regroup, but the robot's electronics had failed and it was rooted to the spot. Thankfully, the team had tied a rope around the machine, and it was hauled in, almost knocking over a radiation shield in the process."

    This part sounds remarkably familiar...

    "On the third day, and after three weeks of continuous warning sirens..."

    Whoah. It took them THREE DAYS? I'm glad this wasn't (obviously) a really serious problem. If it were some sort of radiation based bomb, they'd get fried.

    From reading these two articles, it seems that if we could somehow shield these robots from outside radiation, these jobs would be done in a flash.

    Unfortunately, we need them to recieve radation because if they DON'T, we can't communicate with them.

    Now, I'm not a physicist, but might a Faraday Cage (http://en.wikipedia.org/wiki/Faraday_cage [wikipedia.org]) built with an appropriately sized mesh do the job? Just as a microwave lets some radiation out (we can see the burrito cooking inside) while keeping the harmful radiation in (we don't get toasted by the microwaves), couldn't this be used to do the reverse, that is, allow communication in while shielding the robot from radiation?

    I realize that these cages must be in a specific shape to work correctly, but if the core components at least, can be shielded, this go a long way towards solving our problems.

    Heck, the arms and stuff we can even make (god forbid) mechanical, perhaps in such a way that they won't get owned by the radiation at all.

        Actually Cobalt 60 is a Gamma emitter. Gamma is EM but very high frequency. The majority of the radiation from it is not particle radiation unless you count photons are particle radiation.
        The holes in the shielding on a microwave have to be smaller than the wavelength of the microwaves. Gamma has a wavelength smaller than visible light so the holes would have to be too small for even light to pass through. It is also a lot more energetic so the thin metal shielding used in a microwave wouldn't be of much use. So a faraday cage "could" work if it was thick enough and had small enough crystal structure the be effective the only problem is I don't know of any material that meets those requirements off the top of my head. A high density shield of say, lead would be far simpler.

      I realize that these cages must be in a specific shape to work correctly, but if the core components at least, can be shielded, this go a long way towards solving our problems.

      It isn't the shape of the Faraday cages that's special. It's the size of the mesh. The mesh has to be significantly smaller then the wavelength of the radiation you are trying to keep out. Microwaves have a wavelength of 1-300mm. The wave-length of gamma rays is less then 0.00000000001mm. That's much smaller then the distance between atoms in a typical solid, so the idea of a mesh becomes kind of absurd.

      I doubt that the problem with shielding is communications. After all you could put the shielding on the side facing the radiation, and leave the side towards the crew open. Gamma radiation doesn't go around corners. Or, as others have suggested, you could just run a cable to the robot. I think the actual problem is weight. Lead is heavy. You might be able to pile a ton of lead around the cpus and memroy, and just crank up the horsepower of the motors. However, by their very purpose you can't put the sensors behind lead sheilds, since all they would see then would be the lead shield. Not very helpful.
      • The property of gamma rays to pass through anything is actually used to make shielded sensors and cameras. The optical wavelengths are bounced into the sensor with mirrors or prisms, while the gamma radiation goes through the mirror and past the sensor. It's not perfect, and you need a point radiation source and enough shielding to matter around the sensor itself, but it can be done.

      The article that I read several days ago said that they use the cobalt-60 to test radiation resistance... they want to see the effects that high radiation levels will have on various pieces of military and civilian hardware. They set up their test gear, shuttle in the cobalt via pneumatic tube, let the gear cook in the extremely intense radiation, and then shuttle the cobalt back into a 'safe' area. I believe the original article claimed that cobalt is good for this, because it doesn't make the whole area permanently radioactive, though I'm not familiar with the reason why. (gamma radiation, maybe???)

      The writeup on the article is misleading. Radiation doesn't 'eat its way free'... fer chrissake, people! Acids eat things. Radiation just ... radiates. And it was ALREADY free, that's why the needed the darn robot. That whole testing area was absolutely lethal to human beings, even in heavy protective gear. Even the robot couldn't survive it very long... they thought 50 minutes. In actual practice, it lasted longer... but the movement system did fail, so they had to drag it out with a rope.

