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. "

What?

The summary says "radiation-proof robot", but TFA says "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."

I'ma call shenanigans on this one. And "making life easier for folks in the military?!" In ONE instance, this helped what happened to be a Military research plant. But the poster makes it seem like this'll win the war in Iraq. Seriously, this is a HORRIBLE scew to put on the article.

Rant aside, I think this is very interesting problem solving. Especially the 10-foot poll bit. Just goes to show that technology can't win everything. Not by a long shot. Interesting problem, interesting solution, both very complicated.

emphatic re-iteration

Article says: "The cause was a stuck cylinder the size of a restaurant salt shaker but considerably more deadly: Gamma rays from the cobalt-60 it contained could kill a man in half a minute."

I have to ask...when did restaurants start serving salt that's only somewhat less deadly than cobalt-60?

Also remember they have to then encase the robot in a protective sheild when it's done since it's still radioactive. Then they have to use a truck or such to dispose of the container, and then the truck needs to be encased since it's not radioactive, too. Don't forget anything else that even assisted.

No, I'm not kidding.

Yes you are, or you're an idiot. Explain to me a process by which gamma rays can activate an object. Hint: consider a gamma splitting deuterium to release a neutron which then goes on to activate other metals. Now tell me the energy of the gamma and which radioactive materials release gamma rays at that energy. Now add in the probability of activation (it is not a highly probable reaction) and the scarcity of deuterium (0.015% of hydrogen). Now describe the mean free path of the neutron (obviously there must have been a lot of water or highly hydrogen rich materials there for it to come from deuterium) and explain how the 'radiation' spreads.

If you can do this and still keep a straight face, you are a f***ing idiot. Otherwise you were kidding.

The cylinder normally arrived and departed through a metal sleeve, driven by pneumatic air. The method resembled that used by drive-up banks, where pneumatic air drives a cylinder containing transaction paperwork first one way and then the other.

At White Sands, a pressure of approximately 20 psi was normally enough to move the container from its secure resting place to its forward exposed, or live, position; the same air pressure in the opposite direction sent it back. 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.

...

...Inspection revealed the problem: Forceful early attempts to blow the cylinder back apparently had bent the straight switch into a right angle...

Idiots.

Perhaps this event will help set a new model for operational safety. I can't believe how stupid those operators were. It never occurred to them to send out a fucking maintanence tech to inspect the mechanism and figure out why it was sticking?

I seriously doubt that the manual (it's the DoD, you know they have a manual for this) included "up the PSI" as a way to resolve the issue.

I don't think anyone should be fired over this, but i expect them to review all their procedures for problem solving with respect to their radioactive materials.

As for nucleur power plants, I think it'd be best not to increase the use of remote robots. The more human inspection is required, the more shielding they have to use, which imho is a good thing.

morons ...

[Anonymous Coward]

why are they still playing around with this stuff anyway?
it's super dangerous!

"Unfortunately, heat from the radiation source melted the plastic. "
i wouldn't want to be alive after a nuclear world war, and i'm pretty
sure you wouldn't want to be either, so screw you and your
radiation proof circuits ...

but then again .. that might not be the real reason they're playing
around with this stuff in the first place ... tachions and and
space-time displacment fields anyone?
