Radiation Robot Makes Troops Safer

Darkman, Walkin Dude wrote to mention a plucky little radiation-proof robot working to make life easier for folks in the military. From the article: "By this time an hour and a half had gone by, and the team was temporarily out of ideas. Phil had estimated that the robot could remain ambulatory in the radiation field for only 50 minutes, and in fact the robot's lower portion was no longer responding to commands. The RAP team, as a precaution against this very circumstance, working with White Sands personnel had tied a rope to M2 before sending it into the work area. The rope, attached to a RAP team winch 100 feet outside the structure, ensured the robot could be hauled out if radiation damaged its drive unit. But radiation shields now blocked a direct haul. M2 was hemmed in. Using a ten-foot-long pole and standing at the edge of the field (which fanned out like a flashlight beam, strongest at its center and weakest at its edges), team members hooked and then tugged at the rope hauling M2. The deflection of the rope's pull slid the robot around a moveable radiation shield without knocking it over. The RAP team's winch then pulled the robot directly out. "

    Seconds later, Sarah Connor grabbed the pole and impaled the robot, destroying its primary power supply. Even as its eyes went dark, emergency systems kicked in to begin rerouting secondary and tertiary power systems.

    Wise to the design of robots, Sarah and her son, future savior of humankind John Connor, shoved the robot through a nearby doorway conveniently located right above a steel foundry where it dramatically screamed in electronic pain for a few seconds. And then it was over.

    "Is it over, mom?" John asked, panting.

    Sarah Connor wiped the sweat out of her eyes. "It's over," she said as the familiar industrial movie soundtrack theme began to play. "It's over."

      Gamma rays and X-Rays are basically the same thing - ionizing electromagnetic radiation. Electromagnetic radiation can induce currents in a piece of metal that is moved through its field and these unwanted currents can play havoc with the circuits inside a microchip, perhaps even overloading and burning them out. The gamma rays could also alter the bits in the memory chips so the software running the robot could crash.

      Ionizing radiations (usually beta/gamma radiation) can affect materials in various ways. For example, an energetic gamma-ray photon (around 0.3 MeV for the Cobalt-60 spectrum) would cause partial ionization of Si atoms in traditional semiconductors. Since the n/p difference is extremely small in a single transistor, you just need a few thousand ionizations in it to make it unusable.

      I don't know, franly, but I am not sure about using tubes because as someone else pointed out, beta radiation (and gamma rays too) would ionize the rarefied gas inside the tube, therefore affecting the flow of electrons (in fact this is one of the principles behind various designs of radiation detectors). But probably it might work in some conditions.

      Another solution would be to use hardened semiconductors, with much bigger gates, etc. For example, in space you have cosmic rays (which, BTW are much more energetic than nuclear-generated gamma rays). NASA is using hardened electronic components which are able to withstand the random ionization generated by cosmic rays.

Over previous decades, on the rare occasions when the cylinder stuck, technicians had merely increased air pressure to send it on its way.

      But this problem was different. From the safety of their control room, technicians increased air pressure in steps until they had reached 50 times normal, or 1000 psi, but they could not budge the cylinder.