      To the person asking about building a Faraday cage around it.... as far as I know, a Faraday cage isn't an absolute barrier, it's just a very strong one. It attenuates a signal by a very great deal, making signals interception very difficult. But in this case, the 'signal' (the cobalt) is so incredibly powerful that a Faraday cage would just take the edge off, as it were. If my limited understanding of radiation is correct, it'd be just about as effective as sunglasses in front of a supernova. (and I'm not sure that Faraday cages even *work* at these frequencies... the radiation might just punch right through the shield material.)

Co60 is commonly used in industry for sterilizing and for killing off bacteria on food (it is also used in gamma-ray photography industrially). Cobalt 60 can be produced from bombarding iron with nuclear radiation, like inside a nuclear reactor or near a nuclear explosion.

Then, when the repair was finished, the elements had to be loaded back into the reactor. Over time, we unloaded and reloaded 39,000 fuel elements. All of the plant's personnel took part in this work and they received huge doses of radiation. The repairs were finished in two months." "several hundred kilograms of freshly irradiated nuclear fuel got stuck--men from everywhere in the plant were called out, and one after another they used long steel rods to push the elements into the apparatus. The only protection they had was cotton overalls and gloves."
  • Unfortunately the robot failed anyway, with only 5 minutes left until the radiation leaked out, destroying civilisation in an evil terrorist plot. Bruce Willis had to throw himself into the chamber and heroically sacrifice his life in order to correct the problem manually. After fixing the radiation leak, he managed to crawl into and activate an experimental cryogenic chamber stored in the same room, before expiring from the overdose of radiation. The probability of him being revived for a sequel is high.

      I thought that was a Star Trek episode.

      No, wait - an Andromeda episode.

      Or maybe an SG-1 episode.

      Or was it an Angel episode? Or maybe Buffy.

      We used to complain about multiple dupes on the front page every day. Literally the same story two or three times in a row.

      Sometimes the editors bring back 'old' stories because they think there is more discussion to be had... sometimes they're just fucking up.

      I still don't understand why there is no mechanism for even a basic keyword comparison that can pop up and tell the eds "a story with similar w

    "...before the radiation was able to eat its way free." That's choice. Sounds like the tagline from some poorly-researched sci-fi or action flick. Besides, the radiation was already present outside the canister; otherwise, there would have been no danger to personnel and no radiation alarms sounding.

    As for the comment about the container being filled with radiation, I could excuse that as simply a mistake of terminology. You can fill the container with active or contaminated material, but you can't fill it with radiation itself. Contamination is the shit. Radiation is just the stink.

    A more practical analogy would be light as an example of radiation. You can fill a box with flashlights, and you can shine light inside a box, but you can't fill the box with light.

    The article makes reference to the radiation eating away at the robot's circuits. This is pure speculation, but I think this may have been a reference to the effect that high energy gamma radiation can have on digital circuits such as memory. That would be a bit of a metaphor, not a literal corrosion of the circuitry. Certainly, it does not imply that the canister was in danger of impending failure.
    • High levels of radiation has a nack for breaking down many materials very quickly. Plastics and organic compounds seem to suffer the most, as the insulation on wiring turns brittle and flaky quite fast at about 1k rem. Working at a CANDU nuclear power plant, everything but the video cameras that monitor the reactor face uses special wires to prevent common short circuits. So you can tell from that that we replace the video cams quite often. Or worse (and usually the case), they stop working and we don't

  • A plucky little expensive robot was destroyed while saving the day recently at the White Sands missile range after gross incompetence in the fields of engineering and risk analysis manifested as a lump of highly radioactive substance becoming stuck in a tube, prompting technicians to attempt to fix the problem basically by kicking it really hard, which broke it even worse, at which point several people valiantly tried to fix the problem with a tool that was not designed for that purpose--since nobody had a

  • Why couldn't they have used sneakernet like everyone else?
  • It is impossible for a tube to be filled with "radiation". Radiation would be emitted spherically in all directions from the tube, subject to the inverse square law. That is, unless one was far enough away from the tube for it to be considered a point source. What the tube was filled with is "contamination", which is the source of the radiation. Contamination is the "sh*t"...radiation is the "stink".
